This is an ESP-IDF based project which collects some sensor data over i2c, encodes it using the BTHome format and sends it over Bluetooth.
It is currently working, with the 3 sensors visible in Home Assistant.
The project uses the standard ESP-IDF build system. I personally use the VSCode addon to compile and flash to my device
The SDK config targets a somewhat new revision of an ESP32. I flash specifically on an Unexpected Maker TinyPcio.
Bind key encryption is now supported.
Modify main/config.h to set ENABLE_ENCRYPT to true (it defaults to this) and configure your hexadecimal
bind key value. This is the same string Home Assistant will ask for.
Contributions with new sensors, bug fixes, etc are happily accepted. The project tries to follow the git flow naming, so naming branches feature/ or bugfix/
will help make it clear what its for. If you use git flow, feature branches will be based on develop by default. Otherwise, please base your branch on develop
when creating it.
Along with this, it could be useful to only send some advertisements infrequently. I doubt the device name needs to be sent every minute, for example. I'm unsure how Home Assistant would treat this though, it may mark the sensor as unavailable.
