Connect TCP and Send GET Requests

This example tests the DFRobot_SIM808 GPS/GPRS/GSM Shield's ability to connect TCP and send GET requests

1. Open the `SIM808_TCPConnection` example or copy the code to your project

2. Download and set the function switch to `Arduino`

3. Open the serial terminal

4. Wait for until `Connect mbed.org success` is printed in the terminal

5. The serial terminal will print `Hello world!`
