Rak4631

Is this bug report about any UI component firmware like InkHUD or Meshtatic UI (MUI)?

  • Meshtastic UI aka MUI colorTFT
  • InkHUD ePaper
  • OLED slide UI on any display

Firmware Version

2.7.5 - 2.6.13

Description

Tried two different boards (host - mcu/radio), same ethernet+poe (even without em)

Firmware built locally and uploaded by dfu.

After a few days of correct operation the device stops communicating with the mesh, from the logs the errors are about the radiolib error -7.

RadioLibInterface.cpp:425 (state = -7, see logs)

using target rak4631_eth_gw (but also tried the plain version)
