I have purchased two nRF52833 development kits and I would like to implement Direction Finding using AoA method. I have purchased the uBlox ANT-B10 patch antenna board for the receiver side. The antenna board sends out direction data using UART. I would like to receive the data from the antenna board to a nRF52833 development kit using UART. I was looking at samples in the SDK v2.6.99 and I was unable to find any simple UART transmission procedure. Can anyone tell me the procedure to configure UART and perform UART Rx and Tx in the nRF5 2833DK?
