Re: Using whitelist with resolvable random address
You can see the UUID on scanning, just like you can see the mac.

The problem with it is, the MPL software is on your host processor, which means any missing gyro data can mess the whole algo. Also, it is VERY sensitive to mag calibration, if it is not calibrated correctly, your reading w...

Re: Gripes on ESP32/ESP-IDF
Also, just for the record, the FreeRTOS drivers for the ESP32 are amazing, this is the main reason I love this chip. The ESP-IDF is reliable and makes life easy for 99% of applications...
