What is the nRF52-DK used for in this special Nordic-out-of-the-box example ?

[betzebubi]

Hello,

on GitHub I foudn an out of the box example for bluetooth mesh with multiple Thingy-boards ( https://github.com/NordicPlayground/Nordic-Thingy52-mesh-demo ). The description says, that a nRF52-DK is needed to realize this project but I can't find it's use further on in the text. 

So what is it used for? 

And also I've not understood how to flash the software on the thingy-boards. How can I connect them with my computer? Is the nRF52-DK necessary to do this? 

Thanks

hello betzebubi,

Yes, as per the github README.md requirements, either a Nordic nRF5x-DK or Segger J-Link debugger is required (or I should say the easier way) to flash firmware to the Nordic-Thingy52.

See this post and this post for further details..

just a small addition to leanwj perfect answer. 

Thingy52 does not have OBD (On Board Debugger), So you need an external debugger to connect to the SWD lines of the thingy to flash new firmware. We normally use nRF-DK to program other devices with SWD lines due to debug-out lines gives on the DK makes it easy for us to do.

You can use any other external flasher instead of nRF-DK, with and SWD interface to flash Thingy52
