I managed to succesfully pair my Raspberry Pi Zero 2W with my android phone via bluetoothctl but I cannot get it to connect on startup.

If I issues this command in terminal it connects with tethering fully working with an IP so i can ssh in via my phone.
sudo bt-network -c MAC nap
I tried getting this going via a script using cron but still the same it connects and then disconnects straight away.
cron command
@reboot sh /usr/local/bin/blue.sh
script was
#!/bin/sh
sudo bt-network -c MAC nap
I also tried system which works but again it disconnects 2 seconds later.

I have also tried this way from the post below but no IP is givena nd tethering doesnt work either.

Tethering isnt massivly important as I will only be logging in to issue shutdown commands and to stop kismet any help is greatly appreciated.
