Hello..I have to do a network xbee,where there is one coodinator and there are two end devices too.I need that all xbee’s modules will communicate,the coordinator will send the information and the other modules will recive the information.Now how can I make that network??? Please Help me!! thanks…

I haven’t been involved in Xbee projects lately so I start forgetting the details. Have you looked in the manual yet – there is plenty of information there?

Hi Oleg,

thanks for your tuto.

I try to develop a network with one coordinator and four end-devices.

in a first time, i send at command to switch adress destination, but this was very very too slow. ( about 2s)

So i decided to use API mode:

1- I send the At command ATAP 1 to enable API on coordinator module without change module firmware (10A1)

2- So when end-device send data to the coordinator ( with X-CTU, or a C function), coordinator can received a API sentence with the data.

3-But when coordinator send data in API sentence ( with mine or your function) to a end-device, none data are sending. I use a RS232 analyser to be sure.

4- When coordinator send AT command with API sentence, xbee module put the corresponding answer.

So my questions is :

A) Does it REALLY necesary to load Coordinator firmware on coordinator zigbee to send API sentence to end-device?

B) When i try to load API firmware ( ZIGBEE PRO COORDINATOR API (BETA) version 8114 for coordinator or ZIGBEE PRO ROUTERAPI (BETA)version 8314 for End-Device ), i always have a Big problem, when X-CTU want to send AT parameter whereas i check API enable: It stop with a failed message. X-CTU can’t recognised the module, and i can’t do anything!!Have you any suggestions?

C) If coordinator with API Enable can receive data from end-device with API Disable, Does End-Device with API Disable can receive data from coordinator module with API Enable ?

Best Regards

You will need to do bit bang serial. There is plenty of examples on the net how to do it.

Hi Oleg,

If my USART pin (RC6/RC7) already using for connect with the MCP2551 (can bus transmitter), how can i connect with xbee?

Thanks… I had some problem to connect the xbee with PIC. which pin of PIC should i use to connect with the Tx/Rx of Xbee to make the connection??

PIC talks to xbee via USART; the answer to your question is ‘yes’.

Hi Oleg,

i’m using PIC18F258 as canbus connect with sensor and sent data to pc though zigbee.

My question is did the PIC can direct connect with xbee without any radio chip??

Hi, i have picked a zigbee related project for my design class. I am trying to establish a connection between two zigbees (series2,usb enabled). One attached to the output of the smoke detector and one connected to the computer. I want to establish communication between the smoke detector and the computer through these zigbees.

Any idea!

Hi Oleg,
There is a coexistence between ZigBee and Bluetooth results in interference, i saw a bluetooth module to address the same. Can you explain more on this module. I await for your reply via my email ID manomactech@gmail.com
