Can't locate device by Name - solved with longer scan - Tilt

Hi,
I have a digital hydrometer - a device called Tilt.

On the iphone - using the nrf scanner app - I can see:

{
kCBAdvDataIsConnectable = 1;
kCBAdvDataLocalName = Tilt;
kCBAdvDataServiceUUIDs = (
"A495FF10-C5B1-4B44-B512-1370F02D74DE",
"A495FF10-C5B1-4B44-B512-1370F02D74DE"
);
kCBAdvDataTxPowerLevel = 4;
}

I try to scan from the puck:

>NRF.requestDevice({ filters: [{ name: 'Tilt' }] }).then(function(device) {
:   console.log(device);
: });
=Promise: {  }
Uncaught Error: Unhandled promise rejection: No device found matching filters
> 

NRF.connect takes a address - but I don't know what the address of the device is - none of the NRF apps appear to show the address.

Any ideas how I can connect to this device?
