Description
All the criteria for the configured Communication Mode were satisfied.
This is the normal code used when there are no problems in original
message transmission. For GPRS, the UDP/TCP connection was
established and, if the TrimTrac Session Protocol is enabled, the session
sign-on message was sent and acknowledged.
No attempt was made to transmit the message. The Report Delay Flag
was set to "1=Exception Reports-only".
TrimTrac ProE was not able to acquire a usable network. This is
typically inadequate GSM coverage. If TrimTrac ProE is configured
for GPRS, then this code will also occur if there's a SIM configuration
mismatch (i.e., SIM is configured SMS-only). If TrimTrac ProE is
configured for SMS, this code will occur if SMS transmit fails (happens
occasionally) and the number of transmit attempts is exhausted. Note,
if the server application receives a message from the TrimTrac ProE
that has the GSM Status Code set to "2=Network Timeout", then the
message was transmitted after the fact due to the Automatic Message
Log Dump feature being enabled.
No SIM present or SIM not accessible. This is usually "no SIM
present" or "SIM not properly seated in carrier". This could also be a
bad SIM or SIM locked due to more than 3 attempts to access with
invalid PIN code (In this case a PUK code from the network provider is
needed to unlock the SIM.)
SIM requires a PIN and the correct PIN was not provided. TrimTrac
ProE keeps track of the number of times a PIN is rejected to prevent the
SIM from becoming locked (more than 3 attempts will lock the SIM).
The message was logged but a failure occurred that prevented
transmission. This is the initial logged status prior to transmission
attempt; it will be updated with Network Available or one of the error
codes as communications progresses. This code should not occur
unless TrimTrac ProE power is removed during the transmit process.
Initialization of TrimTrac ProE's GSM module did not complete
correctly. This code is an indication of an internal error associated with
the GSM module. It will occur when the batteries are too low to
support proper GSM module functionality.
Communication Mode is set "1=GPRS" or "2=AutoSelect" and the
device is registered with a network on which GPRS service is available,
but the device could not open a PPP session. This failure will occur,
for instance, if the TrimTrac ProE's GPRS communication parameters
are not properly set for the GPRS network provider as defined by the
SIM. The GPRS APN, GPRS Username, and GPRS Password must all
match that required by the GPRS network provider. This status will be
