nRF51822 Beacon does not show up on nRFgo Studio

[Sarah]

Hi,

I'm using nRF51 Development Kit to program the beacons. I've connected the beacon just like it's described in the last update of this thread using the 10-pin adapter cable. However, in the device manager of nRFgo Studio, the beacon does not show up and nRF51 Programming tab is not accessible, so I'm not able to program the beacon. What am I doing wrong?

Thanks.

The beacon does not show up as a separate device if you are using the nRF51 DK. In nRFgo Studio there will be no difference whether you flash the DK or the Beacon through the DK. The DK will automatically pass through to the debug out port if it senses any devices on that port.

Thank you. How can I fix the nRF51 programming tab not being available and do I really need this tab? Segger does seem to appear under nRF Development boards (I installed nRF Go and it automatically started installing the nRT Tools app which includes the JLInk driver). And when I try to upload my application the first time I get "device not found error" but if I retry it seems to complete successfully. Is this just a connection issue?

Also, How can I make sure then, that it's the beacon I'm programming and not the DK? It looks like the beacon is not getting programmed (cannot erase it and properties seems to stay the same on the beacon when I change them) and I couldn't figure out why.

So, the programming tab is just for separate J-link programmers. You don't need this tab to be available if you are programming something through the nRF51 DK.

If you get a "device not found" error, you should check the connection, and also he power to the device.

I don't think there are any way to tell if you are programming the DK or the device through the debug out port. I guess you just have to assume that when you connect something it senses that there is an external device there, given that the external device has power. You could make a quick check though: Flash softdevice 8 to the DK. Then connect the other device. Flash SD 7. Disconnect the external device. Reopen nRFgo Studio. If you now see softdevice 8, it means you flashed softdevice 7 to the external device. If you see softdevice 7, it did not flash the external device.

Thanks very much for your reply, the problem turned out to be the connector I'm using to connect the beacon kit. It all works fine with the new connector!
