Ryde Receiver + QO100 Live Tune

Post by m0lte » Wed Oct 14, 2020 8:18 am

Good morning

I find that MiniTiouner is stuttery whereas Longmynd is perfect, and I'd prefer a Linux solution on receive anyway.

However, Longmynd isn't really convenient to use standalone, so I'm building a Ryde Receiver. However, IR remote control isn't particularly what I'm after either.

Just a thought, is it feasible to implement a UDP listener on the Ryde Receiver which emulates MiniTiouner's UDP control, so that QO100 Live Tune (point and click tuning) can be used?


PS we'll be running this up at Gilwell Park, UK national Scout HQ, at the weekend for a fully remote Jamboree on the Air 2020.

Hi Tom

Yes, UDP control is on the requirements list https://github.com/eclispe/rydeplayer/issues/3, but hasn't reached the top of the pile for implementation yet.

So unfortunately the feature won't be available for Gilwell JOTA this weekend. Hope all goes well.

Dave, G8GKQ

Thanks Dave. I guess my prep day tomorrow will involve scrounging a remote and IR module from somewhere then! That or cobble together some buttons from somewhere.

Many thanks

I am also using the Longmynd software on RPI4 succesfully. Works really well, but was also missing the easy tuning utility (QO-100 WB Quick tune). I didn't want to change anything in the longmynd source, so for the time being I used a different approach by installing Node-Red on the RPI4 and created a flow which decode the UDP string from the Quick Tune utility, then write the important information to 3 files (frequency and samplerate and A/B-port) and then run a shell which reads this 3 files and start Longmynd with the values stored in the 3 files. Works for me.

The Node-Red flow is simple, first split all parameters, then switch the output so only frequency and samplerate , then split again to get rid of the freq= string so only frequency is left. Write this to file, same for Samplerate, and then run the shell. See example of the shell.
If somebody wants that Node-Red flow, then I can send it.

# Start Longmynd via Node-red, by JK

freq=`cat /home/pi/freq`
sr=`cat /home/pi/sr`
b_input=`cat /home/pi/b_input`

sudo killall longmynd
sleep 1
sudo /home/pi/longmynd/longmynd $b_input -r 10000 -i 5555 -I 4444 $freq $sr &

PS, I also created a MQTT interface which publish data from LongMynd. If you are interested please let me know, This MQTT data is displayed again in Node-Red.
