Re: ESP-32 as BLE client: connection always closes after 40 seconds
but why is the void loop empty in your code? You don't need any code in the loop function if you are working with callbacks / event based API The callback handler is assigned in the line: client->setClientCallbacks(new MyClientCallback()); This takes care of handling incoming data in an event based...
