 +Download the {{ :sketch-1819.zip | basic sketches}} that implement a simple LoRa communication between the two modules. Open the sketches with Arduino IDE.
  
 Start by setting the central frequency of your LoRa modules according to the following table: Start by setting the central frequency of your LoRa modules according to the following table:
Line 83: Line 85:
 |       12       |      868.9      | |       12       |      868.9      |
  
-For this, open the ''RH_RF95.cpp'' file located in the ''RadioHead'' folder and change the frequency using the following command: 
- 
-<file cpp RH_RF95.cpp> 
-setFrequency(86X.Y); 
-</file> 
  
 The typical configuration for LoRa modules consists of 125 kHz sub-channels, a coding rate of 4/5, and a spreading factor equal to 7. You can modify the radio parameters by selecting one of the three available configurations: The typical configuration for LoRa modules consists of 125 kHz sub-channels, a coding rate of 4/5, and a spreading factor equal to 7. You can modify the radio parameters by selecting one of the three available configurations:
  
-  * Bw125Cr45Sf128 
-  * Bw125Cr48Sf4096 
-  * Bw31_25Cr48Sf512

-Radio configuration is applied in ''RH_RF95.cpp'' as in the following example: 
-<file cpp RH_RF95.cpp> 
-setModemConfig(Bw125Cr45Sf128);
