Hi Oleg,

I want to send data from end node to coordinator in API mode. The end node is connected to PIC18f452, I’m trying to send simple data ASCII 1 (API frame = 7E 000F 10 01 0000 0000 0000 0000 FFFE 00 00 31 C0) to coordinator, but the coordinator can not receive the data (the coordinator is connected to computer using X-CTU). Then i’m trying to use your code from this page (with some modification so it can fit my circuit), but it still can not send the data. I think there is no problem with the XBee firmware, cause i’ve tried to connect both device by using two computers, the data can be sent. Is there any additional requirement that i’ve missed in order to connect XBee with MCU ?

Thx

Hi, i’have developped an application for pic18f2620 with xbee series 2.
my application works fine when I use the method of reading parameters COMMAND MODE (I write “+ + +” , “ATNI”, “ATDH”, “ATDL” …. etc) and I can read perfectly by micorcontroler interrupts the Xbee module parameters. When I start to use frames Xbee API in the microcontroller is blocked in this line “while (DataRdyUSART ())”.. The Xbee module not respond to API frame..
For example if i send the following array CArray char [] = (0×7e, 0×00, 0×04, 0×08, 0×01, 0×6e, 0×69, 0×1f); ” i want to read the NODE IDENITFIER PARAMETER device from the Xbee Device but not respond … DataRdyUSART() dont receives nothing.
Whi?

There are several different firmware images for Xbee – coordinator, end device, etc. By design, two end devices won’t talk to each other, and two coordinators won’t talk to each other either. They come from the factory flashed as end devices, you need to reflash one of your Xbees to coordinator.

This is true for Xbees I’m talking about here, i.e., ver.2.[0,5] and API mode. There are many others, which are different.

I don’t upgrade firmware of xbee. I don’t know that why ??? Please,described for me
Thank you.

Were you able to make your two Xbees talk in serial emulation mode? Also, are you using proper firmware, i.e., coordinator on one of Xbees, router/end device on the other?

I’m using a PIC24HJ64GP502, I’ve configured two XBees using X-CTU to be in API mode. I’ve used libraries that have written by another person plus some of my own code for PIC24 in order to get it to write to UART_TX. I’ve connected one XBee to the PIC and the other to the comp running X-CTU terminal. The code I have creates a packet (as far as I know) and it is sending something to the XBee, but it’s not transmitting anything at all and the second XBee isn’t receiving anything, for obvious reasons. I’ve tried everything I know of, which really isn’t much, I’ve no idea what else to try.

I just finished my first project connecting avr32 with XBee

hope it can help someone.

The website below explains how to load API firmware onto your xbee. It’s not mention in the XBee product manual.

To understand better of API modes, refer to Chapter 9 of API operation from the Xbee product manual

My system is very simple, I have three Zigbee modules , all of them will transmit data to one Zigbee center, it looks like multi-point to point.How can i configure xbee.I want to use API mode in X-CTU?
Please show me the way to load API firmware to my modules.
Thanks for your help!
