Other Parts Discussed in Thread: CC2650

Hi,

I am using the sample code SimpleBLEBroadcaster in TI's BLE stack inorder to implement a BLE broadcaster in CC2650.

But, when I try to modify the payload, I am getting junk data in the receiver.

Could you please tell me the correct method to populate the payload.

I am currently populating the payload values into an array inside SimpleBLEBroadcaster_init.

Thanks in advance!!!

Hello. Advertising data is set with the GAPROLE_ADVERT_DATA parameter. By default, the advertData[] array is used to set this parameter in simple_broadcaster.c.

Hi,

I tried to modify the advertData[] array, but still the custom defined values appear in my receiver. The array is not getting modified with newly populated values.

Is there any solution?

What do you mean by "custom defined variables appear in my receiver?"

I would recommend stepping through the GAPRole_SetParameter() function to verify you are setting the parameter correctly.

It could also be a problem in your receiver. I would take a sniffer capture to verify what is actually being advertised.
