NRF.setAdvertising 'name' and 'iBeacon'

When you specify an array of numbers to advertise, that's the actual data that gets sent out, so even though you set the name it won't show.

You can see in my reply above though I do NRF.setAdvertising([ binary_data, {} ], { name:"Hello", ... })

The important thing there is the {} as it says to Espruino that you want to advertise two packets, interleaving them. One is the binary data, the other is what Espruino makes based on name - so in that case it should show up
