BOOSTXL-AOA: Measurements and future developments

BOOSTXL-AOA: New 3.20 SDK and possible merge of Node Manager / RTLS Passive / RTLS Master on one board

Part Number: BOOSTXL-AOA

Hello,

I would propose the AoA + ToF estimators running together for our future products. Just a few questions:

Currently TI system is composed at least by:

  • 1 x Node Manager
  • 1 x RTLS Master
  • 1 x RTLS Passive
  • 1 x RTLS Slave.

Our application should use only 2 devices. 3.20 SDK implements BLE 5.1 but TI is currently supporting a system with Master, Passive and Slave. Do you know when SDK with the usage of only 2 devices will be released?

Do you think it is feasible to develop by ourselves only one firmware running on RTLS Passive (implementing Master as well)?

Could be the Node Manager moved on the new Master/Passive board?

Thank you

Luca

    Hi,

    We are working on getting master to also to I/Q sampling, this should be ready in Q3.

    It's not possible to merge master and passive into one example due to the radio patch used for master and passive are not the same.

    You can move the node manager functionality on chip but you will have to do it yourself.

    Thank you,

    since the passive board with antenna arrays will sample I/Q for calculate AoA, why master will get I/Q sample in the future? Do you mean the master will handle antenna array in the future and it will run as a passive as well?

    Hi,

    I just realized I did not ask you which device you are using.

    If your whole system is CC26x2, then in Q3, the rtls_master will support I/Q sampling and does the antenna switching when it receives AoA packets. In this case, you don't need the passive anymore if you only want to use 2 devices to do AoA.

    If your whole systems is CC2640, then you will always need 3 devices as rtls_master is only responsible of establishing a BLE link and request rtls_slave a send AoA packets.

    Hi,

    I have been using CC2640 till now. I am switching to CC26x2 in order to get benefits from using only two devices in Q3. In this way AoA e ToF could run at the same time, isn't it?

    Thank you

    Yes, if you are using CC26x2, then you can now run ToF and AoA at the same time. (AoA during connection events and ToF in between connection events).

    And in Q3 you will be able to only have 2 devices to run AoA when you are using CC26x2.
