  • hi,
    I am trying to send midi cc only on motion detection, but I get nothing coming and the terminl issue me an error: WARNING: SD ERR 0x11 (BUSY) (:835)

    I am using require("puckjsv2-accel-movement").on();­ and suspect I am using setservices twice then which could be the problem? but not really sure where to look at.

    here is the code:

    require("puckjsv2-accel-movement").on();­
    
    /// Sends a raw MIDI command
    function cmd(cmd, d1, d2) {
      NRF.updateServices({
        "03B80E5A-EDE8-4B33-A751-6CE34EC4C700": {
          "7772E5DB-3868-4112-A1A9-F2669D106BF3": {
            value: [0x80, 0x80, cmd, d1, d2],
            notify: true
          }
        }
      });
    }
    
    /// Send a 'control change' (0xB0) MIDI command
    function midisend(channel, controller, value) { cmd(0xB0+channel,controller,value); }
    
    
    
    function rescaleToMidiCC(value, oldMin, oldMax) {
      var newMin = 0;
      var newMax = 127;
      var rescaled = Math.round((value - oldMin) * (newMax - newMin) / (oldMax - oldMin) + newMin);
      rescaled = Math.min(127, Math.max(0, rescaled));
      return rescaled;
    }
    
    
    
    /// Turns the device into a MIDI controller
    function init(name) {
      //NRF.setSecurity({passkey:"123456", lesc:1, bond :1});
      NRF.setServices({
        "03B80E5A-EDE8-4B33-A751-6CE34EC4C700": { // MIDI
          "7772E5DB-3868-4112-A1A9-F2669D106BF3": {
            readable: true,
            writable: true,
            notify: true,
            value: [0x80, 0x80, 0x00, 0x00, 0x00]
              }
        }
      });
      NRF.setAdvertising([

    init("PuckOI");
    
    
    var idleTimeout;
    var active;
    Puck.on('accel',function(a) {
      LED.set();
      active = true ;
      if (idleTimeout) clearTimeout(idleTimeout);
      idleTimeout = setTimeout(function() {
        idleTimeout = undefined;
        LED.reset();
        active = false ;
      },1000);
    });
    
    if (active) {
    print("yes");
    //Puck.accelOn(); // default is 12.5Hz, with gyro
    //Puck.accelOn(1.6);// for 1.6Hz low power, without gyro
    // Turn events off with Puck.accelOff();
    
      const accel = Puck.accel();
      var x = ((accel.acc.x/128000)*10) *127;
      var y = ((accel.acc.y/128000)*10) *127;
      x = rescaleToMidiCC(x, -80, 80);
      y = rescaleToMidiCC(y, -80, 80);
      midisend(0,1,x);
      midisend(0,2,y);
    }
