only the Maintenance socket is ready. A ‘.’ indicates no sockets are ready.
o [./a/A]:
This field indicates if the LMU has received an Acknowledgement from the Inbound
server. This field will be empty if the LMU has never received an ACK. The lower case
‘a’ will be present if it has received an ACK since the last cold boot (i.e. power cycle) but
not the last warm boot (App Restart or Sleep). The upper case ‘A’ will be present if the
LMU has received an ACK since the last warm boot. A ‘.’ Indicates no
acknowledgement has been received.
o [./L]:
This field indicates if the LMU’s log is currently active. An ‘L’ indicates that the log is
currently in use (i.e. one or more records have been stored) where a ‘.’ indicates the log is
inactive.
o [IP Address]:
This is an optional field if and is only present if the LMU has established a valid data
session. This field will contain the current IP address of the LMU as assigned by the
wireless network. Note that if you see a value of 192.168.0.0, this is an indication that the
LMU has not been able to establish a data session.
o [<APN>]
The current Access Point Name in use by a GSM LMU.
GPS:
o [Antenna <Short/Open/Off>]:
This field, if present, indicates a problem with the LMU’s GPS antenna. A value of Short
indicates that the antenna cable has likely been crushed. A value of Open indicates that the
antenna cable is either cut or disconnected. A value of Off indicates that the LMU’ GPS
receiver is off.
o [No Time Sync]:
If this field is present, it indicates that the LMU’s GPS receiver has not been able to find
even a single GPS satellite. This would likely been seen in conjunction with the above
antenna error, or if the LMU GPS antenna is otherwise blocked.
o [<FixStatus> <Sat Count>]:
If these fields are present it indicates that the LMU has, or had a valid GPS solution. The
<Sat Count> field indicates how many GPS satellites are currently in use by the LMU.
The <FixStatus> field indicates the type of fix. The Fix Status types are detailed in the LM
Direct Reference Guide.
