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 ”.

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.)

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:

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.

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.
