Presentation Transcript

  1. Open-AT presentationwww.sendsms.cn

  2. Overview • Software mechanism allowing a customer to embed an AT commands based application into a Wavecom product • Customer application to be developped in C language • Specific development and debug tools provided by Wavecom • Available on all Wavecom dual band products starting from Q1/01

  3. Embedded Application Wavecom Core Software Principle External application driving the Wavecom device through the serial link

  4. Software architecture Embedded software Embedded Core Wavecom library Embedded Application Embedded API Layer Application Mandatory API AT Cmd Embedded API OS API Standard API Wavecom Core Software Wavecom API Layer OS API AT Command API Wavecom Core WAVECOM MODULE

  5. Operating modes • The Open-AT facility supports several operating modes : • A stand alone mode: the embedded application drives the Wavecom device on its own • a « dual » mode : the embedded application co-operates with an external application • a standard mode in which the external application drives the Wavecom device (no interaction with the embedded application)

  6. Embedded Application Wavecom Core Stand-alone mode • The embedded application drives the Wavecom Core software through an internal mechanism based on send and receive AT commands primitives

  7. Embedded Application Wavecom Core External Application Cooperative mode (1) • The embedded application can be used to cooperate with an external application

  8. Cooperative mode (2) • The embedded application can then filter: • The AT commands sent by the external application to the Wavecom core (pre-parsing) • The responses received from the Wavecom core (post-parsing) • The Open-AT facility also allows the embedded application to take control of the serial link • The data flow can then be fully application specific

  9. Technical overview • The following resources are available for the embedded application: Memory size •  512 kBytes ROM •  32 kBytes RAM Processing power •  0.5 MIPS during GSM communication • 1 to 2 MIPS when no GSM com. active

  10. Tools • In order to ease the development Wavecom provides debug tools running on PC: • Embedded application simulator • External execution environment for the embedded application • Terminal emulator • Traces monitoring software

  11. Primitives • The main API primitives available are: • AT commands related API • Send AT command • Subscribe to unsollicited indications,… • OS related API • Start/Stop timer • Read/Write data in Flash memory • Init/Get/Release memory,…
