Rev. 8 May.12 Proprietary and Confidential 81
+WHCNF
Supporting chipsets:
• MDM6200
• MDM6270 (min f/w rev:
S0_0_2_1)
• QSC6270 (min f/w rev:
S0_0_2_1)
Activate/deactivate modem hardware features
Activate, deactivate, or return the current operating state of hardware features (LED,
SIM, and UART).
Usage:
• Execution: AT+WHCNF=<type>, <mode>[, <uartgroup>[, <uartlinedcd>[,
<uartlinedtr>[, <uartlinedsr>[, <uartsleep>]]]]]
Response: OK
Purpose: Activate/deactivate the specified hardware <type>.
• Query: AT+WHCNF?
Response:
+WHCNF: <type>,<status>[,<resetFlag>]
or +WHCNF: <type>,
<status>,<resetFlag>,<uartgroup>,<uartlinedcd>,<uartlinedtr>,
<uartlinedsr>,<uartsleep>]
...
OK
Purpose: Display the current activation state and settings for each hardware
feature.
• Query List: AT+WHCNF=?
Purpose: Display valid execution formats and parameter values.
Parameters:
<type> (Hardware functionality)
• 1 = LED
• 4 = InSIM switch (MDM6270/QSC6270 only)
• 6 = UART
• 7 = Buzzer (MDM6200 only)
<mode> (Requested operation)
• For <type = 1> (LED)
• 0 = Deactivate
• 1 = Activate
• 2 = Interrogate status (Note: The execution response returns the current
operating state of the <type>—deactivated or activated. The Query format
can be used to return the same information for all of the hardware types at
one time.)
• For <type = 4> (InSIM switch)
• 0 = External SIM privileged (Default)
• 1 = External SIM only
• 2 = Internal SIM only
• 3 = Get inSIM switch selected mode
• For <type = 6> (UART)
• 0 = Deactivate
• 1 = Activate
• 2 = Interrogate status (Note: The execution response returns the current
operating state of the <type>—deactivated or activated. The Query format
can be used to return the same information for all of the hardware types at
one time.)
