[A64] Bluetooth service not activate on restart

[vikas]

Hello,

I am using A64 package "A64-OLinuXino-bionic-base-20201008-215447.img.7z", and recently upgraded and updated firmware. Now when I restart, bluetooth service, sometimes it fails to be active. Logs:

I also tried systemctl restart bluetooth, systemctl enable bluetooth, but that also not activate service.

After power off and power on, the bluetooth service on start, activate.

My requirement is bluetooth service should be ON for 10 hours in one go and activate on every software reboot(may be no power cycle).

Regards,
Vikas

Not sure if it is isolated issue for our hardware or general Linux bug, it seems to be present in a lot community threads, for desktop computers too. Will investigate.
