Hello, I have a bt 4.2 mouse that has a battery service, but no battery attribute visible in Bluez, Rapoo m550 using YiChip 1201. Is it even hypothetically possible that a device can have a battery service, but no battery attribute? This is what I see in my syslog Oct 3 15:07:38 xps bluetoothd[1837]: No cache for ED:8E:0E:DF:E0:B8 Oct 3 15:07:38 xps bluetoothd[1837]: BATT attribute not found Oct 3 15:07:38 xps bluetoothd[1837]: batt-profile profile accept failed for ED:8E:0E:DF:E0:B8 Oct 3 15:07:38 xps bluetoothd[1837]: GAP attribute not found Oct 3 15:07:38 xps bluetoothd[1837]: gap-profile profile accept failed for ED:8E:0E:DF:E0:B8 Oct 3 15:07:38 xps bluetoothd[1837]: input-hog profile accept failed for ED:8E:0E:DF:E0:B8 Oct 3 15:07:39 xps bluetoothd[1837]: bt_uhid_send: Invalid argument (22) Oct 3 15:07:39 xps bluetoothd[1837]: bt_uhid_send: Invalid argument (22)
