pyMC Introduction

2026-05-12T00:00:00+00:00

What is pyMC? At its core, pyMC is a Python implementation of a MeshCore-compatible stack. It is designed to run on Linux-based systems and connect embedded LoRa radios to higher-level software services. It started as a way to better understand the MeshCore protocol. But pretty quickly, it became something more useful: a reusable core library for building flexible, Linux-powered mesh infrastructure. The pymc core handles the protocol-level work:

Parsing and generating MeshCore packets
Managing identities and addressing
Maintaining compatibility as the protocol evolves
Handling radio interfaces (SPI, KISS, USB-CH341)

with over 15 boards currently supported and many new ones in development, the system has grown from a simple experiment into a practical toolkit for building and running distributed mesh infrastructure.

On top of pyMC core sits pymc repeater, which handles the operational side:

Processing packets
Applying routing and filtering logic
Forwarding traffic
Supporting services like roomservers, companions and observer data output

Embedded firmware is efficient and well suited to dedicated devices, but it operates under tight resource constraints. Running pyMC on Linux expands the design space: more compute, better tooling, easier debugging, and deeper real-time visibility into mesh behaviour.

A key design choice is how identities are handled. Instead of assuming one physical node equals one logical presence, pyMC lets multiple identities exist on the same radio.

In practice, a single device can take on multiple roles. It might act as a repeater, represent different logical endpoints, or host additional services–each with its own context.

This flexibility allows a pymc repeater to evolve into a multi-companion base station. At that point, it behaves less like a simple packet repeater and more like a lightweight message hub for the mesh.

Put another way: pyMC gives MeshCore a Linux-native surface area. It can run repeaters, host services, power analytics, or support entirely new mesh applications–without losing compatibility with the underlying radio layer.

Where pymc_console fits

One example of that larger design space is pymc_console: a browser-based dashboard built on top of pyMC repeater.

Where pyMC handles the protocol and repeater layer, pymc_console turns that activity into something you can actually see and reason about. Packet flow, radio status, connected identities, observer output, airtime utilization, and network behavior can all be surfaced in a more approachable interface.

That matters because a mesh network is difficult to improve if it is invisible. Once packets, routes, signal quality, and utilization patterns become observable, the repeater becomes more than a forwarding node. It becomes a local window into the health and behavior of the mesh.

In that sense, pymc_console is less a separate idea than a natural extension of the pyMC architecture. The same Linux-native foundation that lets pyMC talk to radios also makes it possible to build analytics, dashboards, companion experiences, and new tools around the mesh.

The interesting part isn’t just what pyMC does today, but what it enables in practice.

If you’d like to explore it, run it yourself, or follow along as it evolves, everything you need to get started is available.

Ripple UI v9.7

2026-04-30T00:00:00+00:00

The latest release of the Ripple UI firmwares has had quite a big overhaul (under the hood) and the UI now sports a Light and Dark mode theming, plus you can now customise the accent colour used throughout the firmware.

Display Preferences

The Display menu now shows these preferences:

The UI Theme preferences is one of: Light, Dark or Auto. The Auto option automatically switches the UI theme depending on the Brightness setting (day or night).

PAID FEATURE: The Accent color lets you customise the accent colour used throughout the firmware. There are 10 fun colour swatches to select from:

Map Theme

Note that the UI Theme preference also determines the light/dark theming for the maps:

Download

The v9.7 is now available for LilyGo T-Deck, T-Pager and the T-Watch S3 Plus. It will be rolling out soon for the other colour devices, like Heltec V4 Expansion kit, etc.

These are now available in the MeshCore.io Flasher, for easy installation.

Meshcore.io - Why The Split?

2026-04-23T00:00:00+00:00

Since inception, the MeshCore development team have been working hard to build MeshCore.

We’ve released more than 85 versions of the MeshCore Companion, Repeater and Room Server firmwares with support for more than 75 hardware variants. All of this has been hand crafted, by humans.

We have always been wary of AI generated code, but felt everyone is free to do what they want and experiment, etc. But, one of our own, Andy Kirby, decided to branch out and extensively use Claude Code, and has decided to aggressively take over all of the components of the MeshCore ecosystem: standalone devices, mobile app, web flasher and web config tools.

And, he’s kept that small detail a secret - that it’s all majority vibe coded.

We ran a poll recently, and asked in the MeshCore Discord about AI and trust, and these are the results:

The team didn’t feel it was our place to protest, until we recently discovered that Andy applied for the MeshCore Trademark (on the 29th March, according to filings) and didn’t tell any of us. We have tried discussing this, and what his intentions are, but those broke down and we now have no communication with Andy.

It’s been a stressful few months trying to sort this out, and is now a sad day to bring this out to the public. It’s been a slap in the face to the team that have worked so hard on this project, to have an insider team up with a robot and a lawyer.

“Official” MeshCore

The use of the ‘official’ status is what is currently being contested. Andy is adamant that he owns the brand, and is using the word very heavily with his MeshOS line.

Meanwhile, in reality, the only ‘official’ MeshCore is the github repo. It’s the source of truth in terms of what is MeshCore, and Andy has never contributed to that.

Since the internal split, we launched the meshcore.io site, as Andy controls the meshcore.co.uk site and original discord server. We’ve been left with little other recourse. And, since launching the site, Andy copied the look and feel (again, using Claude) even though we asked him not to.

Project Growth

The MeshCore project has been on an incredible journey.

Having only started in January 2025, we have grown extremely fast!

As of this post, the official MeshCore Map shows 38,000+ nodes around the world, and the official MeshCore App has more than 100,000+ active users across Android and iOS.

It’s pretty epic how we’ve all built such an incredible community in such as a short time!

As the project grows, so does our need for a dedicated space that provides you with official information from the core team.

In recent times, we’ve seen an explosion of growth in MeshCore web sites dedicated to specific countries and mesh communities.

To name a few, we’ve seen:

MeshCore Portugal over at https://meshcore.pt
MeshCore Switzerland over at https://meshcore.ch
and the first successes with MeshCore UK over at https://meshcore.co.uk

Andy Kirby did do an amazing job helping to promote the MeshCore project on his personal YouTube, but only promotes his own products now.

Where To From Here?

So, the core team are pushing ahead with the meshcore.io website, the ongoing work of firmware feature development, bug fixes, managing PR’s and developer discussions, etc.

We now release change logs, blog posts and technical documentation for all of our new firmware and app releases here.

You’ll also find some familiar faces on our blog posts, such as:

Scott our project founder, lead firmware engineer and developer of the Ripple firmware!
Recrof our official MeshCore Map developer and Firmware Flasher guru. He has shared some insights into the early development of the MeshCore Map.
Liam Cottle the official MeshCore App developer who will be posting useful guides for getting started with the MeshCore App.
FDLamotte who has done epic work on the Python tooling for MeshCore, as well as the STM32 firmware variants.
Oltaco (Che Aporeps) who has done amazing work on the new OTA Fix bootloader that makes firmware updates much more reliable.

The Core Team

The MeshCore team, now consisting of Scott, Liam, Recrof, FDLamotte and now Oltaco remain committed to designing and developing high quality, human-written software.

Default Scope Region

2026-04-17T00:00:00+00:00

NOTE: Refer to the previous blog post if you are unfamiliar with regions/scopes

Since the v1.12.0 firmware release, scoping group channel messages has been possible, but there are still a number of road-blocks to using regions more effectively, especially for meshes like in Germany who are trying to disable un-scoped traffic (ie. region denyf *)

In the next release (v1.15.0) there will be a new concept of ‘default scope’, for both companion nodes and repeater/room server. This will make it possible to do scoped DM messages, login requests, stats request, etc. (even in a mesh that has disabled un-scoped flood traffic)

Mobile App

The MeshCore app ver 1.43.0 will have a new setting in the Experimental Settings screen. Here you can set the default scope region name.

When set, ALL flood packets the companion sends (eg. adverts, DM’s/logins/requests when path is unknown) will be scoped to this region.

Group channel scope, if set, will override the default scope. So, you can still have (typically) smaller region/scope for individual channels.

Repeater and Room Server Admin

From v1.15.0 there will be a new cli command:

region default {name | <null>}

This sets the given region as the default scope, or clears if you specify <null>. Note that the region is auto-created if currently not in the regions list. Also, an implicit region save is automatically performed!

Default scope is only applied to packets which originate from the repeater/room server. So, only adverts for repeater. Adverts and room posts for room server.

Logins/Requests/Commands and Responses

From v1.15.0 there is a new rule for responses. These originate from repeater/room server, but have this rule:

If request packet scope can be resolved (ie. Region is in its list) then same scope is used for reply
Otherwise, reply is sent un-scoped.

This includes the case of un-scoped request will have an un-scoped reply.

For now, this is the safer option, instead of having the replies default to the default-scope. While in this transition period, there are too many ways a repeater admin could shoot themselves in the foot and lock themselves out of their own repeater!

EXTRA: new ‘put’ default

The region put ... CLI command now defaults the new region to ‘allow’ for flood. So, you won’t need to also follow with region allowf ...

Standalone Devices

For Ripple GUI supported devices, like the T-Deck, the next release (v9.6) will have default-scope support. From the Regions screen, just select a plain region (or ‘*’) and in the details screen, select the menu:

(If needed, create a new region from the main region list, for the default scope)

Back in the Regions list screen, you should see a (S) displayed next to the current default scope region:

FAQ

Q: As a repeater admin, what should I set default scope to?

It should typically be a large region, eg. your city. Or, whatever the region that you wish to confine adverts to (for instance).

Q: As an app/chat user, what should I set default scope to?

This should be a large region which will safely include both yourself and the contact(s) you wish to DM. Both your messages, and the returning ACKs will be scoped to this region.

Q: I manage regional MeshCore firmware builds, with best defaults for the region. Can I configure a custom default region in my builds?

Yes. In the relevant .ini files, just add to build_flags -D DEFAULT_FLOOD_SCOPE_NAME='" .. "' (with the name in quotes)

Installing the OTAFix Bootloader

2026-04-06T00:00:00+00:00

Background

When I was first getting into MeshCore I realised that nRF52 devices had the ability to do OTA updates via BLE, which is obviously a great feature when you need to update a repeater which is on a roof.

Unfortunately I never had much luck getting this to work. If you were lucky and used the right settings it might work with RAK4631 but particularly with ProMicro devices it never worked at all. This led me to dig around in github where I found some ancient forgotten PRs to fix some of these issues.

Since they weren’t getting any attention on the official Adafruit github I took it upon myself to fork the bootloader and include these fixes myself.

Installing the OTAFIX Bootloader for nRF52 devices

For the best nRF52 OTA update experience, it’s recommended to upgrade your device to the OTAFIX bootloader. This version includes:

Automatic fallback to OTA DFU mode if an update fails
Significantly faster OTA update speeds
Additional quality-of-life improvements for certain devices, like to the ability to enter OTA DFU mode by holding a button while resetting.

1. Enter UF2 DFU Mode

First, put your device into UF2 DFU mode.

For most nRF52 devices:

Plug the device into your computer
Quickly double-press the reset button (twice within 0.5 seconds)
A UF2 USB drive should appear, the name of the drive will differ depending on the device.

Some devices use different methods, see the notes at the end of this guide.

2. Check Your Current Bootloader (Optional but Recommended)

This step is important for devices like the Seeed Studio XIAO nRF52840, which often ship with the SENSE bootloader variant.

To check:

Enter UF2 DFU mode
Open the INFO_UF2.TXT file on the mounted drive

This file contains details about your current bootloader.

Example: If the file shows: Board-ID: nRF52840-SeeedXiaoSense-v1 then you will need to install the SENSE variant.

3. Download the OTAFIX Bootloader

You can now download the OTAFIX bootloader directly from the MeshCore flasher site! Go to https://flasher.meshcore.io

Select your device
Choose Repeater
A download link for the OTAFIX bootloader will appear in a highlighted banner, the file will be titled update-xxxx.uf2

Alternatively the OTAFIX bootloader is also available from the official site. Go to:
https://github.com/oltaco/Adafruit_nRF52_Bootloader_OTAFIX/releases

Download the correct UF2 file for your device from the Assets section.

Files are named like: update-xxxx.uf2
You may need to click “Show more” to see all available files

Example: For the Seeed Xiao Sense variant as discussed above you will want to download update-xiao_nrf52840_ble_sense_bootloader-0.9.2-OTAFIX2.1-BP1.2_nosd.uf2

4. Install the Bootloader

Drag and drop the update-xxxx.uf2 file onto the UF2 drive
The device will automatically:
- Update the bootloader
- Reboot when complete

5. Verify the Update

Re-enter UF2 DFU mode
Open INFO_UF2.TXT again

The version line should now include OTAFIX.

Device-Specific Notes

T1000-e DFU Mode

To enter DFU mode:

Attach the magnetic USB cable
Hold the button
Quickly disconnect and reconnect the cable twice

Video reference: https://www.youtube.com/shorts/D6uo93-RcaY

ThinkNode M3 DFU Mode

To enter DFU mode:

Attach the magnetic USB cable
Hold the button for ~25–30 seconds

Ripple v9.4 for HeltecV4

2026-04-05T00:00:00+00:00

I’ve now added map tiles support for the Heltec V4 Expansion Kit.

Download

You can download + flash in one easy step using this direct link to the MeshCore Flasher target.

NOTE: there are two firmware variants now; one for existing uses who don’t want map tiles support, and a new ‘LittleFS’ variant for map tiles support.

WARNING: The LittleFS variant uses a different flash storage partition scheme, and you will lose all your settings if you switch to this one. However, once on this variant it’s safe to do future upgrades and not lose settings.

General Guide

The Heltecv4 has a UI which mostly like the other Ultra devices, like the T-Deck, so refer to the general user guide here for details.

The ‘LittleFS’ Firmware

This new variant, it carves out a LittleFS partition about 14Mb in size. So, you can drop map tiles up to about that size. This is fairly limited, but you should be able to drop some subset of your local geography for a few zoom levels.

Please see the FAQ about how to get map tiles.

Copying Files to LittleFS

There is a handy online tool called ESPConnect which makes it easy to connect the HeltecV4 via USB to your computer, then add/modify/delete the files in the LittleFS partition.

Just click on the CONNECT button at the top, select the port for your USB connection, then click on the LittleFS Tools tab:

You’ll need to be patient while it does a full read of the partition, but once done, it will ask you to click BACKUP (which is very handy), that saves the entire partition to a .bin file.

If you look below, you should then see the various files/folders in the file system. For the map tiles, just drag/drop the whole ‘tiles’ folder you have prepared on your computer. NOTE: you will see this warning if you’ve blown the size limit:

You should see the orange warning Unsaved changes after adding/removing files/folder, and once you have made all the changes need, just click the blue SAVE TO FLASH button:

Again, you’ll need to be patient as it writes the entire partition back to the device. But, once it’s done just disconnect the device, then press the Reset button on the device.

The MeshCore Map

2026-04-04T00:00:00+00:00

Origins

When MeshCore launched at the start of 2025, discoverability was a pretty big issue - that’s where the idea for the MeshCore internet map was born. Liam Cottle’s Meshtastic Map was the primary inspiration. The first version was released in April 2025 and the first nodes from the UK, Australia and Slovakia started to flow in. The number of nodes grew rapidly - we had the first 1,000 nodes within a month, crossed the 5,000 mark in summer, 10k in December and now we’re at 30k nodes worldwide.

This is how the map looked in May 2025

Basic concepts

The map was created mainly to reference infrastructure nodes, so you know exactly where other repeaters are and what radio settings they use. This was later extended to node statistics, search, filtering and basic health monitoring of the mesh.

Notable Features

Apart from the obvious map browsing and node search, there is a powerful filter that can be very useful for finding specific nodes.

Search in current map view only - useful when you’re looking for a specific node or public key prefix in your area
Only show duplicates - shows only names that appear more than once on the map, good for map cleanup

The filter menu opens when you click on the filter icon

Node freshness

Nodes updated by MeshCore Map Auto Uploader are color coded, so you know which Repeater / Room Server / Sensor was recently heard:

Color	Status	Meaning
Green	Recent	Updated within the last 5 days
Yellow	Stale	Updated within the last 10 days
Red	Old	Updated within the last 20 days
Black	Extinct	Not updated in over 20 days - will be deleted soon
No tint	Manual	Added manually, not automatically uploaded

Node freshness on the map

Clicking on the coordinates in a node popup opens a small context menu with quick links to open the location in OpenStreetMap, Google Maps or Mapy.com, as well as an option to copy the coordinates to clipboard.

Clustering zoom level

By default, nearby markers are grouped into clusters to keep the map readable. The Clustering zoom level slider in the filter menu controls at what zoom level markers stop clustering and are shown individually. If you’re exploring a dense area and want to see all nodes separately without zooming in all the way, sliding it to a lower value will expand clusters earlier.

QR code

Every node popup shows a QR code that encodes a meshcore://contact/add URL with the node’s name, public key and type. Scanning it with the MeshCore mobile app adds the node directly as a contact - no manual copying of keys needed.

Node popup with QR code and all the details

Shareable URLs

The map remembers your current position and the node you have open. The URL updates as you move around, and when you open a node popup it switches to ?public_key=... format. You can share that URL directly - anyone opening it will be taken straight to that node with the popup open.

You can also use the url in your own regional page using <iframe>, here is an example:

<iframe src="https://map.meshcore.io/?lat=47.8721&amp;lon=12.5903&amp;zoom=8" style="width:100%;aspect-ratio:3/2" frameborder="0" scrolling="no"></iframe>

Adding/Removing nodes

Adding yourself (Companion radio)

Open MeshCore app
Tap the ⋮ menu icon in the top right corner
Tap Internet Map
Tap ⋮ again and choose Add me to the Map

Adding yourself to the map

Adding a Repeater or Room Server

Open the Contacts tab in the MeshCore app
Tap ⋮ next to the Repeater or Room Server you want to add
Tap Share, then Upload to Internet Map

Adding a repeater to the map

Removing a node

Removing can only be done with same Companion radio (same public key) that was used to upload the node.

Open MeshCore app
Tap the ⋮ menu icon in the top right corner
Tap Internet Map
Find the node you want to delete, tap it and choose Delete Marker

Beyond the interface

MeshCore Map Auto Uploader will let you automatically add and update all repeaters, room servers and sensors when they broadcast an advert. That’s the main reason you can see freshness indicated by the colored node icons.

OTA Updates on nRF Devices

2026-04-02T00:00:00+00:00

Updating the firmware of your repeaters or room servers is super easy for nRF-based nodes.

1. Download new .zip

You should then see a reply, like:

OK - mac: FF:AA:BB ...

Alternatively, you can use a standalone device like the T-Deck with the Ripple firmware to enter the start ota command:

3. Connect with your phone

If you don’t have it installed already, you will need to install the Nordic nRF Device Firmware Update app, which you can find on Google Play and the App Store.

3.1 DFU App Settings

In the app, tap on Settings icon and use these recommended settings changes:

Packet receipts notification - ON
Number of packets - 8
Request high MTU (Android only) - OFF
Disable resume - ON
Prepare object delay - 0 ms
Force scanning - ON

3.2 Start update

In the app, select the .zip file you downloaded and select the Device, Then press the start button:

And that’s it!

4. Finishing Up

Once completed, logout then log back in (either with the app or a standalone device), check that the clock is correct with the clock command. If it is incorrect, just issue the clock sync command.

Also, you might want to enter the ver command, to check the firmware version is now updated.

Trouble Shooting

If the update stalled or failed, try issuing this command from phone or standalone device:

reboot

And then try the process again.

OTA Updates on ESP32 Devices

2026-04-01T00:00:00+00:00

Updating the firmware of your repeaters or room servers is super easy for ESP32-based nodes.

1. Download new .bin

Go to the webflasher and find your device, then select the Repeater or Room Server role, then latest version. In the bottom-right, click the Download button, then select the second .bin (ie. not the merged.bin!):

Alternatively, go to the Github releases page, then find the related artifact, eg. the Heltec V3 Repeater. NOTE: do not download the -merged.bin!

2. Login to repeater/room server

Using the mobile app, login to your device:

Then switch to the Command Line, and enter start ota command:

You should then see a reply, like:

Started: http://192.168.4.1/update

Alternatively, you can use a standalone device like the T-Deck with the Ripple firmware to enter the start ota command:

3. Connect with your laptop/phone

The ESP32 device should have created a WiFi access point called MeshCore-OTA. Just connect to this from your laptop (or phone), and navigate to the URL that was shown in the command line response (above). You should see a page like this:

Just take note of the ID displayed, eg the “MC Prime (Xiao C3)”, as this should be the name (and MCU type) of the node you are about to update.

Click the Choose file button, and select the .bin file you previously downloaded. You should then see a progress bar:

4. Finishing Up

Also, you might want to enter the ver command, to check the firmware version is now updated.

Trouble Shooting

If the progress bar stalled, or something went wrong, try issuing this command from phone or standalone device:

reboot

And then try the process again.
