Many to one routing

Other Parts Discussed in Thread: CC2538

Hi,

I am trying to communicate between a coordinator and 20 routers.

How can I use the concept of many to one routing since all 20 routers will talk to coordinator only and coordinator sends same messages to all routers.

Thanks in Advance

do you want to re-broadcast the msg to other router？

Do you mean to send a message to all of those routers at the same time or you intend to use many-to-one routing?

both,

means from coordinator send a message to all of the router and messages from all router's will be unicasted to coordinator

1. You can define the following defines in compile options to enable many-to-one.
-DSRC_RTG_EXPIRY_TIME=255
-DCONCENTRATOR_ENABLE=TRUE
-DCONCENTRATOR_DISCOVERY_TIME=60
-DMAX_RTG_SRC_ENTRIES=100
2. You can assign your ZRs to the same group and use group cast to send message to all of those ZRs at the same time.

1. do i need to enable these settings in coordinator

2. When going through the zstack developer's guide i came up with an api

NLME_RouteDiscoveryRequest( uint16 DstAddress, byte options, uint8 radius )

do i need to call this api?

3. If yes at which intervals do i call this api.

Thanks for above answers,

As I know, he has his own CC2538 custom PCBs to do this test.

sir,
what is the differnce between custom PCBs and SMARTRF05EB with CC2530EMs

It means sibin design his own CC2538 module which would be used on his products later. It's for production purpose and CC253xDK is for evaluation.
