https://devzone.nordicsemi.com/f/nordic-q-a/20798/getting-started-with-wearable-development-using-nrf51822Hi, my first post here. I&#39;m a undergraduate student and newcomer to this field. I&#39;ve some programming background but few in electronics and embedded systems (so probably this question will be to silly for most of us). I would like to learn and understanden-USTelligent Community 13Mon, 27 Mar 2017 11:19:07 GMThttps://devzone.nordicsemi.com/thread/81228?ContentTypeID=1Mon, 27 Mar 2017 11:19:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c73c6bd3-4a12-48ac-80db-246965ba11c3AlexRay<p>Thank you so much for your answer.

Once you master nRF5x architecture and firmware development (either based on Nordic&#39;s nRF5 SDK - which I recommend - or ARM mbed or other) then building basic prototype from development kits and breadboards/jump wires is usually enough to develop the basic functionality. Then if you would ever move to production it&#39;s long story of costom dev kits (simulating your platform in more compact form factor allowing debugging in almost real-life scenarios) and HW iterations, testing (functional testing like BLE DTM, power profiling, radio emissions etc.), certifications (typically FCC, ETSI, BT SIG, CE...), productization in some Contractual Manufacturer, Qaulity Control...</p><div style="clear:both;"></div>
