Part Number: LP-EM-CC2745R10-Q1
Other Parts Discussed in Thread: CC2745R10-Q1, SYSCONFIG

Tool/software:

Hi,

I would like to know

1) I want to estimate distance using RSSI and  PBR & RTT methods. Is the support available in its SDK / framework for the LP-EM-CC2745R10-Q1 board?

2) Does TI has Bluetooth Sniffer/ Bluetooth protocol analyzer?

3) Is multiple antenna booster pack is available to enhance the accuracy of BLE channel sounding.

4) If there are any recent developments with respect to channel sounding in the CC2745R10-Q1 evaluation board.

5) How do we access the SDK of the above mentioned board?

    Hi,

    1) The RSSI is supported. Regarding the PBR and RTT, only PBR is supported from SDK 9.10. Our Channel Sounding technology is based on PBR only for the moment.

    2) Yes, TI has a Bluetooth sniffer.

    3) We have dual antennas booster pack for channel sounding, but they are not for sale yet. It might be for sale in the future.

    4) We use the above booster pack with the evaluation board to improve our channel sounding technology.

    5) The SDK supporting channel sounding can be found at that link.  As I said, channel sounding feature is supported from SDK 9.10.

    Best regards,

    Thanks for the adequate reply.

    Kindly clarify one more query;

    Does the SDK help in providing IQ data ?

    We need access to unfiltered IQ data.

    The SDK can provide unfiltered IQ data.

    To do so, go to sysconfig of "car_node" example, then RF STACKS/BLE/Channel Sounding Configuration. Set "Channel Sounding Results Mode" to "Distance + Raw Results". In the Python script "ble_device_car_node_with_distance.py", line 384 change cs_proc_enable's argument named "wait_for_raw_events" to true.
