C.23. S54: BD Address of Last Connected Device
This saves the Task2 BD address of the Bluetooth device connected most recently in a multiple
connection mode.
C.24. S55: BD Address of Last Connected Device
This saves the Task3 BD address of the Bluetooth device connected most recently in a multiple
connection mode.
C.25. S56: BD Address of Last Connected Device
This saves the Task4 BD address of the Bluetooth device connected most recently in a multiple
connection mode.
C.26. S57: Slave Disconnect Timeout (default 3)
This S57 register value defines the time period in seconds that a master unit waits in case a slave unit
does not receive the data sent from the master. For this time period, the master unit will not send data
to all slave units if any slave unit does not receive the data. If the slave unit does not receive the data
after this time period elapses, the master unit will disconnect the connection with the problematic slave
unit. The value should be greater than 0 and smaller than the Supervision Timeout(S37).
C.27. S58: MAX TX POWER (default 0)
This value describes the peak output power. Setting this causes rebooting and applying. (There can
be a little deviation depending on the each device.)

C.28. S59: Current Slave in Communication (default 0)
This value shows the current slave number in communication. The value is automatically stored when
the slave is selected for communication. This value can also be set by user so the master unit
connects to a specific slave to connect first in case the master unit reboots. The value range is 0~4. 0
means the maser unit never connected to a slave. The master will connect to a slave whatever
responses first.
C.29. S60: Reconnect Time Interval (default 5)
This value defines reconnect time interval in case a slave is disconnected in multiple connection mode.
The actual reconnect time interval will be the value multiplied by two in seconds. For example, if the
value is set to 5, the reconnect time interval will be 10 seconds. The value should be greater than or
equal to 5. The master unit will only try to reconnect when its mode is set to Mode1.
