AWR2243: Can profile be reconfigured dynamically or not

Part Number: AWR2243
Other Parts Discussed in Thread: AWR1642,

Hi,

About profile change dynamically, in SDK rl_sensor.h and interface control guide, it describes it is able to change profile dynamically without RF stop. But per my previous test on AWR1642 and some discussion on E2E, seems it is unfeasible, need to modify with RF stopped firstly. Here would like to get your confirmation, look forward to your reply soon, thanks.

@note 2: This API can be issued dynamically to change profile parameters.
* Few parameters which cannot be changed are
* 1. numAdcSamples
* 2. digOutSampleRate
* 3. Programmable filter coefficients in AWR2243/xWR6243/AWR29xx
* 4. The dynamic profile configuration settings are applied to HW at the end of the
* active frame boundary (start of the frame idle time). It is recommended to issue
* dynamic profile config API at the beginning of the active frame (during the
* chirping) to apply the profile changes for immediate next frame

BR,

Andy

    Hi,

    The information provided in rl_sensor.h is correct.

    The source code for this API is provided in the Device Firmware Package that can be downloaded from this link.

     

    www.ti.com/.../MMWAVE-DFP

     

     

    For AWR1xxxx devices please download Gen1 DFP. For AWR2xxx devices please download Gen2 DFP.

     

    The documentation for available commands is provided in the Radar Interface Control (RIC) doc provided in the package:

     

    C:\ti\mmwave_dfp_0#_0#_0#_0#\docs\mmWave-Radar-Interface-Control.pdf

    Please read the RIC to understand which parameters can be updated dynamically

    thank you

    Cesar
