MeshCore on the AIO v2: YAMPA, tui-meshcore and meshcore-uconsole
MeshCore has no Linux-native node firmware, so the community built on pyMC_core: guax's YAMPA packet analyser and TUI chat client, and cwill747's GTK app.
What it takes
- Software only
- Config change
- Purchase required
Difficulty 1 of 3 - easy.
Details
vileer's answer in October 2025 was that MeshCore did not support Linux-native devices; by February 2026 guax had a working stack on the AIO v2's SX1262 through pyMC_core and the pyMC_Repeater project. The board needs two extra lines in the sx1262 section - use_dio3_tcxo: true and use_dio2_rf: true - which interlock has since upstreamed as an AIO v2 preset (pyMC_Repeater PR #99). On top of that: YAMPA (GPLv3), a React front end over a Python WebSocket server started with server.py --radio-type uconsole; tui-meshcore (GPLv3, Textual), pip install -e . then tui-meshcore, for channels and direct messages; and cwill747's meshcore-uconsole, a GTK network analyser with hardware presets that installs from his APT repository as meshcore-uconsole.
All three share the radio, so stop meshtasticd first - LOCOSP's python-periphery errors on a CM5 were exactly that. cwill747 confirms the AIO v1 needs the same two settings.

Run a Meshtastic node on the console itself: meshtasticd drives the AIO's SX1262 over SPI, with the graphical MUI, the web UI or the Contact TUI client on top.
On Rex's images a single apt install gives you SDR++ for the AIO's RTL-SDR or a USB dongle; his AIO package adds the sdrpp-brown fork.
Two receivers, two recipes: the 4G card's GNSS via AT+CGPS on /dev/ttyUSB3, or the AIO's GPS on the serial port (/dev/ttyS0 CM4, /dev/ttyAMA0 CM5) at 9600 baud.
The AIO's PCF85063A keeps time off-grid once the right overlay is in config.txt - and on a CM5 the built-in fake RTC has to be switched off first.
Rex's AIO package ships readsb and the tar1090 map as a disabled service with a menu launcher; Intercept or a hand-built dump1090 are the alternatives.
HackerGadgets' MIT-licensed CLI and tray tool toggles the AIO v2's GPIO-controlled power rails (GPS, LoRa, SDR, USB) so idle radios stop draining the battery.
