How to perform wireless transmission with XBee

Before performing the wireless transmission with XBee, please make sure the wireless network built by two XBee modules is work properly.

1. Set the jumpers on ARPI600:

   Here, we should use two Raspberry Pi boards: Raspberry Pi-A and Raspberry Pi-B, of which Raspberry Pi-A is used for transmitting data and Raspberry Pi-B is used for receiving data.

   Connect Raspberry Pi-A to the serial port of XBee-A and Raspberry Pi-B toXBee-B, respectively. And then, set the jumpers on ARPI600, as the shows.

   • Connect XB_RX to P_TX
   • Connect XB_TX to P_RX

   Setting jumpers on ARPI600

   

2. Testing the serial port:

   Copy the file program/Xbee/getdata to the Raspberry Pi-B, and enter the folder getdata.

   Then, execute the code:sudo makesudo ./serialTest

   The relative data will be displayed as followed.

3. Run the code for transmitting data on Raspberry Pi-A. Then, copy program/Xbee/send into the Raspbian, and enter the folder send to execute the following code:sudo makesudo ./serialTest

   You will see the following message displayed in the PuTTY of Raspberry Pi-B.
