I find myself in need of a device which apparently does not exist, so I have have undertaken to build it myself.
After just having my motorcycle robbed at gunpoint I realized the need for a device that will shut my vehicle down if we become separated. My idea is to use an Arduino with the HC – 05 Bluetooth board. The idea is that I will carry a phone which has been paired to the HC – 05. The Arduino will periodically check the condition of the HC – 05, and see that it is in the paired state. If the device is still paired (I and my telephone are still nearby) it will maintain a relay closed which will allow the engine to run. If the HC – 05 becomes unpaired (I and my telephone are no longer near the vehicle), the relay will open and the engine will stop. Yes, I realize this is based on the assumption that they also don't steal my telephone when they steal my motorcycle. They usually just grab the bike and go.
I have looked into the specifications of the HC – 05, and it looks like the way to go for the main loop of the program is to keep checking the connection status of the HC – 05 Bluetooth connection via an AT command which reports back the connection status.
This is my first time using Arduino, so I have no experience with it or the HC – 05.
I would greatly appreciate any input or ideas anyone has, especially anyone with working experience with something similar involving HC – 05.
Thank you very much in advance.
