Quick look at an Aiyato CozyLife Homekit bulb I bought in November 2024 and forgot about. https://www.aliexpress.com/item/1005006367930047.html
C37 homekit module - I had to de-can it to check the chip. Couldn't see much about it Googling - ESP8684H2
It's a DOIT (Doctors of Intelligence & Technology) ESPC2-05 module (datasheet attached)
TX0 log at 74880 baud:
With IO9 low:
esptool chip info
like other Aiyato/CozyLife ESP devices, this is not flash encrypted or secure boot enabled
flash backup
flash 2mb ESP32-C2 OpenESP32C2
OpenESP32C2 initial boot
And with GPIO Dr PWM channels are quickly identified
