Question

My specific questions are:

• 1. How to change the debug level to MSG_DEBUG of wpa_supplicant in
     Android?
  2. Do I need to compile the wpa_supplicant to achieve this goal?
  3. How to view the logs?

I had tried to use these commands:

1. adb shell wpa_supplicant -c/etc/wpa_supplicant.conf -iwlan0 -d
2. adb logcat | grep -i "wpa_supplicant"

But these commands didn’t bring up MSG_DEBUG level logs.

I tried to use the conf file in /system/etc/wifi directory. i.e.

adb shell wpa_supplicant -c/system/etc/wifi/wpa_supplicant.conf -iwlan0 -d

But this give me an error:

mkdir[ctrl_interface]: Read-only file system

I didn’t find a workaround for this. How can I solve this?

Answer 1

in the wpa_common.c file,you can find the wpa_printf function output the debug log,you cant use MSG_DEBUG as a parameter,that’s you question 1 and 2
