How to send commands to multi xbee at one time?

0 votes
Hi all,

I'm trying to set up a system where I take one xbee (series 1 or 2 it doesn't matter, I haven't decided yet) set as co-ordinator and three end devices.

The goal is to have the co-ordination connected to processing via use and laptop(although an iPad would be ideal) and then the three end devices connected to arduino connected to LEDs.

I'd like to control the LEDs from processing. But I am having a brutal time finding any information on doing this. I've seen lots of going from 3 sensors to 1 receiver and displaying the data. I need to go the other way.

I think API mode will work. Or even AT mode in broadcast mode. I have an idea for that. But Im worried about the quality of the signal. I could just say when xbee/arduino end device get the signal it runs a program.

I hope that explains it. Let me know if I can fill in more details.

Thank you!

Why don;t you just use the XBee 802.15.4 modules and their over the air command functions with the DIO lines. This way you can turn on and off an LED connected to a DIO line without the use of an external processor or micro controller.

That is done in this case by sending a Remote AT command to change the state of a DIO line from a Low to a high state.

Example API frame:
7E 00 10 17 01 00 13 A2 00 40 65 89 64 FF FE 02 44 31 05 27
