my project needs me to use one transmitter and have multiple receivers in the same channel basically all the receivers are identical and dont do much as well other than just turning an led on can i do this using zigbee modules if i can how i’m a complete noob to zigbee any help will me greatly appreciated
Zigbee is a Protocol. I think you mean XBee. Yes, the basic 802.15.4 XBee modules by default are in a peer to peer state. That means any node can and will talk to ALL other nodes that are in range.
For a Zigbee Mesh network, the Coordinator (CE1) by default sends out Broadcast packets to all nodes within the network and all routers or end devices, send their data to the coordinator (DL and DH 0) which is effectively a Point to multi-point network.
You can do the same on the 802.15.4 modules simply be setting the MY on the Coordinator to a value. Then set the coordinators DL and DH to the broadcast address of 0xFFFF. Then on the remotes, set them on a unique MY value and set the DL/DH to the MY value of the base.
thank you for the answer but how many nodes can be connected to a coordinator and what is the range of a xbee module in general im sorry if this is obvious im a complete noob
it is as follows:
Indoor / urban range Up to 200 ft (60 m) Up to 300 ft. (90 m)
Outdoor RF line-of-sight range Up to 4000 ft (1200 m) Up to 2 miles (3200 m)
There is no Max number of nodes specified. It supports as many as there are 16 bit addresses which is 65,550. So your real limit is total supported overall throughput.
