read the rssi from the sensor 

sometimes it is hard to find out why a sensor sends no data
with the rssi you got a value of the BLE signal strenght
and can optimize the location of the sensor or the ESP32

if the rssi got worse over time the battery could be the problem

rssi monitoring is a must have feature for radio signals :-)
