Example with arduino.png

There are two examples in this code, one is sending data and another is receiving data. File:Get the code here.
Set different bands for different countries, here is very easy to change: nrf905.write_config(US); Just enter your country or area as a parameter in this function. In fact, you have choices:

Country Band
US 908.42Mhz
EU 868.42Mhz
Africa 868.42Mhz
China 868.42Mhz
HK 919.82Mhz
Japan 853.42Mhz
Australia 921.42Mhz
New_zealand 921.42Mhz
Brasil 921.42Mhz
Russia 896Mhz

upload the two examples into two arduino boards, one for sending and other one for receiving:

On the receiving end, you should be able to see:
Hi, Arduino 0,
Hi, Arduino 1,
Hi, Arduino 2,
