nRF51822 programming question

Max

Hi,

I am starting my first project with nRF51822 for my thesis. I thought its a good idea to start with evolution kit so I bought nRF51822-EK I assume I will get everything I need to write my first application and should be able to talk to iPhone app. I am writing iPhone app for proximity sensing. Am I correct till this point?

Now my question for future design. I will be using 7-8 custom boards in my project. These board will be very simple just nRF51822 chip and some passive components. How do I program these custom boards?

Do I just buy this J-LINK? www.digikey.com/.../2263130

Will I be able to use SoftDevice binary that includes the bluetooth stack with my custom boards? Will there be any license issue if I am using it on my custom bords?

I will appreciate any comments on this. I am early in my development cycle but I would like to know all the road block sooner rather than later.

Thanks, Max

    Hi Max,

    The EK is a great place to start and you'll be able to prototype a proximity app just fine with it (that was me about 18 months ago :) ).

    With regard to the custom boards, I want you to be aware that rolling a custom board isn't as straight forward as you might be tempted to think. Antenna/impedance matching is somewhat complicated, although you can send the boards to Nordic and they'll help with that matching network. Be aware that none of the reference designs show a matching network in place!

    If your project is low volume, maybe look at something like the RF Digital nRD51822? It's a nRF51822 on a tiny PCB with modular approval, an RF shield and a well-matched antenna.

    For a J-Link, I'd recommend getting the nRF51822 Dev Kit. It comes with a bare bones J-Link that's only licensed to program Nordic parts. At $99, it's a heck of a deal.

    Someone from Nordic should answer the SoftDevice question 'officially', but I believe you're entitled to a license for the SoftDevice and SDK for every piece of silicon you buy. So you're fine.

    Hope that helps.
