+Download the {{ :sketch-1819.zip | basic sketches}} that implement a simple LoRa communication between the two modules: a client module and a server module. Open the sketches with Arduino IDE. Make sure to choose the correct ''Board'' and ''Port'' in the ''Tools'' menu.
 Start by setting the central frequency of your LoRa modules according to the following table:

 |       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:
-  * Bw125Cr45Sf128

-  * Bw125Cr48Sf4096
-  * Bw31_25Cr48Sf512
-Radio configuration is applied in ''RH_RF95.cpp'' as in the following example:
-<file cpp RH_RF95.cpp>
-setModemConfig(Bw125Cr45Sf128);
