I want to send some data from Coordinator to Router, then Router sends the same data to End Device. The End Device after doing some calculations, sends the Data to Router and Router sends the same data to Coordinator. So basically Router is just a range extender working as a bridge between Coordinator and End Device.
i have tried changing my modules to Coordinator, Router and End Device. The problem is, there are options of Coordinator and End Device in XCTU Software but there is no option of setting a module as Router (Relay). What arrangements do i need?
Should i Set one as Coordinator and other 2 as End Devices? Will it suffice the purpose?
“repeaters” can be done with the complex and elaborate mesh network protocols for XBee. Series 1 XBee can use Digi’s mesh protocol; series 2 XBee will use Ember’s ZigBee.
Simpler is for you to code a microprocessor attached to the XBee’s serial port to receive then retransmit packets. A simple hard-coded repeater, hard-coded as to upstream and downstream radio addresses.
I prefer to use peer to peer mode for such, no PAN coordinator, no association. Kind of like 802.11’s ad hoc mode, where nodes know a priori or discover via broadcasts their neighbor-nodes’ MAC addresses, for use in future transmissions.
PS: Not knowing if you have series 1 or 2 is like not knowing if you are eating an apple or an orange! There’s a FAQ here on that, and on Digi’s website. Part numbers also tell. Sorry, I don’t recall the coding from memory.
As for the repeaters, i ll try and do some experiments using DigiMesh first and if that doesnt suit, i ll try and go with repeaters as i have never heard of a Zigbee Repeater.
Suggestions are always Welcome, please do post if anybody has some other advices.
my earlier suggestion on repeaters - was not ZigBee or DigiMesh.
It’s where you utilize Series 1 in peer mode with no coordinator.
But no need for a repeater if you have adequate range without or with better antennas.
Controlling a relay would be simply using the Digi XBee virtual wire firmware, built-in, to control a remote DIO pin, wired to a proper relay driver, be that a mechanical relay or a solid state relay.
