CCS/CC2640R2F: Simplelink SDK project AoA_receiver How to change the Configuration Parameters of LocPktTab location

CCS/CC2640R2F: aoa_receiver - triggering rx AoA packet event

Part Number: CC2640R2F

Tool/software: Code Composer Studio

I'm using another BLE transmitter than the aoa_sender with a slightly different AdvData structure. The first 3 bytes are flags and cannot be changed. The rest of the packet has the same format as the sender_aoa AoA AdvData (meaning first 3 bytes are flags but byte 4 is the length, byte 6,7 Texas ID, 8 pkt ID, 6 bytes of padding and 17 bytes of '1's). I'm unable to receive anything during the AoA Scan at the receiver due to the mismatch in the AdvData bytes. Is there a way I can modify the aoa_receiver code to match the company ID at AdvData byte 6,7 and Packet ID at AdvData byte 8 to trigger the AoA packet event in RF core?

Thank you!

    Hi Hanne,
    I am uncertain if this is possible. Assigning one of the experts to comment.

    Hi,

    The RF core is expecting the first 5 bytes to be the specific payload shown in the aoa_sender project, and it can not be moved to a different location.
    can you specify your application needs so we can see if there is another way to achieve what you want?

    Hi,

    Thank you for your response! The application I'm working on requires access to the IQ samples from the AoA packet without using one of the TI CC2640R2F boards as a transmitter. My goal is to be able to use any BLE device that is transmitting the AoA tone in its Adv packets. The BLE transmitter I was using does not let me change the first 3 bytes of the payload to be what is expected at the receiver. I can only change the following 28. If the aoa_receiver code can't be changed to account for this, is there any other way you'd recommend to get the IQ from the AoA tone into a laptop for processing?

    Best,

    Hanne

    Hi,

    It's not possible in our 2.30 SDK solution. However, you can take a look at our CC2640R2 2.40 SDK, which takes I/Q samples of the CTE in connection packets.

    The Connection CTE packet format that our rtls_passive is looking for is BT 5.1 compliant format, which means eventually for whichever device(can be phones), as long as they implement BT5.1 spec, the rtls_passive will be able to get the I/Q and dump the data.

    Currently, there is no phones in the market that does this, so in order to start the evaluation, I would recommend you to take a look at our SimpleLink Academy training for AoA.
