 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:
+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 later modify these radio parameters in the ''setup'' function by choosing one the following data rates:
+^  Data Rate   ^  Spreading Factor      ^  Bandwidth  ^
+|  DR0         |	SF12            |  125kHz   |
+|  DR1         |	SF11            |  125kHz   |
+|  DR2         |	SF10            |  125kHz   |
+|  DR3         |	SF9             |  125kHz   |
+|  DR4         |	SF8             |  125kHz   |
+|  DR5         |	SF7             |  125kHz   |
+|  DR6         |	SF7             |  250kHz   |
+In order to reduce collisions, configure the central frequency of your LoRa modules as below:
