 ===== -. Modifying the Radio Parameters =====
-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. This configuration ensures higher data rates but is more vulnerable in case of harsh radio conditions. If you want to ensure more robustness to noise on the radio channel or extend the coverage, you may change the module configuration to a stronger coding rate of 4/8 and a spreading factor of 12. This obviously comes at the expense of lower data rates ! The procedure is explained in the following.
