7. Monitoring Module
To monitor module you will need terminal (can be downloaded from TrakGPS website:
http://www.trakgps.com/downloads/fm3101/terminal.zip). Plug the same cable, which was used
to configure module, to the Port 3 and launch terminal. Choose the COM port, that you are using
and click "Connect". To start logging session click "Start Log". Monitoring is usually used for
keeping track of modules behavior and possible errors.
7.1 Reading Terminal
When connecting power supply to the device, first line that it responds with is
"1980.1.1 0:0:10 223940028 176056 3Start".First symbols are timestamp for event. Default starting
time is 1980.1.1 0:0:0. When clock is set, the displayed time is in GMT format. 223940028 is thread
ID, 176056 –free RAM memory, 3 –log level. These are not essential to reading device's behavior,
so further messages will be displayed without them.
Next line that should be noticed is "Creating preference /boot".This means, that IMlet is
starting. If you don't see this line, start IMlet using configurator (chapter 5).
After skipping some lines you should see "Reading available operators..." followed by few lines
of "Checked [Name=OMNITEL LT][Area=24601]
[Priority=OPERATOR_PRIORITY_HOME_NETWORK][Status=OPERATOR_STATUS_CURRENT],
selected [Name=OMNITEL LT][Area=24601] [Priority= OPERATOR PRIORITY HOME NETWORK]
[Status=OPERATOR_STATUS_CURRENT] profile 1".
A list of available GSM operators is displayed here. Depending on country and available operators,
some parameters may vary. If no operators are visible or you are sure that there should be more,
check GSM antenna connection.
After some more lines "Operator selected [Name=OMNITEL
LT][Area=24601][Priority=OPERATOR_PRIORITY_HOME_NETWORK][Status=OP
ERATOR_STATUS_CURRENT], signal quality -70. GsmOperatorManager [Active profile=1] [Scan
interval=300000] [Online=false]" is displayed. This indicates which operator is chosen.
You should also see a line saying "Clock initialized 2007.5.3 7:12:21". This means, that
internal clock has been started and from now timestamp will use GMT time. This is a good way to
determine if GPS satellites are visible, because time is set using them. If clock is not initialized,
device shows exception: "Get parameter Time com.nokia.m2m.orb.idl.
