Dw3000 pdoa and phase


I get the pdoa info, and aslo want to get the every anttenna phase info, so set the pdoa mode 3, then try to get the Sub-register 0x0C:08 – STS_POA and Sub-register 0x0C:10 — STS1_POA, the two value subtract, compare with the pdoa value, It is found that most of the time the value will vary by about 200. Sometimes the difference is about 2 times.

could you please share what type of hardware you are using? Is it an evaluation board from Qorvo or decawave?

Have you solved this problem? I also want to calculate PDOA by the difference between the POA of two separate antennas. I am not able to the get the constant 200 difference like yours. The difference between the PDOA from dwt_readpdoa() and my calulcation is random.

have you solved this problem?
