I'm not too sure what the error is yet, the logs suggest an error in a value passed during pairing. What kind of pairing does the other device expect? If...

You should also remove this: ``` NimBLESecurity *SECURITY_MANDATORY = new BLESecurity(); /** * @brief Set requested authentication mode * @param [in] auth_req A bitmask containing one or more of: *...

I would encourage not to use the security class as it has been deprecated. The equivalent call is simply: ``` NimBLEDevice::setSecurityAuth(true, false, false); // enable bonding, no MITM, no SC...

Looks good to me
