Hello,
I have searched a lot but I can't find something about this.
I wanted to get some phone informations like the battery level and cellular network strength to add these informations to my little screen in my car, who uses an ESP32.
Maybe i can't use BLE for this, I can use Bluetooth classic if needed.
How can I achieve this ?
Thanks !

Signal strength (RSSI) is available through BLEClient::getRSSI (you can also get this in discovered devices).
