btmon output when the mouse "connects" but not moving

My Bluetooth LE mouse (Rapoo MT750) doesn't move when it's turned off and on again. The problem is that it's shown as connected but the pointer won't move. The mouse itself (reading from LED) doesn't think it's connected.

The mouse works if I disable/re-enable bluetooth (using laptop's key binding), or simply send a "pair" command in bluetoothctl. The pair operation here will always timeout, but the mouse correctly moves right after sending the command. The pair command will succeed after a second try (after the first timeout), but it doesn't fix the problem (shown as unpaired after reconnecting).
