Bonding process between a Puck.js and another BTLE peripheral

Hi there,

I am trying to use the Puck.js as a central device, connecting to a peripheral device (BTLE actuator).
I suppose that the procedure is as following:

1. NRF.requestDevice() with either name or id of the peripheral device already known and used as filter
   
2. connect the gatt
   
3. bond with .startBonding
   
   

Whenever my Puck.js executes the gatt.connect(), I have 2 problems appearing: First one is that the Puck.js disconnects from the IDE, and second one is that connection fails with error "ERROR Connection Timeout".

I tried to execute the code found here http://www.espruino.com/Reference#l_Blue­toothRemoteGATTServer_startBonding

var gatt;
NRF.requestDevice({ filters: [{ name: 'My BT actuator name' }] }).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);
});

First step of requesting the device seems to be OK as I can read found devicein the console when the puck.js doesn't disconnect from the IDE.

Any idea on what goes wrong?
