ආර්ඩුයිනෝ වැඩ්ඩො ඉන්නවද?
මෙන්න මේ කෝඩ් එකේ තියෙන අවුල මොකද්ද කියහන්කො බන්.

Code:
/*
### Connect TCP and send GET request.
1. This example is used to test DFRobot_SIM808 GPS/GPRS/GSM Shield's connect TCP and send GET request.
2. Open the SIM808_TCPConnection example or copy these code to your project
3. Download and dial the function switch to Arduino
4. Open serial helper
5. Waiting for a few minutes, until serial has sent "Connect mbed.org success"
6. Serial will send "Hello world!"
