Hello All,

Want to have broadcast message, for one collector and 10 nodes.

I changed

dataReq.txOptions.indirect = false;

dataReq.txOptions.ack = false;

dataReq.dstAddr.addr.shortAddr = 0xFFFF;

in my collector application.

I checked that from collector i am sending messages to all nodes succesfully.

But on Node side i am not receiving any message.

node side i am using sdk 2_40_00_20 version

Does i need to change any thing on node side to properly receive these packets.

Thanks,

Pratik

Is you sensor under sleeping mode so it cannot receive message?

Yes, agreed it is in sleep mode.
But when a data comes, at that time this funcation dataInd(); should be called right?

Thanks,
Pratik

If sensor node is in sleep mode, I don't think it can receive data.

Well, whole sensor application is built and configured in low power mode.
Which means that after sending data, application goes to sleep.
Than how it is responding to config cmd, tracking cmd, which is coming in between.
Which states that application wakes up on RX.
Is my understanding correct.

Thanks,
Pratik

Do you run the example in beacon mode or none beacon mode?

I m running in Non-beacon mode.

In non-beacon mode, sleeping sensor needs to wake up to polling for data. It won’t be able to receive broadcast data in sleeping status.

Than what is the solution for this ?
Anyhow i want to receive that data.

Try to set “#define CONFIG_RX_ON_IDLE true“

Thanks Yikai, it worked..!!!

I have tried this and i am receiving correct packet.

But this makes my device as non-sleepy.

and i am not able to set the reporting and polling from collector in this case.

Being a non-sleepy device won't solve the issue.

can you help me with another approach.

Thanks,

Pratik

If you want to make sensor to receive broadcast messages any time, there’s no alternative other than set CONFIG_RX_ON_IDLE as true.
