If you want to have a different look at exactly what your nRF51822 and application code
are transmitting over the air, or if something doesn't look quite right to you, you can
also try using any of the debug tools discussed in
Chapter 6

Going Further
Embedded development is a huge field, touching on a wide variety of domains. It in‐
volves physics with radio signal propogation and antenna design, electrical engineering
with hardware design and part selection, mechanical engineering and industrial design
with enclosures and overall product development, embedded software development for
your firmware, manufacturing knowledge to source parts and assemble hardware, and
effective test and validation strategies to make sure it doesn't all come back to you pre‐
maturely.
This tutorial covers only the tiniest part of embedded development, focusing on firm‐
ware design, but if you're interested in design and developing your own embedded
hardware, there's probably never been a better time to get started, regardless of your
technical background. Costs are coming down, information on both hardware and
firmware development, as well as manufacturing know-how, have never been more
accessible, and entire online ecosystems exist around these technologies.
If you're interested in going further with embedded development, take a look at some
of the great open source hardware communities that have grown roots over the years,
every day. Communities like this might get the ball rolling in your own head, or expose
you to some ideas or technologies you might not have been familiar with before.
Nordic Semiconductor's also has a helpful
Nordic Developer Zone
forum, which can
be a great source of answers to common problems working with this chipset.
