Confused by versions

[Bret Foreman]

OK, there are multiple versions of:

• nRF51 chi
• PCA10028 dev board
• example projects
• SDK
• soft device
• Keil dev environment

I getting all sorts of errors about the example projects referencing files that are not installed. If I hit OK through all those errors then the project builds. But when I try to download the hex file I get errors about the download failing.

My dev board is the PCA10028 version V1.1.0 The Nordic chip has the following printed on it:

NS1422

QFACA1

1503A0

My SDK is version 9.0.0

My version of Keil is MDK-Lite Version: 5.16a

My dev board is loaded with the S110 softdevice that came with the SDK. I'm not sure how to report the version of that.

What have I got wrong?

Attempting to download the hex file to the target yields this message, which looks like it's trying to download to the wrong device:
