4.2 LORA parameter
4.2.1 Basic wireless parameters
Channel: The equipment that needs to communicate should work on the same channel, and the current
operating band can be calculated based on the channel value;
Operating frequency = minimum frequency band + channel value * channel interval
Module address: Transparent transmission should ensure that the devices that need to communicate have the
same address, in fixed mode to distinguish between different devices on the same channel, relay mode is used to
configure the relay address of the data, the configuration range 0 to 65535;
Network ID: Transparent transmission should ensure that the network IDs of the devices that need to
communicate are the same, and in relay mode is used to distinguish the destination of the data, with a configuration
range of 0 to 255;
Airspeed: ensure that the devices that need to communicate have the same airspeed;
Sub-packet length: to ensure that the devices that need to communicate have the same sub-packet;
4.2.2 Broadcast and monitoring
Set the DTU wireless address to 0xFFFF: it can listen to the data transmission of all modules on the same
channel; the sent data can be received by modules with any address on the same channel, thus playing the role of
