I use the glib D-Bus interface to connect to a BLE button. This works great some times but I regularly get this connection error: GDBus.Error:org.bluez.Error.Failed: Software caused connection abort, 36 The debug output in bluetoothd is: bluetoothd[17071]: src/device.c:device_set_auto_connect() 80:E4:DA:70:07:A7 auto connect: 1 bluetoothd[17071]: src/device.c:device_connect_le() Connection attempt to: 80:E4:DA:70:07:A7 bluetoothd[17071]: src/adapter.c:add_device_complete() 80:E4:DA:70:07:A7 (1) added to kernel connect list bluetoothd[17071]: src/adapter.c:connected_callback() hci0 device 80:E4:DA:70:07:A7 connected eir_len 0 bluetoothd[17071]: src/gatt-client.c:notify_client_ref() owner :1.2517 bluetoothd[17071]: src/gatt-client.c:notify_client_ref() owner :1.2517 bluetoothd[17071]: src/device.c:att_connect_cb() connect error: Function not implemented (38) bluetoothd[17071]: src/device.c:att_error_cb() Enabling automatic connections bluetoothd[17071]: src/adapter.c:dev_disconnected() Device 80:E4:DA:70:07:A7 disconnected, reason 0 bluetoothd[17071]: src/adapter.c:adapter_remove_connection() bluetoothd[17071]: plugins/policy.c:disconnect_cb() reason 0 bluetoothd[17071]: src/adapter.c:bonding_attempt_complete() hci0 bdaddr 80:E4:DA:70:07:A7 type 1 status 0xe bluetoothd[17071]: src/device.c:device_bonding_complete() bonding (nil) status 0x0e bluetoothd[17071]: src/device.c:device_bonding_failed() status 14 bluetoothd[17071]: src/adapter.c:resume_discovery() What worries me is the connect error: Function not implemented (38) line. I'm on commit 1b9e48f4c2b98ea88e43bd493c098dcca822a1d0 Is this a potential bluez bug? When I manage to connect to a button, the output is as follows: bluetoothd[17071]: src/device.c:device_connect_le() Connection attempt to: 80:E4:DA:70:08:9E bluetoothd[17071]:
