Confirming C6 can be made to work

[karantza]

Hi! Just wanted to confirm that I am able to get Bermuda working using my C6 boards (specifically, these DFRobot boards), since that was mentioned in the wiki as unverified. I had to use a newer version of esp-idf, even with the latest esphome, or I'd get compile errors. But with these versions it's good.

My data is pretty noisy with lots of gaps, but I read that's a common issue. I may need to play with the timings more. But it does technically work.

My relevant esphome config, mostly borrowed from the example C3 config (note, I might not need all those platformio overrides anymore, I haven't tested removing them recently):

esphome:
  name: $devicename
  friendly_name: $friendlyname
  platformio_options:
    board_build.f_cpu: 160000000L
    board_build.f_flash: 80000000L
    board_build.flash_size: 4MB
    build_flags: "-DBOARD_HAS_PSRAM"
    board_build.arduino.memory_type: qio_opi


esp32:
  board: esp32-c6-devkitm-1

      then:
        - esp32_ble_tracker.stop_scan:

I did something similar for my C6 that I purchased from aliExpress a while back.

I created a PR to merge in my C6 config...before I even looked at the issues tracker here. Got too excited about the fact my config complied and appears to be working...My bad haha.
