Nordic nRF51¶

Configuration:: platform = nordicnrf51

The Nordic nRF51 Series is a family of highly flexible, multi-protocol, system-on-chip (SoC) devices for ultra-low power wireless applications. nRF51 Series devices support a range of protocol stacks including Bluetooth Smart (previously called Bluetooth low energy), ANT and proprietary 2.4GHz protocols such as Gazell.

For more detailed information please visit vendor site.

Examples ¶

Examples are listed from Nordic nRF51 development platform repository:

Debugging ¶

Debugging - “1-click” solution for debugging with a zero configuration.

Tools & Debug Probes ¶

Supported debugging tools are listed in “Debug” column. For more detailed information, please scroll table by horizontal. You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions.

On-Board Debug Tools ¶

Boards listed below have on-board debug probe and ARE READY for debugging! You do not need to use/buy external debug probe.
