Step 3:
Type ‘
reboot

mode again to check the firmware version. If it is correct, then the firmware
update is complete.

Update firmware over the air (OTA) by GPRS
1. ORION OBDtrac supports over the air upgrade after firmware version
970708. Also the firmware replies each SMS protocol command to
sender’s phone number. It becomes much easier for the tracker
maintenance.
2. ORION releases the .img file (Application code only) to allow our
customers to update the firmware over the air by GPRS. The system
administrator uploads the .img file to a web server, then sends a
protocol command to the tracker by SMS or GPRS. Afterward the
tracker will perform the firmware download and update by itself.
3. It takes only 3 steps to update the firmware over the air by GPRS.
Please follow the instructions below to update the firmware of the
tracker.
Step 1:
Put the new firmware on a web server and come out the URL.
(Ex.
http://211.79.38.93/970709.img
or
http://211.79.38.93:8080/970709.img
).
Or
you may use the URL provided by ORION. Please note that you may have
to rename the .img to .zip or other file name in order to pass the firewall.
(Ex.
http://211.79.38.93/970709.zip
). Note that only http is supported, not
ftp.
Step 2:
Send the protocol command
$ActUpgradeFW,
[Command
S/N],[Password],[URL]&
by SMS or GPRS to the tracker to initiate the
firmware update process.
Step 3:
Verify if the firmware update is successful by its return message.
Here are 4 cases of return messages.
1. When the tracker receives the command without problem, it will reply
the following acknowledgement first.
$ActUpgradeFW,[Command S/N],OK,[RTC Time]&
2. If the firmware download is in progress or parameters error, it replies:
$ActUpgradeFW,[Command S/N],Param,[RTC Time]&
