 1 | A Tesla scanner for ESP32 devices. (with bluetooth) 
 2 | 
 3 | Tesla uses the same device naming convention for the bluetooth door lock or whatever for all of their vehicles, 
 4 | first letter is "S" and the eighteenth is "C".
 5 | 
 6 | This program will constantly scan for devices in the area fitting that convention, and (in this case) flash the 
 7 | LED when one is found. Flashing speed/length is dependent on signal intensity, sort of war movie radar style.
 8 | It's a fun game when driving, but can become obnoxious in certain areas.
 9 | 
10 | You can of course modify this program to control whatever your little heart desires. 
11 | 
12 | Written in the Arduino IDE and uses several libraries included with the ESP32 boards.
13 | 
14 | For educational use only, we are not responsible for any use outside of education.

 1 | /* A bluetooth scanner for ESP32 devices to find Tesla vehicles and do things. Tesla in all their genious uses the same bt device naming convention
 2 | across all (truck included) vehicles, first letter "S" eighteenth letter "C".
 3 | 
 4 | I'm a codelet and this was written in the Arduino IDE, this particular version for an ESP32-CAM module. (POS, avoid)
 5 | Will flash the very bright LED when a Tesla is in the vincinity, altering speed/duration dependent on signal strength.
 6 | This can of course be modified to fit your device/desired action.
 7 | 
 8 | Uses the libraries listed below obviously, thank you to Neil Kolban and Evandro Copercini. Update to newest libraries
 9 | in case of errors.
