I have never had this issue before today.
Very reliable normally.
I can't sync the updates lately... I mean my windows updates when it forces me so I don't take notice of the builds. I've had 10 for a while now.
I am on Version 2004, 23.09.2020 OS Build 19041.804
Suggests I've had it for a while and therefore definitely done a few updates of GD77 since Sep last year.

Did you update the firmware ?

Umm

Just tried it on my W10 machine and I'm now getting the same error.

I'll try reverting the firmware.

I think this may actually be a timeout error.

Yep.

Its comms timeout error.

The comms speed got reduced after I fixed a serious bug with the CPU being accidental overclocked by 50% from the very beginning of the project.
(Not my original code)

Looks like somehow this has caused a bug on W10, but not on W7 or W8 etc.

I'll need to see if its also related to USB type, i.e USB 3.

Anyway, the thread message is potentially misleading

yes - all possible there.
I updated the firmware without issue. It's just the code plug write that has the issue.

I think the motorboating was partially being caused by the overclocking. But when I set the correct clock speed, the audio stopped working altogether and I had to modify/rewrite the whole DMR audio pipleline.
I didnt write all the original code, Kai DG4KLU did, but since he stopped work on the project 18 months ago, I've had to slowly re-write a lot of his original code, and there isn't much of his original code remaining.

The audio pipeline needs more work, but its going OK for now.

I have a work-around fix for this, by sleeping the thread for 1 millisecond after each block of data is sent to the radio by the CPS, but it slows down the transfers a lot.

I think I'll need to release this as a temporary fix, until I can work out why I'm getting these timeout errors with the threading and comms.

I've done a temporary fix by adding some 1 millisecond delays while waiting for the USB serial comms, which seems to have fixed the problem with the CPS with the latest firmware and the latest Windows 10 update.

Windows 7 does not seem to have these problems.

See

https://github.com/rogerclarkmelbourne/ ... 1.02.15.01

This has caused all the transfers to run a lot slower, and I will need to do a major rewrite the communications to the OpenGD77 firmware, to increase the speed back to where it was prior to this Windows 10 update :-(

ok - all fixed at my end.
yep its slower but it works and I have other radios (big brand) which are slower still.
Thanks
