Question about fetch the csi data

[JODE-HRK]

Hi, I am one of the Nexcsi users. Could you please tell me how to fetch the csi data both amplitude and phase? I used the sample['csi'], but the data seems not correct.

You should use the unpack function to change it to complex numbers. Once there you can use numpy amplitude or phase.

csi = decoder(device).unpack(samples['csi'])
