The address is a 12-digit hexadecimal number. It can also be found on the Pmod BT2's label as the MAC ID. Once the slave's device address is known send the command "SR,<address><cr>" in order to save it to memory. For example if the slave's address was 00066676ABCD you would enter "SR,00066676ABCD<cr>".
