Performed by: Rea Yeheskel Yair Sommer Instructor: Idan Katz Cooperated with:Motorola הטכניון - מכון טכנולוגי לישראל הפקולטה להנדסת חשמל Technion - Israel institute of technology department of Electrical Engineering Initial project characterization SW application for Motorola g20 cellular engine 15 APR 2004 1 המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory

2. Background: Abstract המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 2 - Each operation requires an Input using AT commands. - During the integration process, customers need to spend time for accessing and using the cellular engine interfaces. Repeating a sequence of AT commands is exhausting (on the first stage of testing). - g20 cellular engine supports various operations. (sms, data transmission, voice, stk, etc.) - There is a need to reduce the “ Time to market ”.

3. Abstract המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 2 Project Goal: Writing a SW API Layer, with a GUI application for the g20 cellular engine. (The SW API will be a customer reference for the way code should be written during the development of their applications.)

4. System description המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 3 AT commands over RS232 SIM GUI lower level “interperter” to AT commands AT commands over RS232

5. System description המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 3 1.Creation of a low level API SW layer for the g20 cellular engine. The component will interact with g20 over RS232 from one side and with the SW application on the other side. 2.Creation of a high level application GUI that interacts with the API ’ s and graphically operates the g20 functionalities (using the lower level API modules). The Project has two parts:

6. Specification המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory Software – phase I - A SW API will be written for every basic group of operations. 4 Protocol layer (AT commands) SMS API Phone API GPRS API TCP/UDP API STK API More g20 API GUI Application Tests Module GUI Application - A Tests module will be written, providing the customer the ability to write scripts of AT commands.

7. Specification המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory sms API - send & receive short messages from memory or keypad - define Unicode, ASCII, etc. 4 phone API - initiate & receive voice calls, dial from memory or keypad - call management – call waiting, conference calls, etc. Tests Module - Enable the customer to write scripts of AT commands, useful to perform quick and easy tests.

8. Time Table המעבדה למערכות ספרתיות מהירות High speed digital systems laboratory 5 15 APR 2004 - Initial project characterization Presentation. 22 APR 2004 – Define final API modules to implement. 29 APR 2004 - Acquire knowledge for operating AT commands and getting signals through SW. 2 MAY 2004 – Define final implementation and algorithms. 10 MAY 2004 – Status Report for Part I – Instructor 18 MAY 2004 – Status Report for Part I – Teaching staff
