Android Question BLE Example2 with choosing what to Notificate

[peacemaker]

Hi, All

I was updating the BLE Android example, to have a possibility to get BLE sensor info dynamically.
I have my own BLE-sensor with B4R sketch based on ESP32.

So, the updated project is attached: BLE devices can be

• scanned, chosen, connected
• read all classes manually,
• choose one characteristic of a class - just tap one line
• and set the notification to get its info on time in the log textview, it's auto opened

But strange that if the notification is started - second time manual classes read does not work, always only one first class is found.
If to disconnect and re-connect - again all is OK.

If you have some BLE device at hands that can notify - please, "try my creation" and help to debug. Maybe it is my BLE sensor is buggy...

First time - all works OK:


But if to tap "Read data" during connection and notification - trouble:

Sure, i stop the notification before re-reading.
What can it be ?
