Thanks Kenneth - I will give this a try.

I am not aware of anything ready made here.

I suggest to include libuarte to handle the serial transfer on the nRF52840, you would need to define a set of commands you may wish to configure the ANT channels from the nRF9160, and then the nRF52840 would simply forward the ANT data to the serial interface every message period.

Thanks Kenneth.

I have built the ant+/rx component of the code (with the SDK) and its working fine (testing on a 52840DK).

What would the best way to get this (ant+) data from the nrf9160dk_52840 to the nrf9160dk_9160. Thats where I was hoping a simple UART component could work, just like a serial type connection, or is there a better way to get comms between the 2 chips ? Any examples to do a data transfer between the these chips.

I looked at the nrf9160dk_9160/lte_ble_gateway as an example, but wasnt sure on the UART connection from the nrf9160dk_52840 - specifically if there was an example from the nRF SDK I could use that would work.

The goal is to run this all on a Thingy91 - so I want to make sure the project will actually work...

Hi,

There is no ANT or ANT+ support in zephyr, so you need to use the legacy nRF5 SDK if you want to develop an ANT or ANT+ application:
