  • DroidScript now lets you program Espruinos from your mobile phone
    in News •
    Avatar for Dave_Smart

    Hi Guys,

    I thought that you might be interested to know that the latest beta version of DroidScript now lets you target Espruino as a project type.

    This allows programming of Espruino micro-controller boards directly from your Android Phone/Tablet using an OTG cable. It works completely off-line (even with Espruino modules), so you can use DroidScript as an in-the-field programming device even when you have no mobile signal. A USB serial terminal will popup when you run this type of project and allow debugging and testing etc too :)

    This version of DroidScript is currently in beta and the APK can be directly downloaded here:-
    http://androidscript.org/beta/DroidScript_157b1

    (If you join the beta program then it will be available to you through Google Play too)

    I would be grateful for feedback on the current functionality before I do a public release. If you would like to join the DroidScript beta forum, then please send a request to david@droidscript.org

    Thanks
    David

  • NFC payment

    You could probably combine NFC and BLE to do it. I've already implemented BLE payments with DroidScript and Paypal on an Android tablet acting as a BLE server/advertiser... but I used a Puck as my test server before I got hold of the tablet. You might be able to trigger off the BLE comms process using the NFC and then authorise a payment using PayPal or Stripe after some handshaking over BLE

    Just use this code on DroidScript (make sure you install the Puck.js plugin on DroidScript first)

    app.LoadPlugin( "PuckJS" );

function OnStart()
{
  lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
  txt = app.CreateText( "Press your puck" );
  lay.AddChild( txt );
  app.AddLayout( lay );
  puck = app.CreatePuckJS();
  puck.SetOnConnect( OnConnect );
  puck.SetOnButton( OnButton );
  puck.Scan( "Puck" );
}
function OnConnect()
{
  puck.WatchButton( true );
}
function OnButton( state )
{
  txt.SetText( "Hello World" );
}

  • Best way to send Javscript code with own Android app.

    Actually the easiest way is to use free coding tool DroidScript with the free Puck.js plugin.
    Here is the code (taken from the Puck.js plugin docs)

    app.LoadPlugin( "PuckJS" );

function OnStart()
{
  lay = app.CreateLayout( "Linear", "VCenter,FillXY" );

  var code = "digitalWrite( LED1, 1 )"; 

  txt = app.CreateTextEdit( code, 0.9, 0.8, "MultiLine" );
  lay.AddChild( txt );
  app.AddLayout( lay );

  layHoriz = app.CreateLayout( "Linear", "Horizontal" );
  lay.AddChild( layHoriz );

  btnSend = app.CreateButton( "Send", 0.3, 0.1 );
  btnSend.SetOnTouch( btnSend_OnTouch );
  layHoriz.AddChild( btnSend );

  btnSave = app.CreateButton( "Save", 0.3, 0.1 );
  btnSave.SetOnTouch( btnSave_OnTouch );
  layHoriz.AddChild( btnSave );

  btnReset = app.CreateButton( "Reset", 0.3, 0.1 );
  btnReset.SetOnTouch( btnReset_OnTouch );
  layHoriz.AddChild( btnReset );

  microbit = app.CreatePuckJS();
  microbit.Scan( "Puck" );
}

function btnSend_OnTouch()
{
  microbit.SendCode( txt.GetText() );
}

function btnSave_OnTouch()
{
  microbit.Save();
}

function btnReset_OnTouch()
{
  microbit.Reset();
}

    Here is a more sophisticated solution that does not require a constant (battery draining) connection:-

  • Puck button integration with android device.

    Avatar for Dave_Smart

    Hi Guys, You can easily do this in DroidScript with the BLE plugin

    Here is the Puck.js code:-

    function advertise(url) {
  var d = [0x03, 0x03, 0xAA, 0xFE, 0x13, 0x16,  0xAA, 0xFE, 0x10,  0xF8, 0x03 ];
  d.push.apply(d,url.toString().split(""));
  d[4] = d.length-5;
  NRF.setAdvertising(d, {interval:100});
}

advertise( "call.false");

function makeCall( call ) {
    advertise( "call."+call  );
    digitalWrite( LED3, call?1:0 );
}

setWatch(function() {
   makeCall( true );
   setTimeout( function() { makeCall(false) }, 5000 );
}, BTN, {edge:"rising", debounce:50, repeat:true});

    And Here is the DroidScript code:-

    app.LoadPlugin( "BluetoothLE" );

function OnStart()
{
  //Create a text control to show debug log.
  lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
  txt = app.CreateText( "", 1, 1, "Log" );
  lay.AddChild( txt );
  app.AddLayout( lay );

  //Create Bluetooth LE object.
  ble = app.CreateBluetoothLE();
  ble.SetOnDevice( OnDevice );
  
  //Check for Puck button presses every 3 seconds
  setInterval( CheckForButtonPress, 3000 );
  txt.Log( "ready" );
  calling = false;
}

function CheckForButtonPress()
{
    //Do a brief scan to check for puck button press.
    ble.StartScan();
    setTimeout( function(){ble.StopScan()}, 1000 );
}

//Called when any BLE device is found by the scan.
function OnDevice( name, address, bonded, rssi, data )
{
  txt.Log( name + ": " + data.url );
  if( data.url=="https://call.true" ) MakeCall();
}

//Make the call (limit to one every 5 seconds).
function MakeCall()
{
    if( calling ) return;
    txt.Log( "calling", "red" );
    
    calling = true;
    app.Call( "01359555222" );
    setTimeout( function(){calling=false;}, 5000 )
}

    You could optionally put the DroidScript code inside a DroidScript service and have it always running in the background on your phone too :)

  • Connection Timeout while connecting to GATT Service on Android Device
    in Puck.js, Pixl.js and MDBT42 •
    Avatar for Dave_Smart

    FYI: The ASUS ZenPad Z380M works as a GATT Server. The best app to test BLE server capability is the Nordics "nRF Connect" app on Google Play. You need devices with Android 5 or higher and hardware support included.

    Worth mentioning that DroidScript has a BLE Beacon/Server plugin in beta (if you ask on the forum then you can probably get hold of it)

    You could also build a DroidScript service which stays always running in the background and watches for the button presses.

    OK, I was wrong. It took 2 minutes :)

    Here is the code:-

    app.LoadPlugin( "PuckJS" );

function OnStart()
{
  lay = app.CreateLayout( "Linear", "VCenter,FillXY" );
  txt = app.CreateText( "Press your puck" );
  lay.AddChild( txt );
  app.AddLayout( lay );

  puck = app.CreatePuckJS();
  puck.SetOnConnect( OnConnect );
  puck.SetOnButton( OnButton );
  puck.Scan( "Puck" );
}

function OnConnect()
{
  puck.WatchButton( true );
}

function OnButton( state )
{
  app.Call( "01359555555" );
}
