Hi...Thanks for the quick reply..
By the way I'm planning to record or generate log that record RSSI values.
Any Idea..?? how can i generate logs of RSSI??
In getting started, on arduino expansion board i had recorded logs of temperature reading on SD card...
Can i generate similar log for RSSI values...through arduino?? or i have to stick to linux code for such processing??
I guess you could run a script that includes a line like this:
iwconfig wlan0 | grep -i signal >> signal_log.txt
And make a delay within the script so you add a line to signal_log.txt with a defined time parameter, also you could include in the script the date command so you have a knowledge on when you checked the RSSI, it would look like this:
date >> signal_log.txt iwconfig wlan0 | grep -i signal >> signal_log.txt
And its out put should look like this:
