Fields in up messages from MQTT

[kirill.chugunov01@mail.ru]

Hello,

I would like to a bit description for up messages from MQTT.
I’ve read the article MQTT Messages. There have descriptions of messages from MQTT. But I didn’t found few fields. Can I have desriptions for these? I am about fields:

• nonce (I found in join_request & packet_recv topics)
• ipol (I found in the packet_sent topic)
• ncrc (I found in the packet_sent topic)
• powe (I found in the packet_sent topic)
• twnd (I found in the packet_sent topic)

Also, I would like to get more deeply description for these fields:

• rfch (I don’t understand what this)
• fcnt & seqn (Why Multitech send packet sequence number of different bit size? )
• cls (What does show this control byte?)

Thanks and Regards
Kirill
