Using multiple UARTs on nRF9160dk

[Jagruti]

Hello,

I am using UART_1 in my program to comminicate with other sensor. So the data is read from UART_1 and print to UART_0. Now I want to communicate with other sensor simultaneously. So I am using UART_2 for that purpose. When I connect both sensors to UART_1 and UART_2, only the data from UART_1 is read and it is printed on the terminal. But the data from UART_2 is not read and printed. So how to read and print the data from both UART on the terminal at the same time.

The Code is:

}

void uart_cb1(struct device *x1)

void main(void)
{
	struct device *uart = device_get_binding("UART_2");
    struct device *uart1 = device_get_binding("UART_1");

	uart_irq_callback_set(uart, uart_cb);
	uart_irq_rx_enable(uart);
        uart_irq_callback_set(uart1, uart_cb1);
	uart_irq_rx_enable(uart1);
	printk("UART loopback start!\n");
	while (1) {
		k_cpu_idle();
	}
}

Is this code correct or is there any other way to use 2 UARTS simultaneously?
