IWR1843: High_Accuracy_Visualizer available for IWR1843

Hi Alec,

Thanks for your help.

Customer modified the 16xx High Accuracy Demo to support on IWR1843. But he can't get the correct result. It's about 6cm deviation and there is no FFT output. 




Thanks.

Shine,

On the first piece, there is an offset based on the signal propagation delay through the tx and rx antennas, which will vary based on PCB/EVM design. We would recommend that customer takes this and calibrates for this offset once on their design and then apply it to all devices. In regards to the plot, can you check to see if the TLV is coming out via serial? This will help to narrow it down if there is an issue in the visualizer or in the firmware migration to 1843. 

Best Regards,
Alec

Hello Alec,

Customer can't use the GU, so he get below data from Serial Debug Assistant.

Hello Shine.

We are discussing this internally and will get back to you as soon as possible.  Has the UART stream been parsed and see what information is contained in the range profile TLV?  In addition, did the customer try flashing the 16xx High Accuracy Lab on the 1843 device and see if the visualizer worked?

Sincerely,

Santosh
