bd467913 commented 4 years ago

Hi I'm trying to set monitor mode. I used the 'user_space' _monitorch.sh but without success.

thanks

JiaoXianjun commented 4 years ago

Could you show me the exact command with arguments and outputs?

You could also use: iwconfig sdr0 mode monitor

bd467913 commented 4 years ago

this is working but after i am getting the sdr0 up all is stack

ip link set sdr0 down iwconfig sdr0 mode monitor ip link set sdr0 up after this command the broad is stuck and i have to restart it

JiaoXianjun commented 4 years ago

Can you set a channel in 5GHz to listen? Such as, 36, 44, 48? iwconfig sdr0 channel 44

Current version might have some issue in 2.4GHz because SIFS in 2.4GHz is shorter. We are working on it. There will be new version soon.

bd467913 commented 4 years ago

i getting stack again in when it get to set the sdr0 up

JiaoXianjun commented 4 years ago

So, for monitor mode in 5GHz you never run it successfully? (Stuck immediately or after a while?). You are using the original version without modifying anything?

hostapd is successful?

JiaoXianjun commented 4 years ago

Before setting it to monitor mode, could you please run: service network-manager stop

bd467913 commented 4 years ago

Ok hostapd with the file configuration attached is working and i see the network when run the commands:

root@analog:~/openwifi# service network-manager stop network-manager stop/waiting root@analog:~/openwifi# sudo ip link set sdr0 down root@analog:~/openwifi# sudo iwconfig sdr0 mode monitor root@analog:~/openwifi# sudo ip link set sdr0 up root@analog:~/openwifi# sudo iwconfig sdr0 channel 44

this gets stuck

JiaoXianjun commented 4 years ago

Thanks. We will take a look ASAP after holiday.

How about this sequence? wgd.sh iwlist sdr0 scan iwconfig sdr0 channel 44 iwconfig sdr0 mode monitor

bd467913 commented 4 years ago

OK but you have to set sdr0 down, before setting the monitor mode after set it up again the device get stuck

i will wait after the holiday

Hello, I have fixed the monitor mode bug in the driver sdr.c. My test is OK.

Would you please just pull and regenerate sdr.ko by the make_all.sh script and see whether it is fixed at your side?

Thanks!

bd467913 commented 4 years ago

Hello, I have checked and it looks better for the 5Ghz. About the 2.4Ghz still sum problems, buy i understand that will be fix for it.

Also i checked and not all 5Ghz frequencies also not supported. Is there any chance to add more frequencies?

JiaoXianjun commented 4 years ago

Hi, for 2.4GHz monitor mode, actually it is related to another known issue that has been fixed internally. We will have some commits next week to fix it. After that, monitor mode should work for all bands.

For more 5GHz channels, could you please create another issue? I will close this one.

bd467913 commented 4 years ago

Yes Thank you for the quick response
