Xbee transmitting problems

Wireless & IoT
1

Hello there, i have been having trouble with my xbees for comunication and i was wondering if i can get some help here. I have two known good programs, one, is for receive, the other one is for transmitting. My set up: Xbee starter kit from trossen robotic which includes ths sparkfun xbee explorere and the xbee regulated board, i have an arduino MEGA connected to the xbee regulated board with 5V, gnd,dain and Daout; that is going to be the receiving side. And i have an arduino nano V3.0 connected to the xbee explorer by its 4 wires (same as the other one).

When i load the transmitting program into the Arduino mega, the xbee transmit light blinks and it seems to be sending just fine, but i dont see anything on the reciving side. But when i load the same transmitting program into the Arduino nano, the transmit led does not do anything and i dont see anything in the serial screen. The xbees are brand new!.

Some suspicious things:

  1. I cant load a program into the arduino nano if the xbee is powered up, i get an error message.

  2. The xbees are already paired as i followed the tutorial found in this website.

Any help? i only have a few days to get this working

Is there any chance that arduino nano V3.0 does not support wireless transmission?

PS: the arduino nano seems to be fine as ivahe tried loading other programs into it and they work just fine.

Pk, I assume you have Series 1 XBees running firmware for the straight 802.15.4 protocol. If not state so in your next post. Also, what is the Firmware version number in your XBees. This nails down exactly which XBees you have and which documents is the correct one.

Do the XBees work correctly with X-CTU?

I didn’t see a link to the web site you used for setting them up!

Did you set the DL and DH XBee parameters to the SL & SH parameter of the other XBee?

By saying you have code that works I’ll assume that you have used this code with the arduino mega and arduino nano V3.0 without the XBees and communications worked.

Do you have the TX data from the arduino going to the XBee’s DIN and the XBee’s Dout to the RX data one the arduino?

Do the Baud rates match between the XBee and arduino?

Have you downloaded the proper XBee Document from Digi International?

Is there any chance that arduino nano V3.0 does not support wireless transmission?

The nano doesn't need to know anything about wireless. This is just serial communication, Async in to one XBee and the same out of the other XBee.

This is a rather common issue and there are a number of threads. Do look through the Wireless/RF forum for more questions and answers.
