[WCNCR00158507] misc: add noise histogram feature
[Description]
Add noise histogram feature, needs the corresponding firmware
Usage:
1. Start collection (Disable power saving)
iwpriv wlan0 driver "SET_CHIP KeepFullPwr 1"
iwpriv wlan0 driver "noise_histogram enable"
iwpriv wlan0 driver "noise_histogram get"
2. Reset noise histogram to 0 (Optional)
iwpriv wlan0 driver "noise_histogram reset"
3. Stop collection (Enable saving mode)
iwpriv wlan0 driver "noise_histogram disable"
iwpriv wlan0 driver "SET_CHIP KeepFullPwr 0"
4. Noise histogram format
keira: # iwpriv wlan0 driver "noise_histogram get"
wlan0 driver:
Power > -55: 0
-55 >= Power > -60: 1
-60 >= Power > -65: 79
-65 >= Power > -70: 8874
-70 >= Power > -75: 11736
-75 >= Power > -80: 1863
-80 >= Power > -83: 1613
-83 >= Power > -86: 12429
-86 >= Power > -89: 8874
-89 >= Power > -92: 3987
-92 >= Power : 249502
5. Works when AP is not connected
Test:
1. Sanity check: WiFi scan/connection OK
2. If not use the corresponding firmware,
"noise_histogram get" will show 1 time command timeout log.
This is expected due to no corresponding event in old firmware.
