CC2652R: Testing AOA without RTLS UI

Part Number: CC2652R

Hi,

      Is RTLS UI necessary to testing AOA? I mean, some customers want to get AOA data without UI. Because for realistic application it is difficult to bring a computer with RTLS UI all the time. So how to gather and output the data without a computer?

BR,

    Hi,

    RTLS_UI is not absolutely required to get AOA. You can also use the Python scripts included in your SDK.

    Hi,

    But it still needs a computer, right? Think of a scenario that just have launchpads and AOA boards, no computer. How can i get the AOA data? Is it possible to send these data out to another MCU for check and review?

    Hi,

    Short answer: we do not provide any stand alone AOA example.

    That being, the python scripts provided do the following for you:

    • when using Master + Passive (+ Slave), the script handles the transmission of the seed between the Master and the Passive
    • the script configures the device(s) through UART
    • the script receives the AOA or IQ data via UART (and stores the data)

    As a result, especially when only using a Master + Slave example, it is fairly easy to not use a computer.

    To finish, the customers should not think that AOA is a plug and play technology. I mean, as required by the BLE spec, the CC26X2R provides the IQ data measured. This IQ data can then be interpreted as an AOA. All the algorithms and know-how required to have a precise AOA are not provided (only a few examples are provided).

    Best regards,
