Listing 9: wpa_supplicant.conf
Then run the wpa_supplicant daemon using the configuration file:
To configure the IP address through DHCP:
The “
iwconfig mlan0
” command can be used to display parameters and statistics of the wireless
network interface.

Driver debugging
Driver debugging is provided via the kernel print function
printk
and the
proc
file system. The driver
states are recorded and can be retrieved through the proc file system during runtime. The following
files containing the debug information are provided (the actual location is dependent on the Linux
kernel version):
•
/proc/mwlan/config or /proc/net/mwlan/config
•
/proc/mwlan/mlanX/info or /proc/net/mwlan/mlanX/info
•
/proc/mwlan/mlanX/debug or /proc/net/mwlan/mlanX/debug
☞
mlanX is the name of the device node created at runtime. Other possibilities are uapX and wfdX
for the acces point and Wi-Fi Direct interfaces respectively.
Debug messages are also printed to the kernel ring buffer through printk calls. These messages can
be accessed raw using the
/proc/kmsg
interface or by the
dmesg command. Alternatively, this can be
handled by more advanced logging facilities.
4.7.1
Compile-time debug options
The extent to which debug messages are available for printing at runtime is controlled by the
CONFIG_DEBUG
variable in the driver's Makefile. The
CONFIG_DEBUG
variable can have the following
values:
•
n: debug messages are disabled and not compiled into the driver module
•
1: all kinds of debug messages can be configured except for MENTRY, MWARN and MINFO. By
default, MMSG, MFATAL, and MERROR are enabled.
•
2: all kinds of debug messages can be configured
4.7.2
Runtime debug options
Once debugging is enabled in the Makefile, debug messages can be selectively enabled or disabled at
runtime by setting or clearing the corresponding bits of the
drvdbg
parameter:
ctrl_interface=/var/run/wpa_supplicant
ap_scan=1
network={
scan_ssid=1
ssid="MyAP"
key_mgmt=WPA
-PSK
psk="12345678"
}
