I created an example which stops and restarts BLE.
testBLEESP32S3_240617_1_crashing_on_esp32s3.ino.zip

The example works on a "SEED XIAO BLE - nRF52840" board but crashes on a "XIAO_ESP32S3" board.
Hence the problem should be somewhere in the ArduinoBLE library or in the esp-idf framework.

Where ...

I'm using the XIAO_ESP32S3 board with ArduinoIDE with installed ArduinoBLE. It currently uses ESP-IDF v5.1.
I created a test sketch for BLE which crashes after disconnecting from the XIAO board which calls "BLE.end()". I attached the sketch and log in ESP_S32S3_BLE_crashing.zip
After checking the ...
