Hi there,
I am currently on holiday and I have my bananapi with me and I was wondering if there was an application that when a new Wifi network is detected it will log it to a text file with its strength, lat long and name. Is this possible?
Yeah should definitly possible.
I know some kind of programm that shows Wifi networks in your range:
