Pisound App fails to connect via Bluetooth

Hello there !

I just bought a pisound, and i’m very happy with it, all is working very good except the mobile app.

I already try a lot of things (i’m not a programmer but i know some tricks as long as it is 20 years i use linux).

So what i try :

  • standard procedure
  • fresh install with no update
  • fresh install with all the update (apt get update && apt get upgrade)
  • on a fresh install, make the change in the bluetooth.service to avoid the ‘Sap driver initialization failed’ error
  • try little others things without success (reinstall pisound, restart the phone, starting by pairing the phone then make the update on the pisound, restarting pisound, try to control manually the bluetooth with bluetoothctl, try to save the /usr/bin/pisound-ctl, try to use a monitor with HDMI cable , etc etc … )

I can pairing the pisound with my phone on a fresh install without module and update, but the app don’t see anything (the circle is turning and turning …). The app got all the authorisations, it can make what it want ! When the pairing works, it says that it is for sound. And when i update the pisound (apt update && apt upgrade) i can’t pairing anymore.

Modep works as expected, i can make some pedalboard and use them, the sound is very good.
I don’t try Orac because i want the app to work before i try something.

So i’m really out of idea and i really want the app to work as i want to use ModeP (thanks a lot the modep Team !) and Orac (Thanks a lot the Thechnobear !)

So here is my config :

  • samsoung A40
  • android 11 with all the update
  • raspberry 4+ 8go

and here is the result of the commands :

apt show pisound-ctl

It would be fantastic if the app could work, so here i’m waiting for your help !!
Let’s make it working together !

Thanks a lot the Blokas Team, this is really a nice hardware !!

cheers,
jubal

Mmmm i just that this topic is mark as resolve maybe i start an another one, let me know what you prefer.

and i forgot this command

sudo systemctl status pisound-ctl

Is this the entire log?

This line seems fishy:

Mar 23 17:10:16 patchbox bluetoothd[702]: src/profile.c:ext_start_servers() RFCOMM server failed for Headset unit: rfcomm_bind: Address already in use (98)

It may indicate a conflict between Pisound CTL and some audio headset?

Are you using any other Bluetooth devices with the Pi?

I’m having the same issue today
Upgrading my pisound to RPi4

  • fresh install
  • updates via the patchbox terminal app
  • BT device can be seen by PC and Smartphone when enabled, but not by pisound app

Something weird in the log, the date was wrong at first. I tried connecting from outside the app this might be visible in the log. The pisound app did not discover the RPi4 with Pisound:

I have the same line in my output. No other devices connected, also not to my smartphone.
I even tried connecting with a fresh smartphone that never had any other Bluetooth device connected to it. Same result

I got rid of the SAP (SIM Access Protocol) error by disabling that in the bluetooth service, but it does not seem to be related

This issue though seems to be related, but I tried everything mentioned there without luck

I also manually enabled “discover nearby devices” as the app did not ask this permission… but still no luck

What is the output of lsb_release -a?

I tried reproducing the problem, but it’s working just fine for me.

I do receive some of the same errors in bluetooth.service journactl log, but not the RFCOMM address is in use one:

So the above log lines don’t impact operation of pisound-ctl.

Yes, tanks for the answer ( and sorry for the Multiple reply i made in the other thread)

I give you the output this evening

Thanks again !

I wiped SD card again, did everything without updating again. Just to test if the stock OS image would work
then I switched to the non RT-kernel, just to test, but I get the exact same issues
I then switched back to the RT kernel (on RPi4 -4Gb)
Then I updated again…

This is my output

Mmm now you are pointing this, i see that it was not the entire log,
So here is the full result :

And i’m not using any other bluetooth device.

and here the result of lsb_release -a

thanks for your help !

By the way, every time you reflash the OS on Raspberry Pi, it gets some new system finger print, making previous pairing remembered by your phone no longer valid.

Make sure to manually unpair (forget / remove the device from the Bluetooth devices settings screen), before trying to pair via the app again.

So far I haven’t been able to reproduce the problem.

At the same time I’m working on updating the Patchbox OS image, so it would make sense to focus on getting this working on the new image, once it’s out, as there’s going to be big changes to various software and drivers anyway.

Ok, if you can’t reproduce the problem, i understand that you can’t help us !

And yes i made the unpair/pair trick a lot of time, but doesn’t change anything.

And for sure if you are working on a new PatchBox OS image, don’t worry about my problem, like you said, we will see this with the new image. I just hope it doesn’t come from my phone !!

So thanks for your help, and have a good day !

I tried multiple phones, including one that was not paired before. I “forgot” the pairing before I tried again

If it could help, I could set up remote Ssh access to my pisound

I installed the new Patchbox OS image.

Same behaviour

I can see and pair from the bluetooth settings of my phone, or from the patchbox OS bluetooth icon in the taskbar(topright)
but not from the android app

What happens exactly when you attempt to pair through the App?
