    Wiring

    1. AT communication


    2. Uploading firmware


    Step by Step instruction

    1. Configuring the A9G development board with USB to TTL converter


      For using this USB to UART Converter you need a software tool. Most of the development tools like MikroC Pro, Arduino has a UART Tool along with it. You can use different software tools: TerminalUSR-TCP232-Test V1.4AiThinker_Serial_Tool_V1.2.3cooltermsscom3.2KiTTYputty,tera termAccess port and so on. We recommend you to use AiThinker_Serial_Tool_V1.2.3 or sscom3.2, as you can save your AT commands and it's very easy to use.

      1. Do wiring.
      2. Attach GSM/GPRS antenna to A9G GPS GPRS development board.
      3. Attach GPS antenna to A9G GPS GPRS development board.
      4. Insert a valid unlocked Micro SIM card to SIM card slot of A9 GPS GPRS development board.
      5. Insert the Micro CD card to Micro SD card slot.
      6. Plug your USB to TTL converter into your PC USB port.
      7. You can power up A9G GPS GPRS development board Lithium-Ion battery V_BAT (3.5-4.2VDC) or use a power supply from USB to TTL converter. 
      8. Press the PWR button for 2 seconds. Status indication (blue LED) will be ON.
