I am trying to get rssi on Jetson TX2. I used the function ioctl, but it just threw out error “Invalid argument”. I also tried to use other requests in the linux/wireless package, but all threw out the same error. It can connect to a wifi network normally, but when I ran iwconfig, every item showed “no wireless extensions”.
ifconfig returns eth0, l4tbr0, lo, usb0, usb1 and wlan0 normally.
0: bluedroid_pm: Bluetooth Soft blocked: yes Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: no 2: brcmfmac-wifi: Wireless LAN Soft blocked: no Hard blocked: no
I am not sure what other commands may help solving the problem. I have tried rebooting, but that made no sense.
Thank you for any ideas/assistance.
