IQ sample capture - Side info count not incrementing #363

Open remydemy opened 10 months ago

remydemy commented 10 months ago

Hello, I'm trying to execute the IQ sample capture on my ANTSDR E310, but unfortunately the side info count is not increasing. These are the commands I execute:

cd openwifi
./wgd.sh
./monitor_ch.sh sdr0 11
insmod side_ch.ko iq_len_init=8187
./sdrctl dev sdr0 set reg xpu 1 1 // This command is mentioned in iq.md to capture self TX signal, but I'm not quite sure when I should execute it
./side_ch_ctl g

The result I then get is: 

loop 64 side info count 0
...

So the side info count remains at 0 and does not increase. What could be the cause of that?

Best regards, Emily

If you read our app note carefully, you should realize that you should not use 8187.
