Trying to understand BLE advertising

Hi All,
I'm amazed by the capability of this little device and suspect I'm trying to have my cake and eat it, but I'm looking for a way to advertise an iBeacon, services and services data all at the same time. I'm almost there, but at the moment I can only have services and service data advertised, or service data and iBeacon.

My application has the puck providing a number of services and characteristics including battery, light and temperature and a button service. These are set up with a call to NRF.setServices that specifies the advertising in the options e.g.

{
  advertise: ['180A','180F','181A','87100001-703F-4AEE-A323-9AE013D98E93']
}

I'm then using a call to NRF.setAdvertising to create the service data advertisement e.g.

NRF.setAdvertising({
    0x1815 : [button.single, button.long],
    0x180F : [metrics.battery],
    0x1809 : [metrics.temperature],
    0x181A : [metrics.light]
  },{ interval : 375 });

These two work together fine. I start the iBeacon using NRF.setScanResponse, e.g.

NRF.setScanResponse(require("ble_ibeacon").get({
    uuid : beaconUUID,    // iBeacon uuid
    major : beaconMajor,  // optional
    minor : beaconMinor,  // optional
    rssi : -59            // optional RSSI at 1 meter distance in dBm
  }));

The beacon works but it seems to stomp on the advertisement for services specified in the NRF.setServices() options, as these disappear. (the service data advertisements continue).

Is there some way I can use arrays in NRF.setAdvertising to specify all three advertisements, services, service data & iBeacon?

Cheers
Dave
