Changed Functionality on Different
Firmware Releases
Changes in Version 1.6
Digital Input 1 has to be activated in order to transmit
periodical SMS.
The EasyTrack has to be continuously powered. This avoids a
GPS "Cold Start" with every trip that you start.
Easy Track will require a few minutes to connect with the GPS
signal.
Note:
EasyTrack will draw about 90mA (@12V) current from
your vehicle's battery while it is continuously powered.
Changes in Version 1.7
The EasyTrack will
check the level of cellular radio
strength intensity
before it will send SMS data.
This firmware change avoids trip data lost in the case where
coverage is below 10%.
The next successful SMS transfer will include all the
summarized information from the previous messages not sent.
Changes in Version 2.0
An update to this firmware release is obligatory for EasyTrack,
thus 1.6 and 1.7 may produce GSM errors after EasyTrack
has started up.
Additionally, included in this firmware is the
use of "GPS-
Speed"
instead of wheel pulses. If you configure your
EasyTrack "pulse per meter" value to 0 (zero), the EasyTrack
will calculate and transfer trip data based on the speed
information that is provided by the GPS receiver (dependant
on the availability of the GPS signal).
Changes in Version 2.3
GSM module will be forced to search for a network if it fails to do by
itself (targets a bug in the GSM module, that occurs rarely after 2
weeks of continuous operation)
Changes in Version 2.4
The GPS module will be restarted if it fails to send data (issue in winter
with old type of GPS modules)
Changes in Version 2.5
The values for MAX-Speed and MIN-Speed are smooth filtered so
wrong values (i.e. double speed) are avoided
Changes in Version 2.6
Fixed a bug where it could happen, that after switching off the vehicle
in a place where no GSM was available, the unit forgot to send a
message with the next ignition ON
