How should I get the advertisement packet?

[sdi_kei]

Hello.

I am developing using nrf52832 (S132 v7.0.1, SDK v16.0.0).

During development, I was wondering about advertised packets.

I thought that the advertisement packet information would be included in the "scan_evt_t" structure when the advertisement was received, but there was missing information such as Preamble and Access Address.

How should I get the advertisement packet?

Is there a function to get it?

Also, if information is entered in the "scan_evt_t" structure, please tell me which information is entered in which place. 

Please let us know if you have any questions.

Thank you.

Why do you feel the need to see these?

Surely this is just low-level radio link stuff - not something for the application?

EDIT

I found this:

"Preamble: Used for internal protocol management. Advertising packets have 0xAA as preamble
 Access Address: This is always 0x8E89BED6 for advertising packets."

So they really are superfluous in an advertising event report ?

thank you for your answer.

No Preamble or Access Address is required when creating a communication with a peripheral.

In my opinion, if I got the information of the advertisement packet somewhere and put it in the structure, I felt that I could see the Preamble and Access Address.

As a confirmation, does the information in the advertisement packet enter the "scan_evt_t" structure when the advertisement is received?

Thank you.

 Here is the information from the advertisement packet you get from the SoftDevice: https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.s132.api.v7.2.0/structble__gap__evt__adv__report__t.html
