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

2.7.16

Description

If I enable debug mode (Security->DebugLogApi) then the device doesn't work well over bluetooth or serial. The serial port lines are mixed with binary data.

Trying a "meshtastic --info" reports empty preferences.

The only solution is to erase and flash again.

Relevant log output

@viric what do you mean by enable debug mode? Is there a specific config setting?

Yes, it's the setting under Security. "debugLogApiEnabled". You can see in the Android app as well. Sorry that I wasn't specific enough.
