Hi, @Larry3
Could you please help me with more details about your implementation/project?
Our current SDK contains APIs to capture IQ, nonetheless, you will need to develop your own examples with those API's.
The API's can be found at the following path.
<installation path>\ middleware\wireless\framework_x.y.z\XCVR\MKW36Z
You can find the APIs to capture IQ in the dbg_ram_capture or the dma_capture files.
Besides, Would you mind to think about the method of Localization Based on RSSI Ranging?
If not, you can refer to this AN for details:
Best regards,
Christine.
