Once Master connects to repeater the repeater will reply with CONNECT,00,BT_Master_Address and then
repeater will automatically connect to slave and reply with CONNECT,01,BT_Slave_Address. Several NO
ANSWER responses may display before connection to slave is completed.
Now the master and slave Bluetooth devices can send and receive data between each other through the
repeater Bluetooth device. Data entered at the repeater workstation will be sent to both the master and slave
units.
