Use of the embedded ANT protocol on devices such as Nordic Semiconductor’s nRF24AP2 and TI’s CC257x, and the related modules in a design does not require a license.
If you are building a non-ANT+ product (i.e. an ANT product that does not implement an ANT+ Device Profile) you may not use the ANT+ network key or the ANT+ frequency (2457MHz). You may use any other frequency and either the public network key or a private network key.
If you are building a product that is intended to interoperate with other ANT+ devices or applications, you’ll find our ANT+ Device Profiles, and an array of design tools, on the downloads page. Items marked with the ANT+ logo are only accessible to ANT+ Adopters. You can access them by signing up (for free!) to become an ANT+ Adopter, here: ANT+ Adopter sign-up. This will also give you access to a lot of good ANT+ forum advice, and the ANT+ network key.
To participate in the development of new ANT+ device profiles, gain direct technical support, and participate in B2B opportunities such as the ANT+ Symposium; see ANT+ Alliance Membership.
Openly available software posted on our downloads page comes with the Apache 2.0 license or the FIT protocol license. We’d like you to use the code, recognizing the value of maintaining interoperability.
Software marked with an ANT+ icon; (and only accessible to ANT+ Adopters) is covered by the ANT+ shared source license. Please check this for details and restrictions, however in general you are free to use the reference code within your commercial ANT+ products.
With some System on Chip (SoC) devices, the ANT protocol stack is not embedded on the device, and is accessed as a downloadable software component by the developer who is using the SoC.
For the Nordic Semiconductor nRF51 Series SoC device, the ANT capable protocol stacks are accessed with a click through agreement from Nordic’s website.
ANT protocol stacks for the Nordic Semiconductor nRF52 Series SoC devices are licensed by ANT Wireless for evaluation and for commercial or other revenue generating purposes under two separate agreements. Use of the ANT stacks for evaluation purposes only is free. There is a per-instance royalty fee associated with use of the ANT stacks for revenue-generating purposes. Please see the nRF52832 component page and the FAQ (basic user account login required) for more information on the click through licenses associated with these protocol stacks.
