RE: Using the UART2 with MQTT client

Hi,

What are the errors/behavior you're seeing?

Try enabling "uart2" in DTS, by adding a overlay file (should be located in the "boards" folder of your application, create the folder if not already present):

&uart2 {
    status = "okay";
};

For the DK, the filename and path should be:

boards/nrf9160dk_nrf9160_ns.overlay

Kind regards,

Håkon

Refer interrupt_handler() function given in the sample - zephyr/samples/subsys/usb/cdc_acm/src/main.c
