Did you use it before and maybe flash something different? If yes, then remove the battery and press the button. Then put in the battery again and within 3 seconds release the button. Then it would omit any program you may have on the puck.
Otherwise I would try re-installing the firmware. The procedure is documentation in the getting started.
Thanks for the reply. They are both out of the box unmodified, not flashed pucks. I tried following the instructions for re-installing the firmware but the puck doesn't show up in the nRF Connect application during a scan. It looks to me like the puck's bluetooth isn't working.
