ANT
The ANT advantage
Flexible and simple to use
Good choice for small, battery-operated devices
ANT is a popular proprietary ultra-low power wireless solution operating in the 2.4 GHz ISM band that is especially suited for battery operated products. Its outstanding power efficiency has seen it become a popular choice for wireless applications in the fields of sports and fitness, and health and wellness.
Lightweight protocol with interoperability
The easy to use lightweight protocol helps developers make and implement wireless products with a small memory footprint. The ANT+ managed network gives vendors product interoperability, including a broad set of application-specific profiles allowing products to exchange data and work together. A number of Android devices have native ANT support.

Nordic development tools
Nordic offers a range of thoroughly tested software and development tools to ease your ANT and ANT/Bluetooth development projects.
From our SoftDevices that offer pre-compiled binaries without run-time dependencies to our SDK with hundreds of useful firmware modules, we’ve got you covered.
SoftDevices
Protocol stacks supporting ANT/Bluetooth LE development
Nordic SoftDevices are protocol stacks that are pre-compiled binaries without run-time dependencies.
Developers can design their application interactions with the SoftDevice for predictable and reliable operation.
SoftDevices are complete and qualified when we deliver them, they are unaffected by the ‘develop and compile’ cycle of application development and always remain stable.
Nordic nRF52 and nRF51 Series support ANT and ANT/Bluetooth LE SoftDevices.
ANT/Bluetooth LE SoftDevices offer concurrent operation between protocols.
