<div dir="ltr">Andrej,<div><br></div><div>Thank you for the quick reply. I tried your solution and also added filter to filter the tags which I want instead of logging everything from the circular buffer. Currently, this should work fine for me and I am planning to add these commands to init.rc file so that they can start upon phone boot.</div>
<div>I identified the place where the logging daemon service is started in init.rc file. Below you can see part of init.rc file where the shell process is spawned. </div><div><br></div><div><div>## Daemon processes to be run by init.</div>
<div>##</div><div>service ueventd /sbin/ueventd</div><div> critical</div><div><br></div><div>service console /system/bin/sh</div><div> console</div><div> disabled</div><div> user shell</div><div> group log</div>
</div><div><br></div><div>I have 2 questions:</div><div>1) Do you want me to add the logcat commands in any specific place in init.rc file?</div><div>2) For my next steps, I am planning to read and write some information like SSID name, freq etc in a file other then wpa_supplicant.conf file from within the wpa_supplicant daemon service. That's the reason I asked to log events directly form wpa_supplicant in my first email.</div>

Example the file could be logged in /data/misc/wifi/supplicant_log.txt. I shall later parse this log file and gather some information.<u></u><u></u></p>
