https://devzone.nordicsemi.com/f/nordic-q-a/81502/can-t-use-uart2-in-nrf9160-when-update-sdk-1-6-0Hi. I used sdk 1.4.0 with nrf9160, I used UART2 to comunicate with another mcu. I run fine and no problem. Today, I update to SDK 1.6.0, I edited UART2 ( in device tree), but it can&#39;t receive any data from uart 2 ( but uart 1 still run fine).
