[DTTerastar]

A user thinks the issue started in 1.3.5:

ESPresense/ESPresense#241 (comment)

[h2zero]

Thanks for reporting this. I'll have a look into it.

[DTTerastar]

I've seen it even as far back as 1.3.4. Testing 1.3.3 right now.

[h2zero]

I'm still unable to reproduce this. I'm not sure what the error could be as that code has not been changed in a very long time.

[h2zero]

I've opened PR #354, it may or may not help with this. If you want to give it a test and let me know, I'd appreciate it.

[DTTerastar]

Ok, got it to work, testing now.

***ERROR*** A stack overflow in task BLE Scan has been detected.

Thanks, looks like there are a few things to deal with. Looking at your repo I see:

build_flags =
	-D CONFIG_BT_NIMBLE_PINNED_TO_CORE=1

Any particular reason to set this to core 1? It would be better in my opinion to change the tasks that make calls into the BLE stack run on core 0 and leave this on core 0 so that the wifi and ble core tasks don't have as many sync issues.

me-no-dev/AsyncTCP@^1.1.1

This is a red flag, async and BLE do not work well together, known and ongoing issue. Not certain it could cause your issues but it is a factor to consider.

It appears that your "BLE scan" task is overflowing it's stack in these logs, bumping that up a bit should resolve a few of these.

[thorrak]

Are you stopping and restarting scanning? Are you running an active scan? If so, you may be running into the issue that I had, which resulted in a similar stack trace to the heap corruption one you quoted.
