It's for sure not 5V, there's a solder jumper that selects voltage (set to 3.3V), but the silkscreen always says 5V. Don't worry.

Another option than hacking a button on your board as shown above would be to use an example that is discoverable without a button press. This should include most of the Development Kit examples, for example ble_app_hrs and ble_app_proximity.

PS: From the silkprint in your picture, it could seem as if you're feeding your nRF51822 5 V. That way outside spec (1.9-3.6 V), so I hope it just looks that way from the picture, and that you aren't actually doing it. Apart from that, very nice hack! :-)

Yea... well I kind of wanted more nRF chips and a detached J-Link

This is what I ended up doing http://i.imgur.com/ChFMyuD.jpg

Go ahead and laugh

Note that there is also an Evaluation kit that can be used without a motherboard. https://www.nordicsemi.com/eng/Products/Bluetooth-R-low-energy/nRF51822-Evaluation-Kit

I am stupid

I don't own the motherboard. I needed to press a button to start the advertising.

Problem solved, I soldered a button to the board. I got it to discover.

I didn't even know I needed to buy a motherboard... This kit already costs more than $100...

Hi Sebastien

Thanks for the reply

The nRFgo Studio software is pretty clear on which Segger J-Link was used. But I did try again after disconnecting the PCA10000 dongle, then reflashing the PCA10004. Still nothing being discovered.

Note: I can run DTM in transmit mode, and see appropriate spikes on my spectrum analyzer (a RF Explorer, nothing fancy), so the radio is working...

I don't know if it could help, but I think that you can't have the Segger board for chip programmation and the donggle USB used at the same time. Try to disconnect the Segger.
