NodeMCU MQTT Client with Arduino IDE - NodeMCU

To properly assure qos 1 delivery, the client needs to store the message until it receives the acknowledgement from the server. This allows it to resend the message if it does not get that ack. By ‘store’, that could simply mean in memory, or in some non-volatile storage. If it is in memory only, then it will be lost if the Arduino resets.
