Collected Data

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

##### 20-9-2024_17:47:47 #####

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
f8a4985c	1.96	3	18

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

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.
