Xbee Pro explorer and Xbee Pro Shielded Arduino Pro

Wireless & IoT
1

I have been trying to communicate between 2 Xbee pro Series 1 modules for 3 days. I have tried numerous tutorials with no success. I am beginning to think the problem is with the hardware.

I bought all of the following from here:

2 x Xbee Pro Series one wire antennae

1 x Xbee Explorer Regulator

1 x Xbee Shield

1 x Arduino Pro 328 5V

I have only changed the following parameters from their factory settings wiith XCTU:

Module 1:

ATID=6666

ATMY=1

ATDL=2

Module 2:

ATID=6666

ATMY=2

ATDL=1

I connect the shield to the Arduino pro to its own independent power supply of 9V. The Power LED of the Shield lights up, but the weird thing is that I am able to upload code onto the Arduino with the shield’s switch in UART and DLINE positions. I connect the the explorer Xbee module to the computer via a FTDI cable.

I switch the Shield to UART mode but the DIN and DOUT LEDs on the shield and explorer do not blink when I use a simple code to send serial data between them.

I try to just send Serial.print(“Hello World”) through the Xbees but it doesnt work. When I connect the Arduino pro’s serial directly to the FTDI cable, it works.

What I am trying to figure out is the following:

  1. The parts I ordered are not compatible

  2. Something is wrong with the parts (Xbee or the Shield)

Any help would be greatly appreciated as I have hit a brick wall.

I’ll assume the XBee Pro are series 1, not series 2.

You do have the PAN ID and channel matching, right?

If you revert the modules’ configs to that as shipped, usually they will work out of the box in serial port extension mode.
