Hello,

the best thing I can think of at the moment is the lpuart sample, located at nrf/samples/peripheral. I have a modified version of this sample that uses regular UART. It's a bit old, but if you want to have something to start with I can send you that.

    please send me your reference sample ！！

There you go. I made overlays for both the nrf9160 SiP and nrf52840 SiP on the DK. If you want to test you can just build and flash for the respective boards, and you should be able to see data on both the nrf52840 and nrf9160. If anything is missing or not working properly, just let me know.
