Hi Peter,

Feel free to ask us any kind of questions so that we could help you get a better understanding. Sorry again to hear about this experience. Thank you for your feedback so far, I will provide feedback to the responsible teams both regarding the getting started experience in general and also about highlighting the recommended settings for SW9 for the DK.

Next step

Now, it is great to hear that you got one step further. In case you would like to proceed, and have not tried this yet, a next step would be to run a test and program the Heart Rate Monitor onto your nRF5340 DK.

'nRF Connect SDK', 'nRF Connect for Desktop' and 'nRF5 SDK'

Something that could be confusing when you are new to our products is that there are two different SDK's. The old one, which is still in use, is called 'nRF5 SDK'. The future, however, is the new SDK called 'nRF Connect SDK', sometimes referred to as "NCS". Our new devices, nRF5340 and nRF9160, are only compatible with the 'nRF Connect SDK'.

Please also note that we also have a bucket of useful and necessary development tools which is called 'nRF Connect for Desktop'. This is not the same as 'nRF Connect SDK'. If you have not installed 'nRF Connect for Desktop' yet, links to instructions are found in the getting started guides.

Getting started with nRF53

Here is a starting point for nRF53: Getting started with nRF Connect SDK (nRF53 Series)(pdf). The same getting started guide is also available as a web page on Infocenter.

The nRF Connect SDK Getting Started guides here on DevZone includes detailed instructions for building applications for the nRF5340 (and nRF9160). Among the tutorials you will find this series, part 0-3:

nRF Connect SDK Tutorial series - Part 0 | NCS v1.4.0

nRF Connect SDK Tutorial - Part 1 | NCS v1.4.0

nRF Connect SDK Tutorial - Part 2 | NCS v1.4.0

nRF Connect SDK Tutorial - Part 3 | NCS v1.4.0

The tutorials are written for NCS v1.4.0. It is fine to go through these tutorials and then upgrade to NCS v1.5.0 afterwords.

Webinars

An upcoming webinar will be discussing the features and benefits of the nRF Connect SDK: 'Understand the nRF Connect SDK'.

Recordings of previous webinars are also available.

Thanks again for your feedback and please talk to us when things are unclear.

Best regards,

Håkon

Hi,

Finally got it connected - but I'm afraid the whole experience of trying to do anything with the nRF5340 is just too difficult so I'm reverting back to using ST components and development kits. You website and documentation is all very nicely presented and slick, but unfortunately of no use whatsoever in actually finding out and setting up a dev kit for the first time. You simply get directed round and round - I can't find one single example of how to get something runing end-to-end - not even blinky. Sorry, just too difficult - and if it takes me days and is incredibly frustrating even just to get going I'll simply use something else. So - looks like £90 down the drain for 2 nrf5340 and about a week of wasted effort - I had hoped to find an improvment to ST dev kits - sadly this definitiely isn't it. Lesson learned.

Best regards

Hello

Welcome to DevZone. Sorry to hear you are having this experience even before getting started. Hopefully we will figure this out together.

Have you tried setting SW9 to "VDD". This is the default setting. I took out an unused DK (HW v0.10.0) and tested that VDD works. If I switch over to "USB", then the demo does not work. However, there is a faint/flickering light in the LED next to the IC with the chip with the PCA10095 sticker. I understand that one may select "USB" when connecting the DK to USB, however, it do not think this is the case. The DK has a sophisticated and highly configurable power solution that allows for a broad range of use cases.

Which HW version of the nRF5340 DK are you using? The version number is shown below "PCA10095" on the white sticker.

Also, at this stage, you probably would want to connect the DK to your computer using micro USB connector J2, which is on the short side of the DK.
