CC1310: How send information on beacon payload of Ti 15.4 Stack

Renato

Part Number: CC1310

Hello,

I've seen in some forum questions that i can use the beacon payload to broadcast information from the coordinator to all sensors, but i can not find any example or documentation of how i can do that.

Best regards.

As I know, beacon frame is set inside TI Stack kernel and you cannot revise it from application.

So how i can send a broadcast message to all sensors? Or i need to send unicast to all?

I would suggest you to use unicast.

In this question: e2e.ti.com/.../666300

The Suyash Jain say:
"You can use the beacon Payload to broadcast message in beacon mode. "

Suyash Jain Hector_r can you elaborate how to manipulate beacon Payload to broadcast message in beacon mode?

You can use the following APIs
ApiMac_mlmeSetReqUint8(ApiMac_attribute_beaconPayloadLength, uint8_t value); //set the beacon payload length
ApiMac_mlmeSetReqArray( ApiMac_attribute_beaconPayload, uint8_t *pValue); // set the beacon payload

Please note that after setting the payload, the payload will remain the same and you will have to reset or change the payload if you dont want the device to keep sending the exact same data in every beacon.

Also note that the beacon payload has a length limit of APIMAC_MAX_BEACON_PAYLOAD

So, how can we restore original beacon payload if we change it?

set the length back to zero

Where i can read the beacon payload on the sensor side?

I inserted the sensor code to read the payload on a new Beacon Notify Indication callback created on sensor.c. Is the best way to read the payload?
