Uses an ESP01 coupled with I2C cheap Oled display. Indicates if you are near or far and displays vitals RSSI and quality of signal. Code is a bit of a hash up. Simply proof of concept.

Enjoy.

Do you mind if I test your code out ?
How do I wire up the circuit?
I didn't see any circuit diagram in the extracted .rar folder.
I am about to order a OLED display online, I want to try your design with a cantenna setup to increase range further and make it more directional.

Please go ahead and make one, the circuit is simple, GPI0 and GPI2 are used for the Oled display, I2C SDA and SCL make sure you get the same display, not an SPI one will be no good.

All the normal apply's to the ESP, Pull ups must be used on GPIO pins, I will try and knock up a circuit if I get a little more time and you get stuck. Should be pretty straight forward. You could alternatively use one of the ESP12 dev boards on Ebay with RGB led on as everything is in place. The code will work the same on this as ESP01.

The Cantenna sounds cool, I was a RF design engineer have made many transmitters over the years, upload pictures when you get a chance would love to see finished version.

I may knock up some PCB's although these will use an ESP12 and Oled for other requirements, push buttons etc, would allow you to scan find the SSID and then hit track. this will be version 2 I think.

Enjoy buddy
