Command Responses
AT+WASR=2
Note: Get the Auto Shutdown features status
of all UART ports
+WASR:0,1,24,6
OK
Note: There is only one UART port listed because currently
only UART1 supported the Auto Shutdown feature.
AT+WASR=1,1
Note: The Auto Shutdown feature is activated
on UART1 using default GPIO and t1
OK
AT+WASR=2,1
Note: Get the Auto Shutdown feature status of
UART1
+WASR:1,1,24,6
OK
AT+WASR=1 +CME ERROR: 560
Note: Auto Shutdown feature already enabled
AT+WASR=0
Note: The Auto Shutdown feature is
deactivated on all UART ports
OK
AT+WASR=0 +CME ERROR: 560
Note: Auto Shutdown feature already disabled
AT+WASR=1,2 +CME ERROR: 3
Note: out of range.
AT+WFM=1,”SIM2VONLY”
AT+WHCNF=3,1
AT+CFUN=1
Note: Activate the External SIM Switch feature
AT+WASR=1
Note: Enable Auto Shutdown feature with
current parameters setting
OK
OK
+CME ERROR: 501
Note: GPIO allocation error because External SIM Switch
and Auto Shutdown feature shares the same GPIO.
6.4.6 Notes
After the Auto Shutdown feature is enabled, the users are not allowed to alter the
GPIO, which is dedicated for the Auto Shutdown feature, status by mean of AT
commands (such as +WIOM, +WIOR, +WIOW) or Open AT ® IO APIs under any
circumstances. If the user tries to change the status (value or direction) of the
dedicated GPIO, an error will be returned.
Once the Auto Shutdown mode is activated on the specified UART (e.g. UART1), no
AT command will be received by the Wireless CPU ® (as DTR is set to low) through
that UART port. When the Auto Shutdown feature is disabled with AT+WASR
