Trouble connecting Beocreate to Sigma studio

None

Hello, I cannot get my Beocreate/RPi to connect to SigmaStudio.

In sigmastudio, after connecting for the first time to RPi, there are no errors, and it seemingly works fine (click 'link compile download' and it shows 'Active: downloaded' on bottom right of screen.) I'm using the example program downloaded from here.
But if I try to use any sliders or write to EEPROM I get following message.
'A TCPIP communication failure has occured. *Try connecting again.'

What to do? I'm (trying) using the board for speaker crossover building.
The board seems to be working since there is sound coming through, if the board is connected to a audio source by toslink. Also SSH connection to RPi through PuTTY is working fine.
I'm using Raspbian stretch lite. I haven't worked with Raspberry Pi before.

I used 'simple installation on raspbian' as instructed here.
I also tried installing dsptools, but same error always pops up.

Thanks for answers

Did you configured the correct IP address in SigmaStudio? The IP address in an example project is most likely not the IP address of your RPi.

Yes, I did change IP address and port number in sigmastudio to the same that I use for controlling the RPi through SSH.

First make sure, you're using DSPtoolkit instead of the older daemon. Then check that you can connect to DSPtoolkit from command line.

Use

dsptoolkit servers

to check if the server is running fine.

Running the installation script returns following, with some errors towards end:

So apparently the server doesn't get installed? 'dsptoolkit servers' returns nothing:

Hi,

you should run the installtion as root. First become root with

sudo su -

Then run the installation script again.

Best regards,
Daniel

I ran the installer as root, but seems like same errors are present:

Ok, start sigmatcp now and check the status:

systemctl start sigmatcp
systemctl status sigmatcp

Looks like you did not reboot after the installation as SPI is not active. Check if SPI is enabled in /boot/config.txt and reboot then.

Daniel

The SPI was not enabled, so I manually enabled it and rebooted, but still giving me (different) errors:

Ok, this looks like a bug if no profile is installed. We need to look into this to fix it.

Hi Janne,

I'm trying to look into this, but I need more debugging information. Can you please run the following command and post the full error output:
```
/usr/local/bin/sigmatcpserver --alsa
```

Ok, I think, I found and fixed the problem. Try upgrading dsptoolkit using

sudo pip3 install --upgrade hifiberrydsp

Then restart the service with
```
sudo systemctl start sigmatcp
```
Does this work?

Daniel

Great! The server seems to be running now, but the original problem seems to be still there. This is what I get now:

This is fine. If you try to start the server again if it is already running, you will get the error message shown above. So on the Raspberry Pi side, everything seems to be fine.

What exactly do you do to write to EEPROM?

Ok, nevermind the last post - it seems that the connection is working properly after all :)

I had tried the wrong port number on Sigmastudio. On Github there is some talk about port 8089, but seems like I need to put 8086 after all. Now in sigmastudio there are no connection errors and the example project controls work.

Thank You a lot, Daniel for helping!

Best regards, Janne
