WiFi Scanner Module for FlipperZero based on ESP8266/ESP32 (results with ESP8266 much better than with ESP32)
This module will help you in finding specific access point physical location.
Proto WiFi scanner module

# Controls On scan page: * UP - move list up by one * DOWN - move list down by one * OK (short press) - enter monitor mode * OK (long press) - scan again * BACK - exit app
In monitor mode: * OK (long press) - scan again * BACK (short press) - return to scan page and scan again * BACK (long press) - exit app

Compile and flash firmware on Wemos D1 Mini
Install EPS8266 board version 2.7.4 for Arduino IDE. I had issues with higher versions.
Compile firmware for FlipperZero with new application
If you want compile for Dev Board then enable FLIPPERZERO_DEV_BOARD_V_1 in code. Same goes to ENABLE_MODULE_POWER, ENABLE_MODULE_DETECTION
Use next schematics to solder the WiFi Scanner board for FlipperZero

I tested all the things on a test bench with Wemos D1 and all was good. When I soldered protoboard with Wemos D1 mini pro I started to receive exceptions. It seems for some reason Wemos D1 mini doesn't run well on FlipperZero 5V. To fast solve the issue I've added an AMS1117 voltage regulator on 5V to drop it to 3V3 and feed the module.
