XBee Pro to PIC18f87j11

Hi Guys,

I am having a hard time interfacing the XBee-Pro module to my PIC. I have the right connections but I dont see anything on the X-CTU terminal. I am using a usb explorer board from sparkfun to hook it up to the computer and the other XBee pro is connected to the PIC18 using RX,TX,GND and VCC pins. I am using PICdem development board from digi for the microcontroller. I checked the TX from PIC, it is giving me 1.29V but its not showing anything when its connected to RX of XBee in the terminal. I already have the baud rate setup for the microcontroller. Please help me, I have been working on this for a long time but can’t get it to work. Any help will be appreciated. thanks

I checked the TX from PIC, it is giving me 1.29V

Is this the voltage level as checked with an O'scope? If so then neither a valid high or low logic level and may be that the PIC's TX pin is not properly set-up.

Have you gotten the PIC to communicate with the PC, using the proper level translator (MAX232)?

If not start without the XBees and get the PIC’s UART code working. Read Microchip App Note AN774 with sample code for using the UART.

Also, search this forum for many, many threads on getting XBees working.
