I picked up a Thunderboard Sense at Embedded World 2017 last week (sticker says BRD4160A Rev B01). Testing it at our lab here unfortunately it appears DOA:
Tried powering with 2 known good batteries
The iOS app does not find anything over BT
The computer does not find anything over BT
Also tried powering via USB:
Simplicity 4 does not find any device.
Is the board DOA? How do we get a replacement?
Have you tried pressing all the buttons? A green light blinks meaning it is advertising. It can then be found on the app.
When I plug my sense into PC a blue light comes on?
If not I guess it is dead.
Confirmed that board is dead.
Have been in touch with SI labs (and also ordered a new one via RS Online)
The board was dead. We replaced it. The new is confirmed to work.
