Langstone not starting up

[g8gtz]

I have just rebuilt my system and although Portsdown works, I cannot get Langstone to start.

It goes through the very long motions (due to Pluto reset), the blue flash screen appears but goes back to Portsdown. Eventually, I suspected that there was an error message flash up before the reset but I could not read it in the time it was there. I then filmed it on my iphone and went through it frame by frame to discover it said Lang_tx.py failed to load. Check your sound card config.

There is a white ebay sound dongle plugged in which Langstone has worked with before and Portsdown info screen reports:

So any ideas?

Also, can the error message stay up for a longer duration please

Hi Noel,

The error message remains visible on a standalone Langstone. It’s only when using with Portsdown that it disappears. I will see if I can add a delay.

You could try running the set_sound command from the Langstone directory to check and configure the sound device. However that message can occur for many reasons. It just means the Lang_Tx task failed to start.
See the wiki for other diagnostics.

Thanks Colin,

I did the set sound command and it saw the dongle and said it had been set for Langstone.

I then did all the other tests such as Pluto and Mouse which it passed but still does not load into Langstone......

Ok Noel.

Have you read this topic? viewtopic.php?f=129&t=7242&start=10#p26817

M5TXJ was having a similar problem. It turned out it was because the Langstone install script in Portsdown takes a long time and he was selecting it more than once.

I ended up using Winscp file manager https://winscp.net/eng/index.php to log in to the Pi and deleted the Langstone directory.

I then used the install Langstone option in Portsdown and everything works again.

Hi Noel,

That’s good news. Glad you got it working.

I use FileZilla for my remote file transfers.

Folks, I have just built my portsdown 4. It works very well with my Pluto.
I want to use with Langstone. I installed. But it does not start up. After a longer load it jumps back to the Portsdown menu.
What firmware shall I use in Pluto for Langstone?
What main mode shall I select:
DATV or Passthrough (SDR Console,...) ?
should I set:
RTMP or UDP ?
My current version is 0303 by F5OEO. Is this a proper version for Langstone?

Langstone uses the Pluto in its original mode, it does not need the F5OEO firmware.

It does however work with the older ‘for the brave’ version of F5OEO which is the same one recommended for Portsdown.

I notice that recent versions have added the option to switch the mode of operation. I have not tested this but I would think that it might need to be set to Passthrough. That might cause problems in a combined Portsdown/Langstone system as there is no easy way to switch the mode.

Your Portsdown will check the version in Pluto for you. Somewhere on menu 3 IIRC.
