تست و نصب ساده

 ابتدا برنامه ذیل تصویر را به آردوینو یونو بارگزاری کنید .  سیم کارت را نصب کرده و از پایه 11 آردوینو یونو به پایه ترانسمیت بورد و پایه 10 به پایه رسیو برد اتصال دهید از ولتاژ 5 ولت روی برد 5 ولت آردینو و از زمین آردینو به زمین برد متصل کنید سپس برد آردوینو را به کامپیوتر متصل کنید و کلید روشن شدن برد  روی ماژول A6 را به مدت حداقل 7 ثانیه فشار دهید تا ماژول روشن شود. .کام پورت نرم افزار آردوینو را در سرعت و باد ریت 115200 تنظیم و باز کنید تا مراحل اتصال به شبکه در خروجی سریال آردوینو مشاهده شود. بعد از اینکه اتصال شبکه با متن SERVICE = 1  در خروجی سریال آردوینو ظاهر شد آنگاه یک بار آردوینو را ریست کنید تا پیامک به شماره مورد نظر فرستاده شود و پیام OK  نیز دریافت شود. با فشار دادن کلید OFF  روی ماژول A6  این ماژول خاموش میشود. اگر شبکه شناسایی نشد یکبار دیگر ماژول A6  را خاموش و روشن کنید تا علامت SERVICE=1  در خروجی سریال دیده شود.

Introduction

This is a A6 GPRS/GSM Shield, which is use the newest A6 GSM/GPRS module , A6 module is a GSM/GPRS function module.It supports GSM/GPRS Quad-Band（850、9001800/1900） network. Also, it supports voice calls,SMS messages,GPRS data service and so on .We can use it make a simple phone.
The module is controlled by AT command via UART and supports 3.3V and 4.2V logical level.

Interface Function

Usage

Hardware installation

Insert an Micro SIM card to SIM Card Holder

6 Pin Holder for SIM Cards. Both 1.8 volts and 3.0 volts SIM Cards are supported by A6 GPRS/GSM Module, the SIM card voltage type is automatically detected.

Connect the Antenna

A miniature coaxial RF connector is present on the Crowtail- A6 GPRS/GSM Module to connect with a GSM Antenna. The connector present on the Crowtail- A6 GPRS/GSM Module is called a U.FL connecto.The GSM Antenna supplied with the GPRS Shield has an SMA connector (and not an RP-SMA connector) on it.The connection topology is shown in the diagram below:

Plug to Arduino/Crowduino

Connect the Crowtail- A6 GPRS/GSM Module to U1 port on Crowtail- Base shield,and then plug the base shield onto Arduino

Download Code

1. Type command in the terminal to execute different function, threr are 4 functions in the demo:
   1. If you input ‘t’, the demo will send a SMS message to another cellphone which you set(you need set the number in the code);
   2. If you input ‘d’, the program will dial a call to the other cellphone that you set(it is also need you set in the code );
   3. If you input ‘h’, it will submit a http request to a web that you want to access(it need you set the web adress in the code), it will return a string from the website if it goes correctly;
   4. If you input ‘s’, it will upload the datas to the pachube(for detail you can refer to the explanation in the code). I strongly recommend you input ‘h’ before input ‘s’, because uploading datas to the pachube need do some setting, after execute the function of submit a http request, the setting will be set.
2. If the program returns error in the terminal after you typed the command, don’t worry, just try input the command again.
