Part Number: IWR6843AOP
Other Parts Discussed in Thread: IWR6843

I use IWR6843AOP on ROS2 and now I try to config them. I want to max a range of 50 meters.
I have a problem to config them. Could you please share with me the config files or example files to config?
Or suggestion value for setting them.

Have you experimented with the Out of box demo and the mmWave Demo Visualizer? The visualizer creates cfg files for your desired settings which you can download and apply to a ROS application.

Yes, I have experimented on

https://dev.ti.com/gallery/view/mmwave/mmWave_Demo_Visualizer_IWR6843AOP/ver/1.0.0/

and

https://dev.ti.com/gallery/view/mmwave/mmWaveSensingEstimator/ver/1.4.0/

The first link, It hard to connect, and sometimes I get a config file but it can't use to config them in my system.
The second link, I load config and convert JSON to use for config them but not work too.

Now I just want to ensure I can set the parameter max rang for using.
I want only some examples to test it can to do.

This is file from first link profile(2).cfg

After set data port doesn't have anything to send out. That makes I don't know what wrong with this.

Addition : I use rev2

Now I have OK about the config file from link https://dev.ti.com/gallery/view/mmwave/mmWave_Demo_Visualizer_IWR6843AOP/ver/1.0.0/
But I have some questions because some config from that link can't demo too.
1. Can use the only 1tx for improving range resolution? (I have tried to config but don't get data)
2. Spec of IWR6843AOP/rev2. What range to detect object? (I think it can over 50 meters but the demo web can set the max at 50 meters)
3. Can change start frequency?

Replying to your questions in order.

1. Could you please provide more details on why you are not getting the data? Have you selected the 4RX, 1TX option from the Antenna Config drop down box in the visualizer?

2. Please try settings in the visualizer, you can adjust the depth of the sensor in the top left in the plots tab.

3. If it is not selectable to change the start frequency from the demo, it may not be advisable to do so. You can however modify the config by downloading it with the "save config to PC" and upload and start sensor from the plots tab with button "load config from PC and send"

1. Yes, I do that but after send config to mmDevice didn't have a data plot out. Now I have IWR6843/rev3 and use visualizer for SDK.3.4 can use only 1 TX.

Thank you very much
