Configure Antenna Diagnostics Polling Interval
+WANTPOLL
Description:
Syntax:
Values:
Multi-Tech Systems, Inc. CDMA C1 AT Commands Reference Guide (PN S000478C)
Values:
This command is used to configure the interval between primary and/or secondary antenna
diagnostic checks. When the antenna status changes, the modem outputs a +WANTS message.
A change of status is defined as an antenna ADC reading which crosses into a different range
(OPEN/NORMAL/SHORT) as defined by the short and open limit settings using AT+WANTLIM
for the antenna. The modem may also be configured to generate a ring indication when the
antenna diagnostic status changes.
If periodic diagnostic checking of the antennas is not desired, the application can query the
antenna status by using the AT+WANTS command.
The antenna status check occurs every <interval> seconds. One unsolicited message is issued
on any status change for the requested antennas.
