While evaluating M5Stack for a sidehustle project I created a proof of concept which needed to access wifi network, query an API and download an image. Wifi geolocation which displays a static Google map was a perfect fit. Here are some notes about it.
The popularity of WiFi networks has been rising rapidly during the last 15 years. In urban areas hotspots are ubiquous. These hotspots together with clever trilateration algorithms provide a cheap way to find out your or someone elses relative location.
While working on Whereami I got interested on how Apple location services work. I know it is
locationd since Little Snitch keeps blocking it. Tinkering with MITM proxy revelealed interesting results.
