OV control stick freezes in flight

[tatro77]

Hi

I have been testing my new Stefly OV 7-CH070 with out sensor board for several weeks. Unfortunately I get a recurrent problem where the control stick stop working after approximately 1:30 hours in flight(12,7 battery voltage).
If I reboot the system in flight the stick control starts working again.
I have installed the rotary module and noticed that the OV is not frozen when the failure occurres.
After the first time the problem occurred, I did manage to fix it after landing by unplugging and plugging again the usb connector of the control stick with the OV stil on.

I hope you can advice me how to resolve this problem.
I have tried several options:
I installed a new Stefly control stick circuit board, cables and usb connector (to rule out the possibility of a defective part).
I tried the OV image 22086 and the official (currently using 21118,XCSoar-7.4)
I tried to flash 3 different brands of micro sd cards
I connected the control stick directly to the OV USB port without any USB hub.

I have run out of ideas and could use some expert advice from you.

The full system configuration is

• single seat glider without engine
• 7" Stefly OV no sensor board.
• Stefly Rotary Module and control stick
• Lx nav S10 connected to ttys1
• Classic alarm F9 connected to ttys3

Thank you in advance.

Hi Tatro,

i had exactly the same issue in our LS8. I tried a lot of things, but nothing helped. Then one of our club member told me to change the delivered usb cable of the stefly stick with shielded USB cable. I bought a common USB extension cable and changed this cable with the delivered stefly calbe. Now it works fine!

Regards
Alex

Hi AlexThank you so much for the advice! I have tried all kinds of things but no luck. I installed the OV last Image hoping the problem to go away but had my doubts.I will install a shielded usb cable and try again. Best regards JuanSent from my iPhoneOn 12 Jan 2023, at 12:12, franke1312 ***@***.***> wrote: Hi Tatro, i had exactly the same issue in our LS8.

Well...after years of flying with the Openvario and the SteFly Stick, today the Stick remote control froze several times. Luckily I also have the rotary encoder installed, which still worked, so I could continue flying. Very weird, will do some troubleshooting soon. I have installed a new radio and a canopy strobe, so maybe it has something to do with that.

Hello. It is interesting to mention that I installed Stefly OV, the new AIR COM and Air control Display from Air Avionics at the same time. I managed to replicate the problem last season, pressing the PTT button multiple times. It has not been easy to consistently replicate the flaw. I have now switched to shielded cables for the PTT and so far it works fine. I haven't flown enough to be sure it's a complete solution, but it might be a good idea to try that or Alex's advice to use a shielded USB cable.

Juan

Interesting, I use the same setup since this season. Unfortunately I cannot easily install shielded cables, at least not for the USB cable. But at least this gives me a hint what to look for. I will probably start with using shielded cables for PTT and hope it goes away.

Well, consider the arduino boards used for shielding as well. It may be that the issues aren't connected to the cables (alone) but also to the otherwise unshielded arduino boards inside the rotary/stick controllers.

Did some minor improvements, but they did not solve the problem.

Additional observations:

• Rotary control still works after the stick stops working
• A bluetooth keyboard also does not connect anymore

I also got a log from the event where the stick stops working:
