var myo = require('./myo.js');

CONNECT

Quick Connect

myo.quickConnect(function(err, id){
    console.log('myo unique id : ', id);
});

Classic Connect

myo.scan.start(function(err, data){
    console.log(err, data);
});
myo.event.on('ready', function(id){
    console.log('myo unique id : ', id);
});

DISCONNECT

myo.connected[id]..disconnect();

INITIATE

Initiate Myo to receive stream and data

myo.connected[id].unlock("hold", function() {
    // lock - time (will lock after inactivity) - hold
    myo.connected[id].sleepMode("forever", function () {
        // normal - forever (never sleep)
        myo.connected[id].setMode('send', 'all', 'enabled', function () {
            // emg : none - send - raw
            // imu : none - data - events - all - raw
            // classifier : enabled - disabled
            console.log('initiated');
        });
    });
});    

INTERACTION

Get Name

myo.connected[id].generic.getName(function (err, data){ // Get device name
    console.log(err, data);
