Audio App crashes Portapack

[helmarw]

when switching from Audio app to e.g. TPMS and then back to Audio, Portapack crashes
see short video I recorded, happens also from other apps but only when going back to Audio

i m using the version just downloaded and compiled 2-3 hours ago.
the version I downloaded and compiled about three weeks ago (04-08 I think) did not have this issue as far as I know

Can you test both versions and be sure that the older one works? If you tell me the timestamp of the one that works vs the one that does not I can check the differences.

BTW I compiled the "latest" -> https://github.com/eried/portapack-havoc/releases

[helmarw]

k, will let you know, luckily i saved the "old" one, alt least the binary.
i will load it up and see if i can reproduce it there

[helmarw]

my mistake, havnt tested the older version very much (downloaded and compiled 8th April 2020). it has the same error.
it only happens when Audio is in WFM-mode, switching to TPMS and than back to Audio. that crashes the whole thing
second when i put audio in SPEC-mode and then change to TPMS i get a red screen (M4 GURU Meditation unhandled)... two short videos about that behaviour
crashes.zip

other modes AM and NFM are not influenced either way. I didnt test any other apps, too many possible combination, it just happend that i was using exactly those two configurations for testing my TPMS sensors

Strange I do not get a lock if I repeat exactly what you do in those videos, it might be a faulty portapack?

PS: btw! I noticed what a beautiful case, the mirrored engraved text worked flawlessly! 🤣🤣🤣

[helmarw]

i dont know what the Problem can be, that just how it is with my portapack

thnx, the housing is great, i printed it on a Formlabs Form2, work very well :)

I can replicate this as well. If i go into the audio app, set it to WFM, exit and then go into ACARS or TPMS i get a had lock with a red screen reading "M4 Guru Medidtation Unhandled". I can also lock up the audio receiver, by going into WFM mode, exiting audio receiver, and then reopening it. The main screen then partially loads the and then hard locks. Seems to be something caused by WFM mode in the audio app. If i can provide anymore information, please let me know.

I do not get the exact same type of lock up, but if I do audio, ACARS/TPMS and then back to audio, the audio app locks the portapack (only the upper part refreshes). Maybe some missing initialization stuff, I will play around it to see if I can find something

[eried]

Only with the audio app? I could check the initialization of that one but it would be helpful if you both @fcanaan @helmarw test all 👷‍♂️ the possible entering/exiting situations that work weird to pin point what is going on.

[fcanaan]

Yes, i've only noticed it with the audio app, specifically in WFM mode. I can help you test whatever scenarios you need.

Find the same problem in another app/in-out combination. Im no expert on the code, but with a few examples, it will be evident to fix 😂 I hope lol

[fcanaan]

Strangely, the only error I can now replicate over and over is open audio, switch to wfm mode, exit audio, open audio again, crash. Top 1/3 of receiver menu shows the rest of the screen is black. Hard lock, have to reset. IF I open another Listener app, close it,and then open audio again, it does not crash. Will keep testing.

I’ve found a repeatable M4 Guru error.
Turn unit on
Select Receivers
select pocsag wait 5 seconds then exit
Select audio. change to spec mode. wait 5 seconds then exit
select radiosonde
M4 Guru Meditation Unhandled hard lock up.

[eried]

I can confirm tht M4 guru error, awesome! I will buzz around the code to see if I can find the source of the problem

[eried]

I think I found a way to make it stop hanging :) it needs a call to on_modulation_changed( in the constructor

@fcanaan have you found more bugs? I want to be sure I am not breaking something else before posting the fix
