Microbit signal data out over bluetooth?

@Pierre, the following would appear to work:

NRF.setAdvertising({
  0xFEAA : [
  0x10, // frame_type (URL)
  0xEE, // the RSSI dBm we've measured for this beacon 1 meter away
  0x02, // 2 = http://
  112, 117, 99, 107, 45, 106, 115, 0 // puck-js.com (0 = .com)
  ]
})

At least the Nordic tools pick it up as being an Eddystone beacon... However the Physical Web app doesn't seem to. I'm checking up on why, and I'll let you know what I find.
