My Bluetooth Autostart made with a BlueFruit Feather board. https://thealaskalinuxuser.wordpress.com

bluefruit_autostart's Issues

Range is rather limited, at about 30 feet.

Due to the board being a LE (Low Energy) board, with no external antenna, the range of communication with the autostart is rather limited. It appears to work out to about 30 feet.

Voltage detection verses tachometer to determine if vehicle is started.

Using the voltage off the battery/alternator is great to determine that the engine is running IN BETWEEN cranking attempts. However, it will not tell the board to stop cranking during starting, because when the engine starts, the starter is running, which draws the voltage below the 13 volt threshold. It may be better to figure out a way to use tachometer instead of voltage for future builds.
