Figure 37 FM6320 profile structure
Switching between profiles (changing behaviour) can be performed by Profile switch
depending on GSM operator code (mostly used for roaming applications), or by Profile switch
depending on I/O event (on I/O value changing).
Profile 3 is default profile for FM6320. It is always loaded on the very first
start-up and further profile switching is proceeded after operator scan or I/O
element changes (although device remembers which profile it used after
that).
7.1
Profile Switching dependence on GSM Operator
GSM Operator code profile switching is mostly used in roaming applications, when the
purpose is to have information from module both from Home and Roaming operator network for
a reasonable price. This method allows you to define different module behaviour in Home
network, Roaming network and unknown operator areas. See figure below for details.
Profile 1 is configured for home network. Data acquisition and send intervals are quite
frequent here. To make profile use effective, it is wise to set more optimized parameters in
roaming profile (Profile 2) – this usually includes larger coordinate recording intervals, packets
with greater number of coordinates sending, and in some cases GPRS context available only for a
certain time interval. Profile 3 can either contain operator codes (rarely used) or have an empty
list. Profile 4 is not used (profile 4 can only be used when FM6320 encounters a 'panic' priority
event (see 7.2 chapter)).
In the example (Figure 38) FM6320 connects to operator with code 24702. It checks profile
1 operator list, but there is only one operator code entered which does not mach. Then it checks
profile 2 operators list. This code is entered there, so FM6320 switches to profile 2.
If there are no operator codes entered in all profiles after operator search task FM6320 will
check all 3 profiles and won’t find any operators in any list. In such a case, FM6320 will switch to
profile 3. Note that before switching to profile 3, the device closes the GPRS session.
