ESP32 DEV MODULE - Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled

HI guys!

I'm working on a project were my ESP32 connects to the internet via WifI and send some BLE beacons readings to a MQTT server. The library wich i'm using to control the BLE connection is "NimBLE.h". This is relatively a huge project, consuming 58% of ESP32's storage. The problem i get n Serial Monitor is the following:

I read in some forums that this crash occurs when the program tries to access an invalid memory address location. In fact NimBLE works with some NULL pointers to manage the connections and somewhat this is the reason why ESP is crashing.... But i'm really stuck here....The code i'm working on is for professional purposes, so i'm not able to share with you guys.... I"d be really thankfull if you could help me :slight_smile:

So how can you expect an answer?

Then your two best options are:

  1. Create a small version of the program (one you can post) that demonstrates the problem. Then post it here.

  2. Pay somebody to fix your code for you .... after they sign an NDA. Paying (or getting paid) for work is what "professional" means.

Your Honor.. You for whom we are not worthy.. You get this and figure it out:

EDIT: Oh, and thank your precious highness for letting my unworthiness help..

The only clue you'll get with the posted code is that the above, most likely, means that an array is out of bounds.

Put the backtrace info into the ESPExceptionDecoder.

Good luck.
