you can still use the Slaves BT address and connect directly to it from a
remote Master.
Function: Configures Page Scan and Inquiry Scan Interval and Window for
disconnected slave devices in time slots.
Format: ATSW21,<psInterval>,<psWindow>,<isInterval>,<isWindow>
Parameters:
Factory Default: psInterval = 1024(640ms), psWindow = 512(320ms), isInterval =
1024(640ms), isWindow = 512(320ms)

TYPE :
REPLY:
psInterval: Page Scan Interval
psWindow: Page Scan Window

isWindow: Inquiry Scan Window
Requires a reset for the settings to go into affect.
ATSW21,4096,18,4096,18 settings will result in a current draw for an
unconnected slave of ~1mA average vs. 39mA average at default setting.
Which is 1%
ATSW21,4096,18,4096,18 settings along with enabling Deep Sleep Mode will
result in an unconnected slave current draw of ≈ 350uA average.
By lowering the window value, power can be saved at the expense of
possibly missing an inquiry or page. Since the host usually retries
automatically many times, the only downside is a delay in discovery or
connection time.
Integer Value 18 to 4096 (11.25ms to 2560ms)
Time [ms] = psInterval * 0.625ms
