	The RadioHead Library simplifies communication between the Arduino Board and the Lora Shield.We can find it ~~here:~~ http://www.airspayce.com/mikem/arduino/RadioHead/ To use it in your project you just have to copy it in your Arduino project folder (next to your main Arduino project file .ino).After putting the lIbrary in the right place, you have to also modify the frequency to the frequency you want to use, the position of this is setFrequency() in the file: arduino-xxx\libraries\RadioHead\RH_RF95.cpp; Then ,we can easily to use it to do some experimentation.
