Characteristic doesn't receive value
I use ESP32, got BLE working correctly and send periodically Notification Values.
 
On a mobile with BLE Scanner: The sensor is seen, periodically NOTIFY update values are received.
On the raspberry: Sensor is connected, Service and Characteristic is "connected".
In the Homekit (also tested in the EVE App): Sensor is seen, correct service and characteristic. I can start "identify" the sensor with positive response. I see the action "Identify" in the Raspi log too.
 But ... never get values or value updates. I would expect the same behavior, like the BLE Scanner do. I'm confused. please help.
