This package uses a serialport to communicate with the SIM900 GSM Modem.

• You'll need Golang v1.3+
• SIM900 Package uses the serial package in order to communicate with the modem via AT commands, you will need to install both SIM900 and serial packages.

go get github.com/argandas/serial  # installs the serial package
go get github.com/argandas/sim900  # installs the SIM900 package

• You'll need an available serial port, SIM900 boards usually works with 5V TTL signals so you can get a USB-to-Serial TTL converter, I recommend you to use the FTDI Cable for this, but you can use any USB-to-Serial adapters there are plenty of them.

• Connect carefuly your serialport to your SIM900 board.

package main
import "github.com/argandas/sim900"

func main() {
	gsm := sim900.New()
	err := gsm.Setup("COM1", 9600)
	if err != nil {
		panic(err)
	}
	defer gsm.Teardown()
	phoneNumber := "XXXXXXXXXX" // The number to send the SMS
	gsm.SendSMS(phoneNumber, "Hello World!")
}

• List of available SIM900 commands can be found here.
