WiFi_MaP

An ESP32 and FlipperZero wifi mapping

---

Check the ESP32 side at: esp32-wifi-map

And do not forget to have both sides on the last version.

Install, etc.

Clone this repo at applications_user/ folder under flipperzero-firmware

$ git clone git@github.com:carvilsi/flipper0-wifi-map.git

Build and flash

$ ./fbt launch APPSRC=wifi_map

Logs

$ minicom -D /dev/ttyACM0 -b 230400

Connection FlipperZero and ESP32

Flipper Zero GPIO	ESP32
GND	GND
RX	TXD GPIO_17
3V3	3V3

Collected Data

WiFi_MaP, by now, saves the collected data on a kind of CSV formated file, like:

AP hash;Distance (meters);AP auth mode;Time from start (seconds)
163976e1;61.90;4;68
f8fe611;74.99;3;68
134a1d9f;74.99;3;68

6cb4288c;68.13;4;71
69479d2d;74.99;5;71

Every time that WiFi_MaP starts adds the date to the file surronded by hash signs, then starts to add the collected AP data separated by ';'. The maximun AP that scans is 20. The data is:

AP name hashed	distance to AP (meters)	AP auth mode (1)	seconds since the scan started (2)
9fac872f	1.96	3	18

Notes

• (1) -> Table of ESP32 AP WIFI Auth Mode wifi_auth_mode_t

Open	WEP	WPA_PSK	WPA2_PSK	WPA_WPA2_PSK	ENTERPRISE/WPA2	WPA3_PSK
0	1	2	3	4	5/6	7

• (2) -> It's the time in seconds that the ESP32 module is connected to FlipperZero

Plot and Process Colected Data

If you want to plot and process the collected data from your warwalking session please check flipper0-process-wifi-map-data repo

---

TODOs

• Generate one file by session, filename with date and time.
• Add headers to CSV.
• Add interaction to reset time on ESP32 side
• Add navegator; basically with previous collected and processed data, get my current locations

---

Note: main branch works with latest version of FlipperZero firmware, 1.0.1 (in the moment of writting this). If you want to have this app running with a firmware version < 1.* check the legacy-previous-API-1 at the repo.
