### Why does this happen? Who can explain it? 

Thank you very much.

Could you use this tool to debug stacktrace: https://github.com/nkolban/esp32-snippets/blob/master/cpp_utils/ArduinoBLE.md#decoding-an-exception-stack-trace

Thank you very much.

This looks strange. Line 410 is debug line: https://github.com/nkolban/ESP32_BLE_Arduino/blob/master/src/BLEAdvertisedDevice.cpp#L410

Could you try to change log level in arduino to WARN or ERROR? Also test your code how it work without touch procedure, sending some notifications and with touch but without sending nootifications.

PS Its small chance its problem with stack size, thats why error occured right here

dtboy1995 commented 6 years ago

in loop function, it works well

i change log level

please forgive me for not understanding.

Thank you very much.

No problem, all is good.

I think i know where is the problem, but you will have to make some workaround to make it working. Probably the issue is with pCharacteristic->notify();, this is blocking function (with semaphores) and probably touchAttachInterrupt has problem with it. Try something like that:

void gotTouch(){
   // if touched ...
   if (deviceConnected) {
       pCharacteristic->setValue(&value, 1);
       pCharacteristic->notify();
       value++;
  }
  isTouch = false;
}

bool isTouch = false;
void gotTouchSet(){
  isTouch = true;
}
touchAttachInterrupt(T0, gotTouchSet, 40);

void loop(){
if(isTouch){
  gotTouch();
}
...
}
dtboy1995 commented 6 years ago

I think you're right. It's a very good idea. :+1: Thank you very much.

PS In fact, my original idea was that touch interrupts and the main loop did not affect each other, so I wrote this code.
