I am working with Linux Mint and as far as I know when I boot the PC the bluetooth connection remains opened although you closed it the last session. So at the booting I created the script closing the bluetooth connection with "rfkill block bluetooth" so my BT connection remains always disconnected after a boot. Now I would prefer at the booting to test if my bluetooth mouse is reachable. If can be connected then connect it. If after 5 seconds it can't be connected then disconnect the bluetooth from the PC. How do I write this script?
