CSI log file is empty

Open michaelp123 opened this issue 7 years ago • 7 comments

Hi Guys, I have successfully installed the tool, but having different issue:

I am able to ping successfully on both the router (hostapd @ 2.4 ghz, intel5300) and the client (samsung device) from each other. I also have set the rate to the HT rate (60 mbps). Ping is 100% success with zero packet loss. However the CSI file is empty and is unable to log anything. I couldn't find any solution that worked for me in this Q&A.

I would really appreciate any help in this regards.

Thank you,

I'm experiencing exactly the same problem:

  • Installation went OK
  • Connects to 802.11n no security AP (ZTE ZXHN H168N V3.1), HT rate, 40 MHz BW
  • Pings AP
  • No messages in the CSI terminal, CSI file empty. Can anyone please advise?

I'm using ubuntu 14.04 with kernel version 3.13

My teammate Samuel solve this problem by adding this in AP's hostap configuration file

# hostapd.conf
ieee80211n=1

but before this, you have to type this

dmesg | grep iwlwifi

to check if the output with a line that contains the string "loaded firmware version 8.24.2.12" If not, that's mean the modified firmware isn't loaded.

Thanks, @youngle37! I reverted to Ubuntu 12.04 and everything worked right from the start.

Hi @rt6n1 I've met the same problem. You said you revert to 12.04, still have you worked fine? regards

Hi @ljk8918,

CSI logging works fine. The only trouble is that data cannot be processed in GNU Octave that old, so I have to transfer the files to a PC running Ubuntu 16. This is indeed a nuisance.

It simply doesn't work on Ubuntu 14. I reverted to 12 and data logging worked fine. For processing I had to switch to a newer Ubuntu.

Regards, Milan
