Two versions of an echo test for new devices are offered using paho-mqtt. The first (paho_echo_client) is a simple echo script which after a message sends it back with "echo-" at the beginning.
The extended version sends all messages back in the same topic and also sends all of them to a central topic("server_topic" by default). As another functionality it counts the words of the messages sent and sends the information to a specific topic("message_length" by default).
