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 writing
(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
not to exceed the "LoRa configuration parameters" range) → click "Write" in "LoRa Configuration" → see the "Log"
column pops up a prompt indicating that the writing is successful → click "Save" → see the "Log" column pops up to
save successfully, then complete the configuration → click "Reboot the device.
(2) Next, you can verify whether the parameters are correct: repeat the "LoRa parameter reading steps" operation steps.
