why some csi matrixs in csi trace are empty? #219

Open bboyzhou opened 8 years ago

bboyzhou commented 8 years ago

I installed Atheros-CSI-Tool-UserSpace-APP in two PCs,and I use three 5G directional antennas at TXD NIC:AR9380 OS:Ubuntu 14.10 I set the rate of sending packets is 100p/s, I found some (even all) csi matrixs in the csi trace are empty. Is the link very weak? I think not, because the RSSIs are similar whether the csi matrix is empty or not. Are there somebody else encounter the similar problem? I can't find the reason all the way.

Thanks!

@bboyzhou have you solved this problem? I have the same case. Specially, when I use three antennas router, there are 80% [].
