5.1.2 LoRa parameter description

(1) LoRa wireless address: It can be understood as the address number of the module, which can be used to identify
identities between devices. Therefore, two devices with the same wireless address can identify and communicate with
wireless data. Unlike ModBus addresses, the two exist independently.
(2) LoRa wireless channel: The actual frequency of radio frequency transmission is related to the channel, and devices
with the same two channels can perform wireless data communication.
Formula: LoRa wireless transmission actual frequency=410.125(850.125)Mhz+channel*1Mhz
(3) LoRa wireless air rate (airspeed):
1. The faster the airspeed → the shorter the time from sending the data to the receiving end receiving the response data
→ the shorter the wireless transmission distance.
2. The slower the airspeed → the longer the time from sending the data to the receiving end receiving the response data
→ the longer the wireless transmission distance.
3. For the relationship between the airspeed and the refresh interval, see the chapter "Acquisition Frequency and Range
Configuration".
(4) To sum up, only devices with the same LoRa wireless address, channel, and airspeed can perform data
communication.

5.1.3 LoRa parameter configuration write

(1) Steps (see Figure 4-10 below): Select the correct COM port number and correct (default) parameters → click "Open
Serial Port" (if you have changed the parameters and forget them, you can restore the factory settings) → "Search/Read
Device" → Read "Device Properties" successfully → Click "Read" in "LoRa Configuration" → "5" shows the current
LoRa configuration parameter information → Change the parameters to the information required by the user (be careful
