only battery state ? about esp32_bletracker HOT 2 CLOSED

Hi @JulienNabaztag, thanks for trying my project.
BLE devices, when paired, are undetectable. For this reason it is not possible to determine their presence. In your case I assume the device was detected while it was unpaired and therefore it was possible to read the battery value which is saved for 12h before reading it again, after this period, if the device is not detected, the battery value will be -1. Alternativelly you have moved the device too far from the ESP32.
Give a try unparing the device, if it is paired, or move it near the ESP32 to see if something changes.
In order to read the others values you should implement a function similar to my batteryLevel that you find in the main.ino where, from the service_BATT_UUID (0x180F), I read the char_BATT_UUID (0x2A19) characteristic. Obbviously you will have to use appropriate services and characteristics. This link may be useful for you
Getting Started with ESP32 Bluetooth Low Energy (BLE) on Arduino IDE to understand how to use the values you extracted from the python.
The project does not support iBeacon UUID but recognizes devices only by their mac-address
