Dev Tips and Sample Code

This tutorial explains how to send an SMS from your Raspberry Pi without using a GSM modem. In this tutorial, we'll be sending the SMS through the internet using the ClickSend SMS API.

  1. Create an account at ClickSend.com

  2. Create a Python script and add your ClickSend credentials

csharp
# - * -coding: utf - 8 - * -username = 'User'
# Your ClickSend username api_key = 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX'
# Your Secure Unique API key msg_to = '+61411111111'
# Recipient Mobile Number in international format(+61411111111 test number).msg_from = ''
# Custom sender ID(leave blank to accept replies).msg_body = 'This is a test message'
# The message to be sent.import json, subprocess request = {
  "messages": [{
    "source": "rpi",
    "from": msg_from,
    "to": msg_to,
    "body": msg_body
  }]
}
request = json.dumps(request) cmd = "curl https://rest.clicksend.com/v3/sms/send -u " + username + ":" + api_key + " -H \"Content-Type: application/json\" -X POST --data-raw '" + request + "'"
p = subprocess.Popen(cmd, stdout = subprocess.PIPE, stderr = subprocess.PIPE, shell = True)(output, err) = p.communicate() print output

  1. Connect to the Raspberry Pi via SSH/PuTTY (Raspberry pi must be connected to the Internet) https://raspberrypi4dummies.wordpress.com/2013/03/17/connect-to-the-raspberry-pi-via-ssh-putty/

  2. Copy script clicksend.py from your windows PC to your Raspberry Pi. (../home/pi)

  3. Start script clicksend.py with your parameters: python clicksend.py

  4. Done! Your SMS should've been sent by now.
