10 Firmware Upgrade Procedure

IMPORTANT NOTE: There have been different versions of the Wavecom GSM module used during
the production of the iCE

To match the internal operating system in these, iQuest provides multiple

iCE

firmware variants. The major version number defines the internal module used. Therefore it is

very important that the version be checked (using the AT^IVER command) prior to upgrading the
firmware. For example, if the AT^IVER command returned a version of 2.01, then the latest version
firmware V2.xx would be used.

Firmware upgrades are issued as a single file for downloading and flash upgrading via HyperTerminal®.
The file is available from the iQuest web site and is in the format:

iCE3_GPRS_V120.dwl

iCE3 GPRS Firmware, Version 1.30 (Major version 1)

In the upgrade example below, we are upgrading an earlier iCE

that has version V1.14 installed. The latest

firmware version for this particular model is V1.30.

NOTE: This procedure assumes familiarity with HyperTerminal®, the default serial terminal program that is
supplied with Windows®.

1) Connect to the iCE

with HyperTerminal. Settings should be 9600bps, no parity, eight data bits and

one stop bit. (9600 n 8 1).

2) Ensure the iCE

is in command mode by typing AT [Enter]. It should respond with OK. If there is no

response, take the iCE

off line by typing +++ quickly.

3) Type AT^IVER?[Enter] to display the device version. Check the version to determine if the iCE

actually requires an update.

4) If so, put the iCE

into programming mode by entering the command AT+WDWL[Enter]. It will start

transmitting a special prompt character at regular intervals.
