2 Generating Applications With the Open AT
Wizard
2.1 Creating an Application With the Wizard
This Wizard provides a user-friendly way to create an Open AT project. It is
used to manage the following operations:
! Visual C++ project creation,
! Compilation, link and library settings.
The different steps in creating an Open AT project are listed in the following
paragraphs.
2.1.1 Step 1: Launching the Wizard
1) From the main Visual C++ screen, select “File”
“File”“File”
“File” -> “New…”
“New…”“New…”
“New…”,
2) In the “New”
“New”“New”
“New” window, select the “Projects”
“Projects”“Projects”
“Projects” tab,
3) From the list box, select “Wavecom
“Wavecom “Wavecom
“Wavecom Open AT
Open ATOpen AT

””
”,
4) In the “Location”
“Location”“Location”
“Location” text field, choose the path corresponding to the
location where the project is going to be created,
5) In the “Project Name
“Project Name“Project Name
“Project Name” text field,
, ,
, indicate a project name,
For this example, enter “
““
“Call Monitoring
Call MonitoringCall Monitoring
Call Monitoring” as the
project name.
Note:

Note: this name is added to the previously chosen path.
6) End the initialization using “OK

: The Open AT Wizard will insert template files into the project
(appli.c and appli.h) with the basic functions (see the minimum embedded

utils.h header), containing the string and memory manipulation functions, is
available. This is the default option.

when the user wants to create a new project using existing application
code files. These files will then have to be manually added to the project.
For this example, select the “Sample Project”

2.1.3 Step 3: Other Settings
The user has to define two parameters which are used in the Remote
Application environment:
! Stack Size:
Stack Size:Stack Size:
Stack Size:
this parameter is not used in the Remote Application
environment, but is written in appli.c. It defines the size of the target call
stack memory (see Stack Size in the Development Guide).
! Update Wavecom delivery files:
Update Wavecom delivery files:Update Wavecom delivery files:
Update Wavecom delivery files: this option enables the Open AT wizard to
re-install headers and library files needed in the Remote environment. It
creates a “V100”
“V100”“V100”
“V100” directory (if there is none) with updated files, at the same
level as the project directory.
For this example, check the “Update Wavecom
“Update Wavecom “Update Wavecom
“Update Wavecom
delivery files”
delivery files”delivery files”
delivery files” box.
Use the “Finish”
“Finish”“Finish”
“Finish” button to create this embedded application project. A
message box appears that summarizes the directory structure to be created.
Press “OK”
“OK”“OK”
“OK” to finish creating the project.
2.2 Directory Architecture
The typical directory tree structure of the application generated by the Open AT
wizard is shown below :
Figure 2 : Directory Structure
The “Root”
“Root”“Root”
“Root” directory is the directory entered in the “Location”
“Location”“Location”
“Location” text field in the
Open AT wizard step 1.
The “Call Monitoring”
“Call Monitoring”“Call Monitoring”
“Call Monitoring” directory is specific to the new application (this was the
text entered in the “Project Name”
“Project Name”“Project Name”
“Project Name” text field in the Open AT wizard step 1).
It is made up of the following sub-directories :
! Debug
DebugDebug
Debug: contains the Remote Application binary, which will be generated by
a “Build”

“NO SIM” string will be
displayed if no SIM is inserted; otherwise the
“ENTER PIN CODE”

3 Generating an Application without the Open
AT Wizard
3.1 Directory Architecture
In the directory of your choice, create a new directory using the name of the
application. In this directory, create two directories named “src”
“src”“src”
“src” and “inc”
“inc”“inc”
“inc”.
The “src”
“src”“src”
“src” directory will contain all the user’s source files.
The “inc”
“inc”“inc”
“inc” directory will contain all the user’s header files.
The first call to the Wavecom “c”
“c”“c”
“c” tool will create a “target”
“target”“target”
“target” directory, at the
same level as the “src”
“src”“src”
“src” directory. This “target”
“target”“target”
“target” directory will contain the files
generated by Wavecom tools, including the embedded application binary.
For this example, copy the “Call Monitoring”
“Call Monitoring”“Call Monitoring”
“Call Monitoring”
directory from the CD-ROM directory
“Samples
“Samples“Samples
“Samples\
\\
\Call Monitoring”
Call Monitoring”Call Monitoring”
Call Monitoring”, and remove all “read
only” files attribute.
3.2 Creating Embedded Applications
3.2.1 Coding the Application
See the Development Guide
Development GuideDevelopment Guide
Development Guide and the AT Commands Interface
AT Commands Interface AT Commands Interface
AT Commands Interface to create the
embedded application. One of the source files (for example “appli.c”
“appli.c”“appli.c”
“appli.c”) must
contain the minimum required code (See Minimum embedded application code
in the Development Guide). Do not forget to copy all the user source files in the
“src”
“src”“src”
“src” directory, and the header files in the “inc”
“inc”“inc”
“inc” directory.
For this example, a full Call Monitoring system
has been implemented. Refer to the source files,
and to a readme.txt file from the CD-ROM
directory “Samples
“Samples“Samples
“Samples\
\\
\Call Monitoring
Call MonitoringCall Monitoring
Call Monitoring.”
””

3.2.2 Application binary generation
• In a MS-DOS command window, call the “WmMake xxx”
“WmMake xxx”“WmMake xxx”
“WmMake xxx” command in
the root directory, where “xxx”
“xxx”“xxx”
“xxx” is the makefile name.
For this example, call the “WmMake
“WmMake “WmMake
“WmMake
call_monitoring”
call_monitoring” call_monitoring”
call_monitoring” command from the “Call
“Call “Call
“Call
Monitoring”
Monitoring”Monitoring”

• Check in the created “target”
“target”“target”

“.obj”“.obj”
“.obj” compiled files.
In the “src”
“src”“src”
“src” directory, the “.lst”

This file is the Embedded Application binary, ready to be downloaded to
the target.
3.3 Download
In order to download the “.dwl”
“.dwl” “.dwl”
“.dwl” file to the target, follow these steps:
1. Launch HyperTerminal;
2. Configure it to open the COM port (see figures 3, 4 and 5);
