BLE CBPeripheral UUID unique per ESP32 chip?

Postby ScottyBoy » Mon Jul 18, 2022 10:09 pm

We are deploying with full ESP32 and ESP32-M5 chips, using all the features (BLE, WIFI, MQTT, APmode, etc).

But since the BLE services need to have known names and services, all the UUID's under our software control are the same.

In discovery of BLE services, there is a UUID that looks unique per chip. In Apple, this it the CBPeripheral UUID.

My questions:
  • is this value available to the ESP chip and our software?
  • is this value unique and non changing for each chip?
My plan is to use this UUID and after I find out what device it is (a name we provide), or I'll name them myself so in the future I can look for names that I've equated to UUID's of the chips.
