Xbee Series 2B Broadcast - Not Working

Wireless & IoT
1

Hi All,

I am not able to get the co-ordinator to broadcast the data to router

My setup works fine in unicast but not in broadcast when coordinator ATDL is set as ‘FFFF’

My Setup

2 x Xbee XBP24-BZ7WIT-004 revE

1 configured as coordinator and hooked up to PC via USB Explorer connected via CoolTerm.

1 configured as router and hooked up to arduino to blink an led when char ‘a’ is sent from coordinator.

My Broadcast settings

Coordinator Commands done to setup

ATID 2001

ATDH 0013A200

ATDL FFFF

I first clear all existing settings with ATRE and then specify the ATID, ATDH, ATDL

I first clear all existing settings with ATRE and then specify the ATID, ATDH, ATDL

I do specify the Coordinators ATDL for the Router

With this setup i do receive any communication from Router to coordinator.

I am not able to broadcast from Coordinator to Router.

Is it compulsory that for Coordinator to do a broadcast it must have more than 2 routers.

Where am i going wrong ???

Please help me figure this out i am loosing my head.

Guys sorry for posting my query i figured it out.

The answer was [here

In order to send a Broadcast message set the DH=0x0 and the DL=0xFFFF. With these settings all XBee modules on a given PAN will get the message.

I just had to change my ATDH from 0013A200 to 0 thats it.
