nrf9160 uart1

[nicekey]

Hi，I have a question:

1.I use device_ get_ Binding ("UART_1") When UART1 is opened, ENXIO returns to 134. How do you solve this problem? For others, I used uart0, spi2, spi3.

Hi,

The UART driver has three different API types as noted in the documentation here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.1.0/zephyr/hardware/peripherals/uart.html, and if you try to use an API type that has not been enabled (see config settings here), then it will return with -134 / (-ENOTSUP).

Could you let me know the function that returns ENOTSUP?

Best regards,

Vidar
