Description

I wanted a really mobile setup to measure the RSSI for our installations of muenchen.freifunk.net. It should be easy to carry and easy to use.
As long it did not find a muenchen.freifunk.net node, it does display the number of surrounding Wifi nodes. When it did find one or more muenchen.freifunk.net nodes, it selects the one with the current highest RSSI and displays this via the NeoPixel ring. For the next 60 seconds, this node is fixed. If it is lost, the search starts from the beginning.
If you add a serial console all the found SSIDs and more information is available with 9600-8-n-1.

I added a new project, which does GPS tracking and logging to a SD card.

I updated the source code to introduce a watchdog timer, which catches issues in the WiFi subsystem

Still working on this, but the ESP8266 boards don't have GPS and GPS draws a lot of power too. We currently do long exposure shots to build a heat map

This project is screaming out for a GPS module and some data storage.
