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

    I found this
    https://wiki.makerdiary.com/nrf52-u2f/bu­ilding/
    and this

    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);
            }
          },

            }
          }
        }
      });
    }
    
    setService();
    
    function advertise()
    {
      var voltage = Math.round( NRF.getBattery() * 1000)/1000 ;
      voltage = voltage.toString();
    
      var data = {
        0x180F : [Puck.getBatteryPercentage()],
        0x1801 : [ voltage.split('') ],
        0x1809 : [Math.round(E.getTemperature()+1 /*device specific offset*/)]
      };

    Hi,

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

    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.

    With both of them. I already increased the

    setTimeout(job, 1000);
    

    to 2000 without success.

    I will try this command later:

    Its a

    2. ID 050d:065a Belkin Components F8T065BF Mini Bluetooth 4.0 Adapter

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

    The dongel has Bluetooth 4.0 and not 4.1.

    With a Raspi 3.0 its working.

    I cant send a write command to the puck:

    <Config> Config loaded
    <MQTT> Connecting...
    <HTTP> Server is listening on 1888
    <MQTT> Connected
    <HTTPProxy> Bleno State poweredOn
    <HTTPProxy> Bleno.startAdvertising Success
    <HTTPProxy> Bleno.setServices Success
    <Discover> Starting scan...
    <Discover> Scanning started.
    <MQTT> /ble/write/e9:05:8c:a7:64:ab/nus/nus_tx => "digitalPulse(LED3, 1, 200);\n"
    <Discover> Scanning stopped.
    <Connect> e9:05:8c:a7:64:ab: Connecting...
    <Connect> e9:05:8c:a7:64:ab: Error Connecting: Error: Command Disallowed (0xc)
    <Discover> Scanning started.
    

    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?

    If i install the the espruino module local and not global it works:

    :~/Downloads/espruino$ node node_modules/espruino/bin/espruino-cli.j­s 
    Espruino Command-line Tool 0.0.36
