Support for new chips like ESP32-C6

[AlexGadd]

From what I understand, chips like the esp32-C6 should be capable of becoming an "AirTag", but I don't currently know enough about compiling this software that I could easily make changes to the code or even understand the limitations to be able to test effectively. Does it seem likely that these devices could be supported? If so what could I read up on if I wanted to contribute? I basically want to know where to start

I was able to use the ESP32-C6
idf.py set-target esp32c6
idf.py menuconfig
Enable Bluetooth
Disable Bluetooth 5
Enable Bluetooth 4

Also, set the partition table to Custom (partitions.csv) and edit it as follows:

# Name,   Type, SubType, Offset,   Size, Flags
nvs,       data,  nvs,     0x9000,   24K,
phy_init,  data,  phy,     0xf000,   4K,
factory,   app,   factory, 0x10000,  1M,
key,       0x40,  0x00,    0x110000, 4K,

Then build and flash:
idf.py build
idf.py flash

Next, take the public key from the OpenHaystack app and decode it into a binary file:

echo "public_key" | base64 --decode > key.bin

Finally, write it to the custom partition:
parttool.py write_partition --partition-name key --input key.bin
