ANT Wireless Networks
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 any 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. Note that these materials and use of the ANT+ network key is subject to the ANT+ Adopter Agreement.
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 is subject to 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 most 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.
ANT softdevices and stacks for Nordic Semiconductor SoC devices are licensed by Garmin for evaluation and for commercial or other revenue generating purposes under 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 softdevices and stacks for revenue-generating purposes. Please see the nRF Connect SDK page for more information on the available ANT Stacks for compatible Nordic Semiconductor devices. Please see the nRF5 SDK page for more information on legacy ANT softdevices for Nordic Semiconductor's nRF52 SoC devices.
