I am building a system for my car to communicate with my phone to start and unlock my doors. I ordered a BTM-182 board the other day and have been researching on how to communicate with it.
So my dilemma is I am unsure of the syntax for sending data to the bluetooth chip.
RIght now I have a command to find bluetooth devices: BlueTooth.print("ATF?"); delay(600000) // 60 seconds to find a device BlueTooth.print("ATA1"); //connect to the first device?
I am new to using AT commands. Is there any tutorials that would be helpful?
Right now I just want to find a device and have the board understand that something is connecting to it.
Thank you, Richard Wiseman
