Part Number: AWR1843BOOST

We are using automotive lab demo mrr with AWR1843Boost, is it possible to control RF/Analog SS transmit chirps?

In some cases, we need radar sensor stops sending chirps to prevent interfering with some other important wireless communication. It is of course can be done by disconnect the power, but I would like to know if there is a method in Firmware side.

Thanks

Hi,

There is an API on the firmware package that lets you to stop sensor from transmitting frames. You can probably check that out at: C:\ti\mmwave_sdk_03_05_00_04\packages\ti\control\mmwavelink\src\rl_sensor.c "rlSensorStop" API. Please do go through this path and API and let me know if this solves the issue.

Please let me know if you have any questions.

Thanks and Regards,

Akshay.

Hi Akshay,

Thank you very much. I tried this call:

rlSensorStop(RL_DEVICE_MAP_CASCADED_1)

It seems work. Can you please check if the deviceMap parameter (RL_DEVICE_MAP_CASCADED_1) is correct option in above call for stoping sending chirp?

Thanks Regards

Hi Lei,

Yes it is the "RL_DEVICE_MAP_CASCADED_1" device parameter to be chosen for stopping chirps being sent as this would power down the BSS alone as shown in snip below from: C:\ti\mmwave_sdk_03_05_00_04\packages\ti\control\mmwavelink\mmwavelink.

Let me please know if you have any questions.

Thanks and Regards,

Akshay.
