This can be done both with nrfjprog and nRFgo Studio, both of which should be able to use any external J-Link.

Hello Mr. Morten,

Kindly suggest how soft device hex file can be loaded in custom board using J-link lite cortex m.

Regards

Talha

The difference between the Evaluation Kit and the Development Kit is described better here.

As for programming custom boards, the J-Link you link to should work fine, as should the J-Link in the Development Kit as long as your custom boards run at ~3 V. When you buy either kit you get a Product Key that you can use to access the softdevice, and use it on any custom boards.

Making a custom board isn't really very hard, but you need to make sure to copy the reference layout as close as you possibly can. Even tiny changes to it can severely affect the RF performance, both with regard to range and compliance with regulatory rules.

I'll second the recommendation for the dev kit. It's got the Segger debugger included along with 5 chips for your custom board.

As Marc said, it's not totally trivial to do a custom board. However, I've done it and it does work (although only at about 15 foot range) and I know nothing about RF design (or electronics really as some of my other posts demonstrate :).

I've got an open source project that might be of use: http://hg.cmason.com/nrf

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.
