Not urgent as no longer a problem but…
I have been using a RPi with DAC hat as an headless sound only player for music every day. It connects by wifi to my relevant subnet and is in a fixed location in same room as wifi AP. It had been working without problems until a couple of days ago when the device, which is normally seen as a renderer on my control point, was no longer evident. I assumed some glitch on my network which had been turned off for maintenance so rebooted the RPi but no joy.
I connected a keyboard and screen and checked and some upgrades were suggested so upgraded and checked my control point and all is now OK.
Questions:-
I would like to understand why my system failed. I thought it had been set for auto updates but whatever I had set didn’t seem to do what was required. Could an auto update have been cause of loss of wifi connection?
After the upgrade I had a few error messages:-
Failed to start Raspberry Pi bluetooth helper. See ‘systemctl status bthelper@hci0.service’ for details.
This tells me it can’t init device hci0: Operation not possible due to RF-kill (132).
What is this about please and do I need to change something?
My second question concerned an error which appeared during the upgrade. I no longer have the info on screen but it concerned a problem with apt repo? Is any of this connected to my system failing?
Just wondered.
