If I had to choose one significant aspect that I was not aware of before starting my career as a firmware developer, it would be how much time is spent **not actually developing** , and instead **debugging** firmware!

Thanks for this concise and useful post, which is actually about much more than debugging, as you show exactly how to set up a development environment. I expect that this will reduce the pain of embedded development for many newcomers.

I’m looking forward to the next post about debugging nRF applications with SoftDevices. Please hurry! 😄

Or if possible, perhaps reply with a few pointers about how to do that.

Thanks, Karl!

I’m hoping to post the article on debugging SoftDevice-based nRF applications soon. In the meantime, you may want to check out the following links:
