ESP32 Guru Meditation Error: Core 0 panic'ed (LoadProhibited). when using BLE

I am developing on ESP32 WROOWER using Arduino IDE.

When I use BLE in my sketch it bricks down, I dont know why. My sketch is big, 1416000 bytes and in Tool>Partition Scheme I selected "HUGE APP 3MB....".

Here is the backtrace:

    Guru Meditation Error: Core  0 panic'ed (LoadProhibited). Exception was unhandled.

And when I use decoder here is what it shows to me:

When I test BLE using Examples it works fine, but when I combine it with my sketch it fails...

If you know how to fix this please help me!

I received this error when I put noInterrupts() at the start of a function and left an exit that was not covered by interrupts(). When that exit was taken ......blam!!

Check the following:

  • Do you use String Class and do a lot off String constructions with String c = "a" + "b"
  • are you creating char arrays on the fly e.g. char d[] = "efg";
  • are you using delay() - get rid of it its blocking

If there is one Yes than you've found the reason, if its 3x No we need your code (github, pastebin) to do further analysis
