RTOS/CC1352P: Security Key exchange at MAC layer in FH mode or NOT?

Part Number: CC1352P

Tool/software: TI-RTOS

Hi,

CC1352P - FH mode - Collector code,

In the programming while PC and PA (Frames) exchanging happening in between collector and sensor. After that AES encryption is used at network layer for exchanging the data.

so as a programmer if i want to see encrypted data then how can i check using UART?

Or with Packet Sniffer i can see the encrypted data in the air?

how many ways are there to test the encrypted data?

Hey Anil,

You can use the packet sniffer and see encrypted data and see decoded dat aon the Code.

Hello AB,

I am using FH mode code, and sensor code is fixed channel. So in packet sniffer I used the channel 0 with all configuration.

But on Wireshark I am not getting anything. So for this I used one document and I already talked with yaiki chain, but it's not get resolved. In ti Wireshark packet sniffer - device config - in packets I am unable to see the packet or in Wireshark tool also I am unable to see any kind of data.

So on which channel I need to check , because of fixed channel I fixed as a channel 0.

Can you suggest more on this.

Regards,

Anil.
