Bluetooth Toggle seems to swicth back on / after flicked off

[Nora No]

I have the opposite problem, mine won't stay on.

Ubuntu 16.04 from 2020-07-04
No SIM
WiFi works, verified all hardware switches ON, including switch 2
Bluetooth does not turn on at start.

In Ubuntu Touch, I toggle Bluetooth to ON, it stays there for 30 seconds, does not recognize any device, not discoverable, then switches back to OFF automatically.

Is there a trick to this?  Out of the box Bluetooth not working.  I have also tried disabling WiFi (software).  Result is the same.  Will a SIM card be required for Bluetooth to work?  Or do I need a software package?

OK, update: after reboot, bluetooth working with Sony WF-1000XM3, but no WiFi.  Either bluetooth OR WiFi will work, but not together at the same time.  Hardware specs say both, but the specs never said "at the same time" 

Also, now Bluetooth software toggle will not stay off, same as other posts.

Give a try to :

Code:

sudo service bluetooth start
