<poweredLowlim>
<poweredHighlim>
This command is used to perform an antenna diagnostic check and display the results. The
current values of the primary and secondary antenna ADC readings are compared against the
limits specified by the AT+WANTLIM command to determine the status (NORMAL, SHORT,
OPEN) of each antenna.
Command Syntax: AT+WANTS
The +WANTS response displays the diagnostic status of the primary and secondary antennas as:
+WANTS: <primaryAntStatus>,<secondaryAntStatus>
<primaryAntStatus>
<secondaryAntStatus>

antenna to prevent damage to the modem. In this case, you must re-issue AT+WANT=1 to
re-enable power to the secondary antenna.

The ADC value below which the powered antenna is considered to be in a shorted
condition. Possible values are 0-255. Default is 0. Not applicable to the primary
antenna.
The ADC value above which the powered antenna is considered to be in an open
condition. Possible values are 0-255. Default is 255. Not applicable to the primary
antenna.
SHORTED (ADC value < low limit)
NORMAL ( low limit <= ADC value <= high limit)
OPEN (ADC value > high limit)
SHORTED (ADC value < low limit)
NORMAL ( low limit <= ADC value <= high limit)
OPEN (ADC value > high limit)
The +WANTS unsolicited message is reported to the application for a change in
the diagnostic status of one or both of the antennas. The AT+WANTPOLL
command is used to specify which antenna is checked and the interval between
checks. The AT+WANTLIM command is used to set the limits for the
comparison.
