Bluetooth low energy

Bluetooth low energy is a global standard that enables short range communication between devices using minimal power. It makes it possible to make applications that can run for months, even years on a single coin cell battery.

Your device must meet Bluetooth SIG standards and must be a qualified product before being marketed as a Bluetooth product. See the Product certification section for more information.


Geared for communicating with sensors, ANT is most commonly used in the fitness industry and can be found in smart watches, fitness equipment, and fitness monitors.

You must qualify your device as an ANT authorized product. See the Product certification section for more information.


In addition to ANT and Bluetooth, our nRF5 Series of SoCs support any proprietary protocols that also operate in the 2.4 GHz range. Choose Proprietary if you want:


802.15.4 MAC is used to build a proprietary network or to act as a basis for a variety of different higher layer standards including Thread, ZigBee, Wireless HART, RF4CE, ISA100.11a, and 6LoWPAN.


Our nRF5 Series SoCs are capable of running multiple protocols at the same time, allowing you to communicate with a broad range of devices within the 2.4 GHz range. Choose Concurrency if you want:

A SoftDevice that combines Bluetooth and ANT is the S332 SoftDevice for the nRF52 Series and the S310 SoftDevice for the nRF51 Series.
