BLE Connect/Disconnect

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){
       uart.write("digitalWrite(LED1, 1),digitalWrite(D28, 1);\n");}
       if (avrY > 105){
       uart.write("digitalWrite(LED1, 1),digitalWrite(D29, 1);\n");}

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

  }
      
  

});
