Arduino examples of the BLE_Server and BLE_Client applications do not connect

Hi All, The examples of the applications BLE_Server and BLE_Client in Arduino, do not connect, even configuring the two applications with the same UUID, I verified that the client application can not determine the UUID of the Server, so it can not conenct, can someone help me?

Some logs or code would be helpful, especially onResult function.

Hi, same problem here.

Code of BLE server is a example from Arduino IDE:

  Serial.println("Starting BLE work!");

  BLEDevice::init("MyESP32");
  BLEServer *pServer = BLEDevice::createServer();

void loop() {

Code of the client is also frome Arduino IDE example - only the Service und Char UUID were changed and println for the haveServiceUUID function added:

I use two nodeMCU ESP32S boards. Thank you in advance!

Ok, i am suspecting that in both cases the issue is that arduino ble library is not ready for multi-connect usage. You are having problems because BLEClient and BLEServer are both are trying to register app with index 0:
https://github.com/nkolban/ESP32_BLE_Ar ... r.cpp#L307
https://github.com/nkolban/ESP32_BLE_Ar ... nt.cpp#L99

At beginning you can try to change one index.
