Test board

Here an example of running communication on my test board with 4 devices:

A nodered instance is used to receive (via MQTT) the communication stats.

Sometimes you can see the message **M(number1)/(number2)/(number3)/(number3). These numbers mean:

number1: number of messages exchanged number2: number of token exchanged number3: number of CRC errors number4: number of loss messages lenght mismatch (occur on sync loss, when the receiver get an end message byte in an unexpected position)
