    Hi Gordon,

    first of all thank you very much for the information, I didn´t know that.

    I have two more questions about this. If I delete this lines:

      if (avrX > 90){
       uart.write("\x03\x10digitalWrite(LED1, 0), digitalWrite(D31, 0);\n");}
       if (avrX < 105){
       uart.write("\x03\x10digitalWrite(LED1, 0),digitalWrite(D27, 0);\n");}
       if (avrY > 90){
       uart.write("\x03\x10digitalWrite(LED1, 0),digitalWrite(D28, 0);\n");}
       if (avrY < 105){
       uart.write("\x03\x10digitalWrite(LED1, 0),digitalWrite(D29, 0);\n");}

    I don´t get any feedback in the console. If I let it in, I get this message, even if it works with the connecting/disconnecting thing:

    Uncaught Error: Unhandled promise rejection: Error: BLE task CHAR_WR is already in progress

    The other thing is I try to implement now the button and the part of the code for the button works in another program and also if the Accel is not in that one. What is the issue, when I want to use that additional code? Is it that uart.write is busy in some way? Sometimes the signal from the button receives the MDBT but after 2 or 3 times it stops or the LED on the MDBT does not go off again.

    Here the complete Code:

    var log = print;
var uart;
var l;
var connected = false;
var avrX = 0;
var avrY = 0;
var accZero = Puck.accel().acc; // get the base value when we start up

///BLE Connect


    function flag(e) {

    var l = e.time-e.lastTime;
    if ((l < 0.3) && (connected == false)){
    log("Sending command");
    log("Searching for device...");
    NRF.requestDevice({ filters: [{ namePrefix: 'MDBT42Q' }]
    }).then(function(device) {
    log("Connecting...");
    device.on('gattserverdisconnected', function() {
    uart = undefined;
    connected = false;
    });
    return require("ble_uart").connect(device);
    }).then(function(u) {
    log("Connected");
    digitalPulse(LED3, 1, 300);
    uart = u;
    connected = true;
    log (connected);
    });}

    if ((l < 0.3) && (connected == true)){

    if (uart) uart.disconnect();
    uart = undefined;
    connected = false;
    log (connected);

    }


    }
    setWatch(flag, BTN, {repeat:true, edge:"falling"});

Puck.accelOn();


Puck.on('accel', function(data) {


  avrX = (avrX*0,99) + 0.01*(data.acc.x - accZero.x);
  avrY = (avrY*0,99) + 0.01*(data.acc.y - accZero.y);
///log (avrX, avrY);

 if (connected == true) {

       if (avrX < 90){
       uart.write("\x03\x10digitalWrite(LED1, 1), digitalWrite(D31, 1);\n");}
       if (avrX > 105){

 }

    Ah and one more info, the re-connection works basically but the signals will not be sent to the MDBT42Q. The LED there is not reacting anymore after the reconnection.

    I get this message now in the console with BLE task 3:

    0
false
Uncaught Error: Unhandled promise rejection: Error: BLE task 3 is already in progress

    Hi Gordon,

    thanks for that help.

    What I found out is, if I delete the part with the accelerometer it works. I can connect and disconnect like it should be all the time.

    Did I made a mistake in the accelerometer section? I ask for
    if connection is true, uart.write.

    var log = print;
var status = 0;
var uart;
var l;
var connected = false;
var avrX = 0;
var avrY = 0;
var accZero = Puck.accel().acc; // get the base value when we start up


//BLE Connect

    function flag(e) {
  
    var l = e.time-e.lastTime;  
    if ((l < 0.3) && (connected == false)){
    log("Sending command");
    log("Searching for device...");
    NRF.requestDevice({ filters: [{ namePrefix: 'MDBT42Q' }]         }).then(function(device) {
    log("Connecting...");
    device.on('gattserverdisconnected', function() {
    uart = undefined;
    connected = false;
    });
    return require("ble_uart").connect(device);
    }).then(function(u) {
    log("Connected");
    digitalPulse(LED3, 1, 300);
    uart = u;
    connected = true;
    status = 1;
    log (status);
    log (connected);
    });}


    if ((l < 0.3) && (status == 1)){ 
      
    if (uart) uart.disconnect();
    uart = undefined;
    connected = false;
    status = 0;
    log (status);
    log (connected);
    }

    
      
    }
    setWatch(flag, BTN, {repeat:true, edge:"falling"});




///Accelerometer



Puck.accelOn();


Puck.on('accel', function(data) {
  

  avrX = (avrX*0,99) + 0.01*(data.acc.x - accZero.x);
  avrY = (avrY*0,99) + 0.01*(data.acc.y - accZero.y);
///log (avrX, avrY);

 if (status == 1) {

       if (avrX < 90){
       uart.write("digitalWrite(LED1, 1), digitalWrite(D31, 1);\n");}
       if (avrX > 105){
       uart.write("digitalWrite(LED1, 1),digitalWrite(D27, 1);\n");}
       if (avrY < 90){

       if (avrY > 105){

       if (avrX > 90){

    I have a little problem that I'm stuck on.

    What I basically want to do is:

    1. with a short press of the Puck.js <0,3s a Bluetooth connection to the MDBT42Q should be established >>> works.
    2. directly after the connection, the accelerometer should execute its function and switch various pins on the MDBT when the threshold values are exceeded >>> works
    3. when pressing the Puck.js again < 0,3s the Bluetooth connection shall be disconnected again.

    When I upload the code it either doesn't work at all or once and then not anymore.

    I get following in the Console:

    Uncaught Error: Unhandled promise rejection: Error: BLE task 6 is already in progress

    Did I understand this correctly? The characteristic 039afff8-2c94-11e3-9e06-0002a5d5c51b stands for the transmission of the signal status, power spectrum and eSense (attention/meditation) but it is not sent publicly? So, one will not receive anything or see the received content?

    But I have another question.

    Any idea how I can get x/y starting at 0 with a non sensitive movement tracking?
    The raw values changing very fast.

    I would like to use the Puck.js as a Joystick.

    Best regards
