hello sir, i just bought this product
robotshop.com/seeedstudio-serial-bluetooth-module.html
my plan is to use a celphone’s bluetooth connection to connect to this bluetooth module which is again connected to a microcontroller, my problem is, is there anyway i can embed a program into the microcontroller to only accept commands from this certain celphone? like no other devices/celphones equipped with bluetooth capability would be able to connect to the microcontroller? is there any way i can get a certain unique ID of the bluetooth and embed it into the microcontroller and program it like it would only entertain commands if the ID of the devices’ bluetooth matches? thank you very much, if there is, how do i do that?
