Since I wrote about CrossWorks a few weeks ago, several people have mailed me and asked me if I have any sample projects. I didn't, so I just created some.
I've created projects which build blinky_example and ble_app_hrs for each of the three boards NRF6310, PCA10001 and PCA10000.
The projects follow the same directory structure that Nordic's examples do and are designed to unpack into the SDK directory (if this concerns you please make a copy of it first). So for instance the current nrf6310 blinky_example directory looks something like this
Board/nrf6310/blinky_example /arm/ /gcc/ /iar...
Updated version here (21.04.15): https://devzone.nordicsemi.com/tutorials/7/development-with-gcc-and-eclipse/
I have noticed that there have been several questions on development with Eclipse and GCC, and I have also been trying myself for quite some time to make it work properly. It finally seems like I have figured out an approach that works for me. I.e., successfully importing and debugging of example projects from the nRF51 SDK. So I thought I could make a blog post to share my setup and hopefully help others who are also new to Eclipse and GCC.
Inspired by other devzone...
Atomwear is a micro, modularized, open source, wearable BLE device for DIYers. It makes any BLE(Bluetooth Low Energy) projects easier
Overview - What’s the Atomwear?
Atomwear is a BLE product based on a Nordic BLE chipset. It’s different from other wrist straps available in the market, such as gearfit and jawbone.
Atomwear is designed specifically for DIYers. just like building blocks for kids, Atomwear components allow you to build it into whatever you like, be it a bracelet or otherwise!
Atomwear is fully open source. The aim of Atomwear is to speed up your development cycle. Choose Atomwear...
You may have a nRF51 chip that is "bricked" and both nRFGo Studio and nrfjprog recover option doesn't work. You can try to use J-link Commander to recover. In some case, J-link Commander showed that it can recover the chip when nrfjprog and nRFGo Studio couldn't.
Jlink Commander should be installed automatically when you install Jlink driver. Here is the screen when you start J-Link Commander and select the J-link programmer (if you have more than one):
When you have the command line ready you can type:
w4 4001e504 2
w4 4001e50c 1
w4 4001e514 1
I created this blog post to document the bugs reported on nRF51 SDK v6.0.0
The workaround for each bug would also be provided here as a temporary solution before the bug is fixed in the future release of the SDK.
Our most advanced Bluetooth Smart SoftDevice to date is now - S130. We're excited in a big way about this one covering as it does so many different options in one protocol stack.
Again, we always value feedback from you guys toiling hard out there making great and cool stuff that the world gets to see and use, or just making things because it's fun and cool. So please let us know here - what's great, what's not, improvements, tweaks, it's all great for us, and you in the long run.
cheers, The Nordic Team

Configuring a project for CMSIS-DAP debugger:
Open a project in Keil, and go to Options for Target, and select CMSIS-DAP Debugger under the debug tab:
Check that the "Use Debug Driver" is checked under Utilities tab:
Now go into the debugger settings and verify that the nRF51xxx programming algorithm is chosen:
Go to tab "debug" and see that the debugger and device...
If you bought nRF51822 Development Kit and want to quickly and easily begin development without the need to own nRFgo Starter Kit, you can check the BLE DEVKIT.N R2 main board at ebay. More information and documentation you can find at the product page here.

Do you not use Windows but OS X or Linux? Do you use Windows but find the old tools expensive and terrible to deal with? Are you a hobbyist who doesn't have $2000 and an annual fee to spend on a toolset you don't like?
I am some of those things. I'm an OS X user, I don't love using parallels unless I can't help it, I find Keil to be a pretty poor product (sorry Keil but I do) and way beyond what I'm prepared to spend to fund a hobby.
Apple’s newest technology known as iBeacon has taken the retail world by storm, and should definitely be considered as a mobile marketing tactic for all companies. iBeacon is an indoor positioning system retailers use to notify nearby IOS device users of their presence. iBeacon also sends push notifications or text messages to customers letting them know about special promotions companies are offering. Customers can even search for specific items using iBeacon to find the best deals at the closest locations. The best part about the iBeacon technology is that it is low cost, making mobile marketing easy to afford...
Over the last few months, work has been done to create a new Developer Zone on a more robust and future-proof foundation. Today, we're finally launching the result of this effort.
We've been tremendously happy with the way the community have built on this site over the past year or so a lot stays the same:
Programming and debugging the nRF5x on our Developments kits is straight forward. Doing the same when you are using other boards might not be so easy. In this blog post we will explain which components are needed in order to program and debug a nRF5x chip.
The nRF chip is connected to a Debug unit through an interface called "Serial Wire Debug", or "SWD" for short. The debug unit acts as a bridge between the chip and your PC. It communicates with the programming and debugging software on your PC through a “Debug interface”. Your PC must have a driver...
