How to create custom service and characteristics

Hi,

I've read the various tutorials and examples about how this should work, but I just don't seem to be able to get it right.

If I use the nrF Connect app on my iPad, connect to the Puck it shows the expected UART service with TX/RX.

If I connect via TinyB, BLE command line I see two services listed:
1) The expected one for UART: 6e400001-b5a3-f393-e0a9-e50e24dcca9e
2) Another one: 00001801-0000-1000-8000-00805f9b34fb (what is this one?)

If I try to add my own service and specify UART:false on the options then the iPad won't connect to the puck at all and the code version still either sees 1 or both of the previously mentioned service uuids.

I'm trying to use the sample code like this:

RF.setServices({
  "0000bcde-0000-0000-0000-000000000000" : {
    "0000abcd-0000-0000-0000-000000000000" : {
      value : "Hello", // optional
      maxLen : 5, // optional (otherwise is length of initial value)
      broadcast : false, // optional, default is false
      readable : true,   // optional, default is false
      writable : true,   // optional, default is false
      notify : true,   // optional, default is false
      indicate : true,   // optional, default is false
      description: "My Characteristic",  // optional, default is null
      onWrite : function(evt) { // optional
        console.log("Got ", evt.data);
      }
    }
    // more characteristics allowed
  }
  // more services allowed
},{advertise:['0000bcde-0000-0000-0000-000000000000'], uart:false});

I would expect to only see the one service listed and connection from iPad should work too.
Also are then any more details about what the various attributes mean ie:

  broadcast : false, // optional, default is false
  notify : true,   // optional, default is false
  indicate : true,   // optional, default is false
  description: "My Characteristic",  // optional, default is null

I also don't see any way to retrieve the description detail via TinyB,
http://iotdk.intel.com/docs/master/tinyb/classtinyb_1_1BluetoothGattCharacteristic.html

Quite often I also find that the Puck vanishes or won't connect and I constantly need to either reset it AND or run /etc/init.d/bluetooth restart to keep things running. I've ensured all the libraries are up to date.

Another note is that in the console of the WebIDE I get the message:

BLE Connected, queueing BLE restart for later

If I try to put the setService in a timer then that message is written out every time it fires.
