Experiment # 7
  • E7.1 Name:


    • ARM Cortex M0 - Communications in GSM networks


  • E7.2 Overview / Purpose:


    • The laboratory experiment aims to offer an option to develop an active core able to communicate in GSM networks for M2M applications. At the end of the lab, detailed information will be provided on the use of GSM modems and AT commands to develop capabilities to manage SMS in mobile networks.


  • E7.3 Resources:


    • Platforms XMC100 boot kit, Reverse Dial
    Communications Cable,
    GSM GSM / GPRS GSM Modem,
    Terminal Terminal Emulator for WINDOWS -TeraTerm.

  • E7.4 Prototype Source:


    • Prototype program

  • E7.5 Experiment Run / Tracking Mode:

    • - Connect the GSM modem to PC-Com1 / 2. Using the TeraTerm terminal program tests the AT commands for sending SMS;

    -


    Examine the GSM extension scheme shown in the figure below: - Expose the AT commands for SMS;
    - Perform a project with the Protopic program and track the execution on the XMC 1100 Boot Kit platform;
    - Solving the proposed problems;

  • E7.6 Proposed Issues:

    • 1. Make a program sequence that will send SMS to 2 phone numbers;

    • 2. Make a program sequence that will send an SMS with the supply voltage value of the XMC 1100 processor;

    • 3. Make a program sequence that allows viewing of the AT commands sent to the modem on the terminal application;
    • 4. Emphasize the electromagnetic disturbances introduced by the modem's GSM modem;

    • 5. Make a program that will transmit AT commands to the GSM modem without using delay functions;

  • E7.7 The experiment can be extended to:

    • Carrying out telemetry applications with GSM;
    Making active nodes for the Internet of Things;
    Application development on M2M structures;
    Interconnection at very large equipment distances;
