ANT and ANT+ on NRF52 boards #7310

I wish to be able to use ANT and ANT+ on NRF52 boards. I use it for implementing ANT+LEV EBike standard as also GPS cycling display Garmin Edge page change but in C, similar to Nordic SDK code, if anyone is interested: https://github.com/OpenSourceEBike/EV_Display_Bluetooth_Ant/tree/main/firmware/display/antplus_lev

We have not supported ANT and ANT+ because of the licensing fee requirements: https://www.thisisant.com/developer/components/view-all-components/nrf52-ant-stack-licensing-faq

When I was researching this a while ago, I found that some bike devices that support ANT+ also support BLE, such as the Wahoo sensors.

It is not completely clear to me if Adafruit would be required to pay the licensing fee, because we are selling boards that could load the ANT+-capable software, even if just for hobbyist use, or if the licensing fee is meant to apply only to commercial products that use ANT+.

Yes, the DIY EBike display I built have simultaneous Bluetooth and ANT+, it works very well: https://opensourceebike.github.io

But I would prefer to develop again that display based in Python code instead. And ANT+ is a MUST for cycling devices, from electronics gears shifters, tire pressure sensors and the EBike motors.
