SENA Parani-SD1000U - Manual (Page 44)

B.23. S48: Low Power Max Interval (default 5000)
This is the max interval value to use low power mode, which is set to 5000 initially. (5000 x 625μsec =
3125msec)
B.24. S49: Low Power Min Interval (default 4500)
This is the min interval value to use low power mode, which is set to 4500
initially. (4500 x 625μsec =
2812msec)
A small interval increases power consumption, a large interval increases latency.
B.25. S52: Low Power Timeout (default 5)
This is the low power timeout value, which is set to 5 initially. (5sec)
During no data transmission in the timeout, Parani-SD will be in low power mode to save the power.
Therefore, it takes a few seconds to wake the Parani-SD out of low power mode.
B.26. 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.
B.27. 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.
B.28. 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.
B.29. 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).
B.30. 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.)
