PiSound App Won't Connect

So after upgrading my version of MODEP to the latest release for some reason I can no longer connect the PiSound app to my Pi4 running MODEP. I pressed the button 1 second to make it bluetooth discoverable and it blinks continuously for a few minutes. On my phone I click “Scan” and it’s never listed in the available devices. Anyone else seeing this?

You can try running sudo bluethootctl and see what’s going on when you enable discoverability. It should show something. Alternatively, you can enable discoverable mode by additionally executing discoverable on while running in bluetoothctl. Exit with quit command.

Let us know if you see any errors (or nothing at all) there.

So I finally got around to testing this. Here’s the output of bluetoothctl:

patch@patchbox:~ $ sudo bluetoothctl
Agent registered
[CHG] Controller DC:A6:32:30:33:32 Discoverable: yes
[NEW] Device 58:24:29:89:A8:DE Pixel 5
[CHG] Device 58:24:29:89:A8:DE Connected: no
[CHG] Device 58:24:29:89:A8:DE Connected: yes
[CHG] Device 58:24:29:89:A8:DE Connected: no

So the “NEW” is when I tried to connect to the RPi with my Pixel 5. Then almost immediately it changed to “Connected: no”. I tried connecting again and it showed “Connected: yes” with an almost immediate change to “Connected: no”.

I will also post the screenshot of my phone.

Here’s the screenshot from the phone.

When the flashing lights stop on the pisound MODEP is no longer listed as an available device.

On other test here. In this case I’m trying to pair my Dell Latitude 7210 tablet to the RPi:

patch@patchbox:~ $ sudo bluetoothctl
Agent registered
[CHG] Controller DC:A6:32:30:33:32 Discoverable: yes
[CHG] Device F8:5E:A0:0F:71:EC Connected: yes
[CHG] Device F8:5E:A0:0F:71:EC Connected: no
[CHG] Device F8:5E:A0:0F:71:EC Connected: yes
[CHG] Device F8:5E:A0:0F:71:EC Connected: no
[bluetooth]#

Same result, it connects but then immediately disconnects.

Does dmesg report any errors soon after the connection attempts?

@Giedrius after a connection attempt there are no new messages shown in dmesg. Including the output here if that helps.

What output do you get from bluetoothd --version?

Try checking out the bluetooth logs:

journalctl -u bluetooth -f

Also, try adding --experimental flag to bluetooth service as described here: Install Bluez — Bluez documentation (reboot after modifying the .service file)

@Giedrius I will try this soon.
