  • I was wondering where can I get the wifi module. Also does Esprunio have a 3G cellular module.

  • I am using the GSM2 Click with the espruino for GSM. There is an AT library (¬≠/blob/master/modules/AT.js) that has been utilised within the wifi modules and some of the others. I am using this library to send commands to my GSM module.

    Example code:

    var at = require("AT").connect(Serial4);
    function SendSMS(phone_num,message,callback){
        console.log('Phone number set:' + phone_num);
          console.log('Message text set:' +message);
            return callback('Message sent');
