(3) The second communication parameter is configured in pairs: check the communication mode of the product model →
check the writing procedure of the second communication configuration according to the communication mode → refer
to the chapter "parameter reading, description and writing of the second communication mode".
Example: The second communication method is: LoRa wireless spread spectrum. In the second communication
configuration writing step, it is necessary to configure the LoRa channel, LoRa address, and LoRa airspeed of the sender
and the receiver to be the same. For details, see the "Second Communication Method: LoRa" chapter.
(4) Notes:
a. In a group, there must be at least one receiving end with a reply, otherwise the communication module of the sending
end will be restarted and the communication quality will be affected.
b. In a group, all the receivers have replies. If the number is too large, data conflicts will occur, which will also affect the
communication quality. It is recommended that the number of receivers with replies should not exceed 4.
To sum up: if less than or equal to one group, the number of receivers (with replies) is less than or equal to 4.
Correct combination example: 1 n receivers combined pairing: then write the configuration of 1 sender and 1
receiver as "one-to-many (with reply)" mode, and configure the other receivers Write as "one-to-many (no reply)" mode.
See Figure 4-22 below.
