It took me some time to understand what this exactly does. Using a state enum would make the code more readable and prevent multiple calls to connect that may lead to memory leak.

(scan_period_t)0
);
if (ret == BLE_ERROR_NONE) {
_connection_parameters = new ConnectionParameters(connectionParams);

Can you release it in reset

Thanks, I added an enum and used the extra 3rd state to avoid having an internal connect since the connect is called synchronously from the scan result so I can use that state to know it's an internal call.
