New Developer Zone

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:

  • You can use your old username and password (although hash algorithm is improved).
  • All features from the old site should still be here.
  • All questions, answers, comments and private messages are converted and still available (old links will redirect, or if that...

How iBeacons Improve Business

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...

A week with CrossWorks

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.

I came...

How do I know where I should ask my question?

Nordic Semiconductor offer two gateways for asking questions about anything connected to their products, the MyPage support portal and Nordic Developer Zone. Questions in the support portal are only visible to, and answered by the application engineers in the Nordic Semiconductor’s support team. Questions in Nordic Developer Zone can be answered by anyone, the support team, other developers, and even yourself. Questions in the MyPage support portal are private, while in Nordic Developer Zone they are public.

Please search the Nordic Developer Zone before asking. Your question may be answered already. This gives you the answer faster, and limits...

nRF51 SDK v6.0.0 bug report and temporary workarounds

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.

Issues List

  1. [DeviceManager] Unable to re-connect to the second bonded central (Fixed in SDK v6.1)
  2. [DeviceManager] Unable to re-connect to a bonded central that uses Resolvable Private Address (e.g iOS device) if the application doesn't do whitelist advertising. (Fixed in SDK v6.1)
  3. [S310][BootLoader] S310 BLE bootloader doesn't work with Android and iOS...

Recover the nRF51 when nrjprog and nRFGo Studio couldn't

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:

Development with Eclipse and GCC

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...

CrossWorks CrossStudio examples

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/

Nordic nRF51 support in Em::Blocks (with softdevice integration)

Em::Blocks supports now the nRF51 devices from Nordic. You can select in the new project wizard which device family (51422 or 51822) and if soft devices are needed or not.

image description

The templates for the softdevices are empty after first installation. The packages must be downloaded from the Nordic download section (after login) and unpacked inside the wizard template sub directories. After the execution of the convSD.bat file there will be c-array files and API includes generated which can be used by the wizard.

The softdevices are placed at the right location by the linker so you don't...

Beacon Kit - Mistake in Ref_Design_UG_v1.0

I connected the programming header as described in "nRF6930_Beacon_Ref_Design_UG_v1.0.pdf" 5.5.4 Programming interface. I was trying to program Beacon Kit but failed many times then I compared it with schematic of of Beacon Kit. I found out that there is a mistake in the documentation. In P2 pin number 6 is not ground its actually P0.11 and pin number 5 is not P0.11 its ground.

Many of you must be facing this same problem.

I am attaching screen shot that will clearly indicate the mistake.image description(/attachment/e0adb43d9ba15501224dce2c643476ba)

Getting started with nRF51 development on Mac OS X

Update: Since this blog was originally written the nrfjprog tool has been ported to OS X (now macOS). This means that the flash programming is much simpler, and it is simply a matter of following the documentation for the tool. Also, nRF Toolbox for iOS is deprecated; use the nRF Connect iOS app instead


I recently decided to try the nRF51 SDK on Mac OS X to see how it was to compile and program the example applications. It worked nicely, and it wasn't even that hard to figure out. But evidently there were things to find out, and...

Motor Control over BLE with nRF51822 and TB6612FNG

In this project, we will control two motors over BLE using the Nordic nRF51-DK. To do this, we will use a motor driver based on the Toshiba TB6612FNG chip. We will use GPIOs and PWM to communicate with this board.
