Xbee Series 2 using UART.

Wireless & IoT
1

Hi,

I am doing a project using Xbee Series 2 to communicate with a microcontroller(board with LCD display) sending fixed number thru UART as a base project before i do any more upgrade on my microcontroller.

Everything was going as planned individually. I manage to display the fixed integer i input on my LCD display, i also did try to communicate my xbee series 2 ZNET 2.5 ROUTER/END DEVICE AT with the ZNET 2.5 COORDINATOR AT.

When i connect them together thru UART with my board UART Output Pin to xbee coordinator UART input pin. i am unable to get any signal out of it. UART ports on my microcontroller board is enabled.

Is there any more settings i need to do on my XBEE series 2, or any solution on what i should do? Please advice.

Thanks in advance

Best Regards

Have you got the baud rates and parity bits etc… set up the same on the uC and Xbee?

Baudrate are both the same at 112500.

Test the Xbee using the dev board or Explorer and a PC, and test your PIC UART by tying RX and TX together. They they are both functioning as expecting, replace the RX/TX link on the pic with the TX/RX of the Xbee. Remember that DOUT on the Xbee needs to go to DIN (RX) on the PIC, not TX), so its RX to TX and TX to RX.
