How receiver know the AoA packet is received? by preamble?

With a packet ID, please review the API transmitterInitAdvData in AoA.c

What's the AoA packet receive process before PDU is received? add delay?

When the receiver gets AoA packets, the RF core will trigger an event that will lead to start the antenna switching (all of these are done prior to I/Q sampling). Then, the RF core will start sampling the I/Q data at the beginning of the AoA tone (PDU) and the sampled data will be stored at the RF RAM.

For more information, please review this AoA SLA dev.ti.com/.../ble_aoa.html

Hopefully this helps.

Dear David

Thank you so much

May I ask one more question?

How do we know the Adv. packet we receive is the 1st packet from the sender and not the one from multipath?

Or, what's the method we are using to avoid the multipath?

For the TI CC2640R2 receiver, does the receiver scan the adv. packet all the time?

So, we can make sure we always receive the very 1st adv. package and eliminate the any duplicate package after for the multipath issue.

Regards,

Andy
