Does anybody have experience on a Raspberry Pi with Bluetooth?
I am exploring solutions to detect the presence of a bluetooth device (a smartphone) and then send a text message (SMS) to remind them to clock in to their shift. I think I could do this on a Windows or Mac with some MBS functions (which I have licensed) but it does not work in Linux or Raspberry Pi. A Pi is preferred due to pricing and physical size.
I would even consider "SHELLing" out to a some sort of command line tool and then process the result. A bit of Internet searching indicates some Bluetooth tools do exist for the Pi environment.
The data needed would be some unique identifier that I can associate with an entry in a database then create the text message.
