In case the above steps did n’t work you , we are in the same shoe . While I was about to give up on this clause altogether , I stumbled upon a Python script on GitHub calledbluetooth - autoconnect . It ’s a python script that automatically connect to all paired and trusted Bluetooth devices . However , the script is not available to establish right away on Flatpak or Apt monument . Hence , we require to manually download and configure the service .
First of all , download the zip filing cabinet from GitHub or use the following command to clone the secretary to your home directory .
Now that we have the repository downloaded we need to move the service and script to their respective emplacement before we set forth the service . In my compositor’s case , I am using systemd architecture , hence the file destinations mentioned would be applicable to distros like ArchLinux , Ubuntu , Debian , etc . In case you use non - systemd distros , kindly google your table service directories .
Once , we have successfully copied the service to the respective directories , have ’s enable and initiate the service . To do that , use the following command .

Since the machine would always strain to connect with your Bluetooth machine .

I could never get at the conclusion that whether it ’s the manufacturing business driver issue or something Linux has n’t figured it out yet .
