CC1352P: How to select CSA on CC1352

Michael Wang

Part Number: CC1352P

Hi, I am working on Simple Peripheral example on CC1352P-2 LaunchPad for ADV_EXT_IND, I have two questions:

1. Is it possible for me to select CSA # 1 or CSA #2?

2. If possible, how to do it, I read "Channel Select Algorithm #2" on user's guide, but I didn't understand, could you provide detail info.

Thanks,

Michael Wang

I will assign someone to answer your questions. In the meantime, please provide information regarding what SDK version you are using.

This information is found here: Channel Selection Algorithm #2

1. CSA#1 is enabled by default in the stack, but can be disabled if you want to (I am not sure why you would do that though).

2. Refer to the Bluetooth specification for details.

CSA#1 is not the default, I imported the Simple Peripheral and run it, captured the ADV with SmartRF packet sniffer, got:

which tells me it is not CSA#1, am I right? Could you confirm CSA#1 is the default?

Thanks,

Michael

Your sniffer capture confirms that the documentation is not lying. CSA#2 is enabled by default.

Could you tell me how to set the default CSA?

I just like to figure out a way to set ChSel = 0 in ADV, could you tell me how to do it?

It is explained in the documentation I linked to earlier.
