GATT connection timeout?

Here it is:
Please note DevName,serviceUUID,characteristicUUID and MessageToSend have been replaced in the code below because of confidentiallity agreement.

var devices;
var gatt;
var DevName="MyActuator";

var serviceUUID="2fc3af42-7a4a-1431-d1f1-fs5­51e3bf022";
var characteristicUUID="32160fb9-5337-4e71-b­0f8-ff412e3ae078";
var MessageToSend=[0x00,0x01,0x03];


function scan(){
  NRF.findDevices(function(d) {
    devices = d;
    console.log(devices);
  }, 5000);
}

function SendCommandToActuator() {
  NRF.requestDevice({ filters: [{ name: DevName }] }).then(function(device) {
    return device.gatt.connect();
  }).then(function(g) {
    gatt = g;
    console.log(gatt);
    return gatt.getPrimaryService(serviceUUID);
  }).then(function(service) {
    return service.getCharacteristic(characteristic­UUID);
  }).then(function(characteristic) {
    return characteristic.writeValue(MessageToSend)­;
  }).then(function() {
    gatt.disconnect();
    console.log("Done!");
  });
}

function Bond(){
  NRF.requestDevice({ filters: [{ name: DevName }] }).then(function(device) {
    console.log("found device");
    return device.gatt.connect();
  }).then(function(g) {
    gatt = g;
    console.log("connected");
    return gatt.startBonding();
  }).then(function() {
    console.log("bonded", gatt.getSecurityStatus());
    gatt.disconnect();
  }).catch(function(e) {
    console.log("ERROR",e);
  });
}

When I load this script and I call SendCommandToActuator(), I get this log:
