I like your video and the additional information you presented. You know a lot about these Xiami devices. I own such BLE Thermometer, so I wanted to try your program sketch. Indeed it works fine - but only for a limited time, then it not only loses connection, but worse, the esp32 is aborting and restarts, a complete reset from the beginning. I combined your information with the instructions given by Andreas Spiess in Video #174 on BLE (turning notifications on and off), but unfortunately the same result, after giving some results the esp restarts with a reset and gives again some results, restarts, gives results...
Is there a forum where we could investigate these issues further and exchange our observations?

Great video, thanks! I was hoping to find something like this as I want to use BLE with the ESP32 for an electronic conference badge.

Good work.
Is the humidity value in array char at 8 and 10 position?
How do I get the sensor battery status value?

Thx, tutorial is very helpful.
Do you have code to read humidity and battery level from Mi BLE sensor?

hi, thanks you for this very informative and well documented study.
I have a baby thermometer from Xiaomi and I have tried your method for this thermometer. however, the incoming information is not the same as in your example. I did not get the result I wanted on the nrf connect application. If you have time for this, I can also share screenshots via e-mail (if you can share your mail adress with me). I would be very grateful if you could help with getting the data. Thank you very much for your interest. I wish you good work.
