Renable CDC drivers CDCEnable.term
I've installed version 4.69b on MBP, runs well, remember only to disable CDC using Segger Mac OSX CDCDisable bash script.
I will download the J-Link software for Mac from here.
Followed the instructions in nAN-29 to set up the debugging. In the "GDB command" field of the Debug Configurations dialog, I used the Browse button to find the arm-none-eabi-gdb binary. This way I don't have to set up any paths.
I start the gdb server using the terminal from the /Application/SEGGER directory, using the following command line:

Nordic offers a range of HW and SW tools you can leverage to get you started evaluating and developing applications on your chosen nRF51 Series device. Please use the links below to learn more about the development tools and software that are available from Nordic and 3rd parties.
Nordic Hardware&The nRF51 Series development hardware is provided by the nRF51 DK development kit and the nRF51 Dongle. The nRF51 DK and nRF51 Dongle covers the nRF51822 and nRF51422 SoCs and supports Bluetooth Smart, ANT and 2.4GHz proprietary SW development. In addition you may download the recommended nRF51 reference layouts from the download tab on this page.&nRF51 DK
For more information and relevant downloads, check out the .&nRF51 Dongle
For more information and relevant downloads, check out the &Reference layoutsSince the nRF51 Series devices all are SoCs for wireless communication, the quality of the PCB layout is of outmost importance to ensure good radio performance. Official nRF51 reference layouts can be found on the download tab of this page, and please do follow them closely to avoid dissapointments when testing or qualifying your product.
3rd Party Hardware&A number of 3rd party companies have made both complementary components as well as HW solutions based on nRF51 Series devices. Utilising these products may simplify your nRF51 development as well as production.&3rd Party Board

&3rd Party ModulesYou may find a wide range of pre-qualified modules based on nRF51 Series devices on our
if you don't want to spend time on the Radio design work and NRE costs to qualify a design for Bluetooth Smart and teleregulatory authorities (FCC, ETESI, MIC, TELEC).&
SOFTWARE&By using nRF51 Series devices you get free access to pre-qualified Bluetooth Smart as well as ANT protocol stacks for use in your applications along with extensive libraries and application examples.The software are split in two major parts: SoftDevices containing wire and the nRF51 Software Development Kit (SDK) forming a common application code base for all nRF51 devices.&
SoftDevicesA SoftDevice is precompiled and linked binary software, implementing a wireless protocol. While it is software, you as an application developer have minimal compile-time dependence on its features. The unique hardware and software support framework, in which it executes, provides run-time isolation and determinism in its behavior. These characteristics make the interface comparable to a hardware peripheral abstraction with a functional, programmatic interface.The SoftDevice Application Program Interface (API) is available to applications as a high-level programming language interface, for example, a C header file.Please find documentation as well as all available Softdevices, for free download, on the download tab of this page.
nRF51 SDKThe nRF51 Software Development Kit (SDK) is your starting point for software development on the nRF51 Series. It contains source code libraries and example applications covering :
Wireless as well as application examples
Bluetooth Smart and ANT+ profiles
Nordic’s 2.4GHz proprietary stack Gazell
Libraries for all nRF51 peripherals
Bootloaders
Wired as well as Over the Air (OTA) FW upgrades
Selected RTOS examples
Serialization libraries of Nordic SoftDevices
& The nRF51 SDK is built on the ARM(R) CMSIS standard and supports the following SW development tool chains:
&nRF51 SDK is available on the download tab of this page. &
Tools&In order to aid your product development with programming and test/debug, Nordic also offers a range of tools enabling you to interact with and monitor prototype/product:
nRFgo Studio
PC tool allowing device programming and Radio performance tests on nRF51.
Master Control Panel
An peer device emulator that allows you to connect to, monitor and interact directly with the bluetooth services in your product. This is a great tool to check if your product identifies itself and its capabilities the correct way as well as testing how it responds to correct as well as incorrect actions in the peer device.MCP is an application for Windows PC’s (using the nRF51-Dongle).
nRF Master Control Panel
A powerful generic tool that allows you to scan and explore your Bluetooth Smart devices and communicate with them. nRF MCP is an application on Android.
A peer device emulator for the ANT protocol running on PC’s with the nRF51-Dongle. This is a great tool to check if your product identifies itself and its capabilities the correct way as well as how it responds to correct as well as incorrect actions in the peer device.
nRF Sniffer
If the communication with a 3 party Bluetooth Smart Ready peer doesn’t work as intended, the nRF Sniffer enables you to monitor all the on air traffic between you and the peer through link establishment, security negotiations to exchange of data. Often the only way to find where communication breaks down, and logs from this tool will often be the first thing our support engineers will ask for if you enter a support case/request on MyPage regarding communication problems.
nRF51-BLE-Driver
Windows dll linking the MCP with the nRF51 Dongle. Presents an API similar to our SoftDevices for a PC application, making it ideal to make your own PC based test and demo tools.
nRFjprog (part of nRF51 toolset installer)
Command line utility enabling programming of nRF51 devices through Jlink programmers/debuggers.
Mergehex (part of nRF51 toolset installer)
Since the Nordic SoftDevices comes as precompiled hex files, when adding your own application, you will have (at least) 2 hex files to program into an nRF51 in your production line. Some industrial programmers can’t handle this and mergehex is a command line utility enabling you to combine multiple hex files into one for these programmers.
JlinkARM (part of nRF51 toolset installer)
Driver for jlink debuggers
Please find these tools on the download tab of this page. &
Mobile Apps&Your products are of course likely to communicate with a mobile device or computer, indeed that may be the sole purpose of it. To enable this you will need to interact with the wireless stacks and features in the installed OS’s themselves or an APP installed on top of these OS’s. To facilitate this part of the development, Nordic has a range of application examples and tools for all the main mobile operating systems. Please visit our
to get started with your mobile device SW development. &Legacy nRF51 development tools:Not recommended for new designs.
