onAuthenticationComplete() never called about nimble-arduino HOT 2 CLOSED

Hello and welcome!

I'll save you some code here, you can replace this:

NimBLEDevice::setSecurityAuth(true, false, true);
NimBLESecurity *pSecurity = new NimBLESecurity();
pSecurity->setAuthenticationMode(BLE_SM_PAIR_AUTHREQ_BOND);
pSecurity->setCapability(ESP_IO_CAP_NONE);
pSecurity->setRespEncryptionKey(ESP_BLE_ENC_KEY_MASK | ESP_BLE_ID_KEY_MASK);

With just:

NimBLEDevice::setSecurityAuth(true, false, true);

Then the pairing/encryption should happen automatically when reading/writing to the devices characteristics, but if they do not enforce it that way then you should wait until connected and call pClient->secureConnection(); in your onConnect() callback method. Calling that before being connected results in the error code you see in the log.

Thank you for the super quick answer!
To set pClient->secureConnection(); in onConnect() was the solution!

Thank you!
