Unbricking an ESC on Meteor75 Pro Matrix 1S using C2 interface

Unbricking an ESC on Meteor75 Pro Matrix 1S using C2 interface

I bricked one of the ESCs on the 1S Matrix AIO after unsuccessful melody write, probably because of the bug in the newest Betaflight. The configurator started saying “read failed” on it.Here’s how I unbricked it.

the process

  • to stay on the safe side, downgraded Betaflight to 4.5.1
  • follow the tutorial
  • buy Arduino nano (15元 clone is okay too, but it must have the bootloader).
  • download BLHeliSuite
  • make the C2 interface by flashing the Adruino using BLHeliSuite
  • use needles to connect the Adruino to the ESC pads
  • connect a fully charged battery
  • press read, then flash Blheli_S
  • disconnect everything
  • connect a fully charged battery, connect USB port to the computer
  • connect-disconnect using Betaflight configurator
  • connect using ESC configurator
  • reset settings, write settings
  • flash Bluejay one by one
  • reset settings, write settings
  • adjust the settings from before (especially motor direction), write settings
  • write melody
  • disconnect everything
  • restore the conformal coating
  • reflash Betaflight to the newest version, restore the config
