First, I would suggest you to create connection from computer to microcontroller just like what is being done in PR6A. For DIY project, we just show the basic functionality of a project, not the whole complex project as there are more complicated project involved. In PR6A, the microcontroller will be a slave, thus the connection request is being done by computer. In other words, sending AT command is not necessary for microcontrolller.
In your case, if you like to make a microcontroller as a host, you will need to send AT command with the correct Bluetooth Address of slave. Try to get the connection up first with computer to computer, and further change to computer to microcontroller and finally microcontroller to microcontroller. Good luck!
