GX12 momentary switches SG lock into on position and all other buttons stop working

Current Behavior

Twice now with two different models (Pumpkin and Diana Jet) my GX12 has got into a state where buttons/switches no longer work and it appears to be in high rates mode. I have these models set up so that when I press momentary shoulder switch SG I get full throws on my ailerons. Usually they only go to 40%. This allows me to do sick quick rolls, but control my plane normally when not being fancy.
Last week after doing some super fast rolls using SG the plane remained in high rates mode and the switches stopped working since I put it in RTH and it carried on flying under my control, not RTH. Luckily I still had control, but no switches worked. The same thing happened today with my pumpkin, I've attached the model file since it's simpler than the jet which has a flight controller.

I managed to bring this one down somewhat safely when I worked out what was going wrong and took a video of the radio sending full throws and the switches not working. It says "excellent" when I press SG, but it no longer did it in this weird stuck state. Then, leaving the plane powered up I power cycled my radio and it went back to normal mode and after connecting I only had 40% throws again until I press SG.

This might be somewhat related to #5810 but it's not quite as serious and I've had a new motherboard and I'm running latest firmware since that happened.

I'm running the latest 2.11 RC 4

Expected Behavior

releasing SG should put my plane back into 40% throws mode and the switches and buttons should still work.

Steps To Reproduce

1. fly around and press SG and do super cool quick rolls.
2. at some point (not every time) it might get stuck in high rates mode (SG down) and it will no longer play track that says "Excellent"

Ouch! I've not in a position to watch the video atm, but the crux of this is SG stopped responding completely? Can you list what other switches haven't worked in this state also, to see if there is anything common to those. However, I suspect if one stops working, they all stop, ideally (i.e. fixable) due to a firmware/timing bug.

[arkarkark]

I'm pretty sure they all stopped working. but for sure the momentary SG and the 3 position SB (since I use that for RTH)
next time I can confirm that they all stop working. Thanks for the quick reply.

[arkarkark]

I also use SH to blip 100% throttle so next time I fly I'll be playing these buttons like an accordion to try and trigger this bug and collect more data.

[arkarkark]

not sure if it's worth mentioning, but I ram the same setup on my jumper t-pro (and t-pro v2) and never had this problem. I'm not stoked with how squishy these gx12 buttons are and wonder if it's debouncing logic causing it? just a totally uninformed guess, but you mentioning timing brought it to mind.

[philmoz]

You said you replaced the motherboard - might be worth double checking all the cables and connections are properly seated.

[arkarkark]

yah, double checked them. the switches work again after power cycling the radio so it's not that. I spent today (6+hours) with the radio on and pushing the shoulder buttons and pretending to fly and couldn't reproduce it, not the whole 6 hours, but many times over that period. so next up is to try with it connected to a receiver so it's getting telemetry data back. maybe that was causing the timing issue.

[arkarkark]

This happened again twice today. Luckily I was able to land both times since I was flying my dumb wing and the only behavior was full throws. I took another video if you want to see it I can share it. I also have the sdcard log file too if that might help.

I tested more and indeed no switches on the top or the radio work (SB -> SG) they don't do anything and the indicator on the screen showing their state doesn't change too. and SG the momentary press button that behaves like it is locked down remains in the pressed state on the screen even though it is not being pressed.

The 6 color led buttons just below the power button also do not work. I have some of them call a specail function and they do not do that.

The trim buttons DO work. as do the MDL, jogwheel/enter and RTN, Page> page< (I didn't check tele or sys)
The power button also worked to turn the radio off and when I turned it back on everything worked as usual and expected.

It is not just this model, I have another model the same thing has happened on. that one crashed because my return to home switch change didn't get picked up.
I've never had this problem with the same models on my jumper t-pro (v1 and v2). I'm close to switching back to that as I'm losing faith in this GX12.

[arkarkark]

I managed to reproduce this at home while not flying today. I verified that the pots and sliders (even the ones on the button/switch breakout board) still work. I also switched models and then back it still had the same problem. I also went into sys->hardware and changed some of the buttons from toggle to 2pos and then back that did not fix the problem either.
I'll try and work out a quick way to get into this state so I can help verify a fix or collect more data for you. I could even run a special build which would collect data from some sys or model menu item if that'd help.

[arkarkark]

This is still happening to me on a regular basis. Not every single flight but at least one time each day that I fly. It has caused quite a few crashes and I'm worried I'll end up losing a plane because of it.
Is there anything I can do to help track this down?

I'm sure I'm triggering this bug because I press SG a lot, but that doesn't mean other users won't come across it and also lose control of their models. The big issue is, once this happens the switches stop working completely and so you can not put your model into RTH or some other failsafe, whatever you wanted to happen momentarily with the switch is now happening all the time and there is no way to stop it or go back to normal unless you have the presence of mind and time to turn of your transmitter and turn it back on and hope you reconnect with your model.

@arkarkark since you did not mention it: did you update to 2.11.1 or are you still using 2.11.0-rc0?

[arkarkark]

I thought I was, but I was only running 2.11-rc4
I just flashed 2.11.1

[raphaelcoeffic]

I thought I was, but I was only running 2.11-rc4 I just flashed 2.11.1

Could you please try with the builds from #6321 ? Or with the nightly build (same kind of changes already there)?

[raphaelcoeffic]

I made another PR that should help solve the issue here: #6325
