Only the GPIO pins used by this project are used.

Description

I am using the WLED project here: https://github.com/Aircoookie/WLED
I am trying to add BLE support to this project.
For that, I am using partitions based on the huge_app.csv file
Currently, I am facing an exception at run time when using BLE as well as WiFi in this.
Basically when I am initializing BLE first then the exception occurs when connecting to the WiFi network.
Similarly when I am connecting to WiFi network then an exception occurs at the BLE initializing.
I am attaching the trace for both in this ticket.

I have also uploaded the code from the usermod.cpp file where I am initializing BLE server, its basically the code taken from BLE example given in the ESP32.

Sketch

#include "wled.h"
/*
 * This v1 usermod file allows you to add own functionality to WLED more easily
 * See: https://github.com/Aircoookie/WLED/wiki/Add-own-functionality
 * EEPROM bytes 2750+ are reserved for your custom use case. (if you extend #define EEPSIZE in const.h)
 * If you just need 8 bytes, use 2551-2559 (you do not need to increase EEPSIZE)
 *
 * Consider the v2 usermod API if you need a more advanced feature set!

Not directly solving your issue, for Tasmota we use h2zero/NimBLE since the beginning of using BLE because it has a lower footprint for RAM and flash usage. It does work fine with latest core.
Maybe you give it a try. Afaik WLED uses Tasmota Platformio Arduino Esp32 core build. You should use latest Tasmota version build 2.0.3-rc1 for your work.

@Jason2866 I tried this library and the results are a bit better.
So it works correctly with the AccessPoint configuration of ESP32 but the issue occurs when the following configuration is used:
BLE init -> WiFi network connect -> AsyncWebServer creation.
Basically when WiFi is connected it remains ok but as soon as the webServer is initialized then the following exception occurs:

You have to search the bug. This combination does work without issues for Tasmota.
If you are using AsyncWebserver or LittleFS you are hitted by this bug #6502 #6507
To solve apply not merge reverting PR #6516
You can use my fork without the bug with platformio

platform = https://github.com/tasmota/platform-espressif32/releases/download/v2.0.3rc1/platform-espressif32-2.0.3.zip

[VojtechBartoska]

Can you please retest this with 2.0.3 Version? Thanks!

[VojtechBartoska]

Closing as expired, if needed please reopen the issue.

[jacobk]

@umerm64 Did you ever resolve this issue? (running into the same problem)

[Jason2866]

AsyncWebserver is outdated and not maintained. When used a lot of weird issues can happen.

[jacobk]

AsyncWebserver is outdated and not maintained. When used a lot of weird issues can happen.

I see @Jason2866 . I was encountering this using the latest version of WLED. Are you saying that the error is caused by AsyncWebserver (I guess WLED is still using an old version https://github.com/Aircoookie/ESPAsyncWebServer)

[Jason2866]

Not saying definitely ESPAsyncWebserver, observed weird issues when used in complex programs. Adding BLE to an already complex piece of code makes the situation worse.
Race conditions, hidden bugs and what else...

What i am saying trying to add another function to an currently working piece of code does not mean the error is always to search in the new added code part.

To track down the issue it has to be analysed where the issues happens and what's causing it. Everything else than easy in a complex project. No easy and fast answers possible.

[umerm64]

@jacobk I used h2zero/NimBLE for adding support of BLE in my code since with BLE lib provided by sdk was crashing.
After that, the issue did not occur.
But I didn't exactly find the solution.
But I would advise you to not use BLE and WiFi simultaneously.
