GDBus Error on new discoveries

[giuseppemr]

Good morning everyone,

I am actually using tinyb library for Java on a Raspberry Pi 3+ to scan for BLE devices.
After a period of time (it can be minutes or hours), new scans make the system blocks in a non recoverable loop with this error:

2020-10-09T08:27:16,310 [Thread-896] ERROR o.e.k.i.b.BluetoothLeAdapterImpl - Stop discovery failed
tinyb.BluetoothException: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name :1.7 was not provided by any .service files
        at tinyb.BluetoothAdapter.stopDiscovery(Native Method)
        at org.eclipse.kura.internal.ble.BluetoothLeAdapterImpl$BluetoothFuture.run(BluetoothLeAdapterImpl.java:266)
        at java.lang.Thread.run(Thread.java:748)

I tried to stop and restart my program, restart the bluetooth service, but the only solution is to completely reboot the system.
Any help is really appreciated. Thanks.

@giuseppemr check bluetoothctl CLI tool for Linux
Maybe Your bluez version is incompatible with tinyb
