That shouldn't happen, do you have the bluetoothd logs of that? Also make sure you don't have Cache=off: https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/src/main.conf#n83 By default bluetoothd should always cache attributes, but there perhaps you either disable it or the device is sending service changed which invalidates the cache, though we don't actually discard the cache but attempt to check if the services have really changed. > Thanks in advance > Miguel -- Luiz Augusto von Dentz
