Example of a Master Discovery/Connection Sequence From power up and no connection:
809 University Avenue
1) Perform an Inquiry to obtain BT_Address (unless it is already known).
2) Store the remote address just found.
3) Connect.
4) Send /Receive data.
Using PIOs/ Switches for Auto-pairing and Auto-Connection

connects to it.
To enable cable replacement, set PIO3 high on slave, PIO3 + PIO6 high on master.
Once paired, PIO3 = low on both devices (so re-pairing with another roving device does not
occur)
( PIO3 = DIP Switch 2, PIO6 = Dip Switch 3 on Firefly and Blueport )

string is defined in the stored parameters.
low
default slave, no special function.
slave, changes COD to 0x0055aa for auto pairing.
auto master, uses STORED address....... does not try auto pairing.
Function
auto master, auto pairing, looks for first device with 0x55aa stores it, and
