Esp32 in iOS battery widget use HFP Command AT+XAPL

Postby schluesselmeister » Mon Apr 29, 2019 2:06 pm

I build a wearable based on esp32 witch connects to an iOS app. It would be great if my customers could see the current battery level in the default iOS widget. To do so, you have to implement the custom at-command „HFP Command AT+XAPL“.
In Detail it is described here: 13.1 page 66:

Did anyone implement this? Or does this only works for bluetoooth and not Bluetooth LE?

Thanks a lot
