Beta 35 with Arduino hangs when connecting to FS2020

[bartroozendaal]

For full transparency: I did the following...

1) Reflashed the Arduino

2) Updated the script to no longer handle the avionics, but only the essential functions in the Cessna 152 I want to fly mainly. I leave handling the avionics in the 182 to the panel itself. I *think* there was a situation where the avionics was disabled, but that wasn't reflected on the panel itself. With the avionics disabled, there were no updates from FS, and no events I sent were picked up. Hence, there were no updates. Now I'm no longer managing the avionics from my own panel; and it looks like my instrument is now working correctly.

I will clone the 182 panel and remove the instruments the 152 doesn't have. I hope AM4 sees light soon, and there is a better 152 panel that I can use. I can write software, but cannot create graphics. A man needs to know his weaknesses

As said, for transparency, I'm posting my code again

I haven't followed this closely. Was the problem solved or is there still something we should look at?

[bartroozendaal]

It happened a couple of times again. I am suspecting there is some error in am or in the fs2020 Bridge. But, I can reset the application when it happens and start over.

Let's close the issue for now, but I might be back with more info on it.

If you have beta 33 available still somewhere, I can double check if it is indeed a new issue introduced with 35, or an old issue.

[Ralph]

No, we never store old versions. If it is something you can easily reproduce, then we can have an online debug session.

[bartroozendaal]

Yes, it happens quite regularly. Please let me know what time would best suit you. I do have a day job, but with the working from home situation, it should be possible to free up a bit of time during working hours....

No rush for me; I know what to do to get the instrument working. Sometimes I need a couple of tries, but eventually I can get it working again.

[Ralph]

Today is an option for us. Do you have time?

[bartroozendaal]

Yes. After 10:30 if that's ok with you. Ping me at bart@fysiofriends.com please. I can use Microsoft Teams (or anything else if you like that better)

[bartroozendaal]

Na 14:00

FYI and maybe future reference: the software (both mine as AirManager itself) worked fine. The problem I found was in a faulty soldering of the battery master switch. That gave intermittent errors in reading the status of that switch. Simply resoldering the ground solved this particular problem.

As you were ....

Credit where credit is due. !

Thanks ever so much for actually responding with the solution. It is, unfortunately rare that people do.
It is of no consequence that the issue is AM, Hardware, User, connections, setups whatever./ the main thing is that after a series of questions and answers to aid fault finding that you come back with an actual result that may well help many many others.
Thank you for you contribution and long may it continue, Your input is valued and indeed necessary to these forums.
Oh, how I hope some people learn from this. Again, a credit to you. THIS is how people learn.
Joe.
