Bandwidth RCP, timeouts and module disconnection

Hi.

I’m dealing with massive dropouts and missing network packets with the QL1. ( latest Companion and the lastest RCP module) when I move the faders up and down in a normal live operation pace. The module disconnects at random rate.

I’ve tried changing the metering buffer from 10ms to 1000ms without any luck, so I’m running out of ideas.

I remember facing with something like this in a software I did years ago, and the solution was moving the function to async (threaded) to let everything else keep running (gui and other processes), but… as far as I can see, nobody is having this problem, so… mmmm

Things I’ve tried: different NIC interface (motherboard and RJ45 - USB), change the RJ45 cable and increase the metering buffer. Companion in PC windows 11 and Mac M1.

The log:

Any ideas?

Hello and welcome!

I’ve never heard of a problem like this as long as the module has been in existence (many years now), so I have to think something strange is going on with your network.

Do you have any other devices on your console network? Try to simplify the setup to test only the console and computer. Use a simple (dumb) switch to connect ONLY the QL1 “Remote” connection (not Dante) to your computer.

Check the module log too, to see if there’s any error messages there. (You were showing the companion log, so open the module log instead)

Hi.

Yeah, I know how weird it sounds when nobody is having this problem. That’s why I’m a little worried.

We have some QL1, CLs, and DMs around. Tomorrow I will check it with the DM3 and another QL1. But the network was isolated, just a cable between the PC or MAC NIC and the mixer, no switches, no routing, and definitely no Dante at all.

Let me check the log of the module tomorrow as well.

Thanks for the quick answer :slight_smile:

Morning!

The module log throws error when I move any fader at a random rate. I’ve checked with 3 QL1, two with 5.90 Firmware, the other with 5.81.

debug,“[2025-08-26T06:46:35.488Z] Received: ‘OK devstatus runmode ““normal””’”
debug,[2025-08-26T06:46:35.488Z] Received: ‘OK devsta’
error,"C:\Users\RNE\AppData\Roaming\companion\modules\yamaha-rcp-3.5.10\main.js:1
(Then the chunk of the error).

Tried so far: 3 different QL1, two different computers (mac & windows), without any switch/router and different RJ45 cables. Tried with and without the streamdeck (same error).

More tests:

  • tplink dumb switch, same error.
  • TF1 works normally. I just tested the TF1 and no errors at all.
    (When the DM3 returns from a little gig today, I’ll test it too. Same for the CL3)
  • Reset the Companion config and delete all the programming. From scratch, just reading variables from the mixer, QL1 WORKS. Odd as hell. There must be something related to the functions we are using (MTX or MIX levels). Keep digging!

As a new user, I can’t upload the logs of the QL1. But I have uploaded it to my drive:

Thanks!

Please disable “KeepAlive” in the RCP settings and let me know if that fixes the issues you’re having.

Hi.

Sorry for the very late reply. Yep, the KeepAlive was it. Disabling it made everything ran smoothly. :slight_smile: Working right now with 3 QLs and a couple of DMs without problems.

Regards!
