Has anyone had success with samples/bluetooth/beacon on this device?

Even the nitrogen_beacon.hex file from 96boards.org won't transmit. The
console messages are as expected, but nothing on the air. Same results
on two recent boards from Seeed.

The same .hex file flashed to a redbear ble nano2 does transmit. There
is no console output because a different uart is used, but the beacons
are on the air.

The designation on the nRF52 is N52832/QFAAB0/1616BD. I looked at the
errata and didn't see anything obvious.

I'm waiting for a reply from Seeed as to what they use to test the ble
functionality of the devices before they ship.

As a last resort, I'll try Nordic's SDK and see if I get the same
results.

Thanks,

Steve
