+KSLEEP
Configure UART1 power management (sleep mode entry conditions)
Configure UART1 power management, indicating under which conditions the module will
enter sleep mode.
Password required:
No
Persistent across power cycles:
Yes
Requirements:
•
To have DTR control sleep mode (<mngt>=0), AT!RIOWNER=0 must be used before
using +KSLEEP.
Notes:
•
Controls only UART1 power management; does not affect USB AT command port.
•
When KSLEEP=1 and the module is in sleep mode, the user must input a character to
wake the module. When the module is awake, AT commands can be input as normal.
Usage:
•
Execution:
AT+KSLEEP=<mngt>
Response:
OK
Purpose:
Set the power management configuration.
•
Query:
AT+KSLEEP?
Response:!
+KSLEEP: <mngt>
OK
Purpose:
Indicate current power management configuration.
•
Query list:
AT+KSLEEP=?
Purpose:
Return a list of supported <mngt> values.
Parameters:
<mngt> (UART1 Power management configuration)
•
0—Module will not enter sleep mode when DTR is active (low level). If DTR is inactive,
module enters sleep mode:
•
(WP8548/WP75xx) after 5 seconds
•
(WP76xx/WP77xx) once all wakeup sources are released.
Note: DTR must be active to send AT commands.
•
1—Module enters sleep mode automatically based on an internal timer (default
2 seconds; if a different default is required, it must be configured in the PRI)
•
2—Module never enters sleep mode (regardless of DTR state)
