Handling serial disconnect

[alexcroox]

I'm using this with a Bluetooth module and everything is working great. I'd like to be able to detect when the BT serial loses connection though so I can stop my robot from moving, is this possible?

I Believe it's best to use a timer or some kind of timeout function.

There is no way to know if bluetooth has lost the connection other than
using system apis on a host computer.
If you do two-way-timeout it will be much better.

For example on your host computer software setup a timer for 500ms. and on
the arduino use milliseconds in a loop or so.
Then you might know it has lost connection.
