4.14.2.1
Antenna failure unsolicited response
This unsolicited response is sent when there is a failure in any of the antennas. The unsolicited response is
always on and cannot be turned off with the AT*EUNSOL command. Format:
*EUNSOL: FAILURE,ANTENNA <failure_status>
Parameter
<failure_status>

4.14.3
AT*EANTDIAG (Antenna Diagnostic command)
Description
Reads antenna status
Reads antenna value
This command polls for the antenna status of both antennas, if available. If the module is configured for only
one antenna then the second parameter is not returned. The first value returned is always the current antenna
and the second value is the other antenna (see AT*EASW for antenna switching details).
The return <value> is the actual ADC reading of the antenna diagnostic voltage divider network. Based on the
ADC reading, the current antenna <status> can be returned as GOOD, OPEN, or SHORTED. The <status>
that is returned is determined by the limits that are set by the AT*EANTLIM command.
Notes:
•
A centered ADC return value of 127 indicates a properly connected antenna with a resistance to
ground of 10K ohm. Resistance changes of 5% or less per ADC LSB are maintained for the
antenna resistance range of 1K ohm to 20K ohm.
•
An unsolicited message is returned on any status change for only the current selected antenna.
