Puck as U2F/Fido2 Device

in Puck.js, Pixl.js and MDBT42 • 2 years, 11 months

Should it be possible to turn the Puck into an Fido2/U2F device?

I found this

and this

NRF.setServices Datatypes

in Puck.js, Pixl.js and MDBT42 • 6 years, 11 months

just an info how far i am. no help required.

i think the puck crashes. i have to attach a serial console.

Puck:

var IrData = [];

function setService(){
  NRF.setServices({
    0xBCDE : {
      
      0xFF01 : { /*clear buffer*/
        writable : true,
        onWrite : function(evt) {
          //digitalWrite([LED3,LED2,LED1], evt.data[0]);
          if (evt.data[0]==255){
            IrData = [];
            LED3.set();
            setTimeout(()=>{LED3.reset();},1000);
          }
        }
      },
      0xFF02 : { /*fill buffer*/
        writable : true,
        onWrite : function(evt) {
          var array1 = new Uint8Array(evt.data);
          array1.map(val=>{
            IrData.push(val/10);
          });
        }
      },
      0xFF03 : { /*exec buffer*/
        writable : true,
        onWrite : function(evt) {
          if (evt.data[0]==255){
            LED2.set();
            setTimeout(()=>{LED2.reset();},1000);
          }
          //Puck.IR(IrData);
        }
      },
      0xFF04 : { /*reserved*/
        writable : true,
        onWrite : function(evt) {
          console.log( new Uint8Array(evt.data));
        }
      }
    }
  });
}

setService();

function advertise()
{
  var voltage = Math.round( NRF.getBattery() * 1000)/1000 ;
  voltage = voltage.toString();

  var data = {
    0x180F : [Puck.getBatteryPercentage()],
    0x1801 : [ voltage.split('') ],

  };

  var options = {

advertise();

NRF.setServices Datatypes

Hi,

i try to send some IR Codes via nodered + mqtt + puck to turn on my soundbar on chromecast activity.

msg.payload =  [ 8.9111328125, 4.5166015625, 0.48828125, 0.6103515625, 0.48828125, 1.77001953125, 0.48828125, 0.6103515625, 0.48828125, 1.77001953125, 0.48828125, 1.77001953125, 0.45776367187, 1.77001953125, 0.48828125, 0.6103515625, 0.48828125, 1.77001953125, 0.45776367187, 0.64086914062, 0.48828125, 0.64086914062, 0.48828125, 0.6103515625, 0.48828125, 0.64086914062, 0.48828125, 0.64086914062, 0.48828125, 1.73950195312, 0.48828125, 0.64086914062, 0.48828125, 1.73950195312, 0.48828125, 0.64086914062, 0.48828125, 0.6103515625, 0.48828125, 1.77001953125, 0.48828125, 1.77001953125, 0.45776367187, 0.64086914062, 0.48828125, 0.6103515625, 0.48828125, 1.77001953125, 0.48828125, 0.6103515625, 0.54931640625, 1.708984375, 0.48828125, 1.77001953125, 0.45776367187, 0.64086914062, 0.48828125, 0.6103515625, 0.48828125 ];

If i send the hole command as a string to /ble/write/e9:05:8c:a7:64:ab/nus/nus_tx it works.

So i'm questioning what are the limitations for self defined Services?
Can i send the IR Codes that way?

How "looks" the evt.data Object of the onWrite function?
How can one read that console.log as long as the puck is connected to the IDE?

onWrite : function(evt) { // optional
        console.log("Got ", evt.data);
      }

Thank you very much.

Puck js, how to send MQTT message with button pressed?

With both of them. I already increased the

to 2000 without success.

I will try this command later:

Do you know why that happends? Doesn't the code stop scanning before sending?

I cant send a write command to the puck:

I only found this information:
https://github.com/sandeepmistry/noble/issues/658

I had a look into the EspruinoHub code and i saw that the scanning is interruptet if a write message needs to be sent.

/* Write to the given device */
exports.write = function(device, service, characteristic, data) {
  if (isBusy) {
    queue.push(function() { exports.write(device,service,characteristic,data); });
    return;
  }
  isBusy = true;
  getConnectedDevice(device, function(err, connection) {
    if (err) return setNotBusy();

    connection.getCharacteristic(util.uuid2noble(service), 
                                 util.uuid2noble(characteristic),
     function(err,char) {
       if (err) return setNotBusy();;
       writeToCharacteristic(char, util.obj2buf(data), function() {
           log(connection.name+": Written.");
           setNotBusy();
         });
     });
  });
};

and

function serviceQueue() {
  if (!queue.length) {
    if (connections.length==0) // no open connections
      discovery.restartScan();
    return;
  }
  if (connections.length < MAX_CONNECTIONS) {
    var job = queue.shift();
    discovery.stopScan();
    setTimeout(job, 1000);  
  }
}

function setNotBusy() {
  isBusy = false;
  serviceQueue();
}

Can it still be related to the dongle i use?
