I try to connect with an Android 10 smartphone
1 on Raspberry Pi 2 / balenaOS 2.48.0+rev1 on which I can connect in bluetooth without problem
1 on Raspberry Pi 4 / balenaOS 2.82.10+rev1 on which the bluetooth connection is systematically refused.
how to do ?
(I bought especially the rasp4 for that, I am very disappointed)
