How to diagnose crashes? - ticky - 2024-12-19
I've been enjoying using my Tangara since I got it the other day, thank you for all your hard work!
I've encountered a couple of crashes in my time using it, and I'm wondering what the best way is to tell what's gone wrong, and supply you with crash information to help improve the firmware over time?

Hi! Glad you're enjoying your device!!
If you have consistent repro steps, then sharing those is usually enough for us to dig in. Otherwise, you *can* get stacktraces off the device, but it currently requires you to be running a dev build + have `idf.py monitor` running and connected to the device at the time of the crash. If this is the case, you'll get a full stacktrace showing the point of the crash. These are very very helpful!!

Nothing particularly consistent, just having loaded my music onto my device (chiefly converted to opus format using beets as the majority of my library is in AAC or ALAC) I have pretty frequent crashes when playing back via Bluetooth. It's not consistent but it seems most correlated with loading the next track. I'll see if they still happen while listening via the headphone jack later.
