conflict with wifi

[leoncoolmoon]

I think this library might conflict with wifi. I put the wifi stuff and BLE stuff in two separate functions. When I comment out any one of them the program running ok. But if not, the program will upload, but the esp32 will reset halfway through starting. In my program wifi starts before BLE. The wifi starts ok, then before any of the BLE mouse libraries been used the chip is crashed. I think it is because BLE and wifi share the same antenna. any chance you can modify the library, so before "begin()" were called, the library will not use any BLE hardware, please?

just put your sample code with the esp32-cam CameraWebServer code can recreate the error. code for CameraWebServer.ino: no change to any other code.

I encountered the same problem ，when i used the wifi and ble at same time.

The mouse library might just use too much ram for it to work properly together with the Wifi libraries. Reducing the memory footprint would require a refactoring of this library just like to how it has been done with the keyboard library. Maybe someone will do it some day.

Same issue here, it´s a pity this issue has not been solved but it´s understandable as it seems a big chunk of work, but I am glad I found this issue because I thought I was getting crazy as it didn´t make sense to me that wifi and BLE were interfering (obviously the memory issue make sense).

Have you tried the following?

I am trying to add that library to VS Code but it is not finding it (I think the reason might be that this fork doesn´t have any release). I will try to download it manually and add it to my project in VS Code, but do you think the memory issue is solved in this version?

[heisenberg2980]

@touchgadget IT WORKS!! Using the new repo was a bit of a challenge as it has dependencies on another repo (NimBLE-Arduino), but once I figured out how to add both repos to the project in VS Code it works, and the memory error when trying to use wifi and BLE at the same time doesn´t happen anymore. I even added OTA (which was causing other memory issues before) without any problem.

For anyone arriving here with the same issue, you can replace the original library (T-vK/ESP32-BLE-Mouse) with the new one proposed by @touchgadget in Visual Studio Code by adding these lines to the platformio.ini file:

lib_deps = 
    https://github.com/wakwak-koba/ESP32-NimBLE-Mouse.git  #master
    h2zero/NimBLE-Arduino@^1.4.0

Note: The repo wakwak-koba/ESP32-NimBLE-Mouse doesn´t have any releases so the only way I found to add it to VS Code is by adding the repo url (if anyone knows a better way please advice).

Thanks for sharing. This works for me!
