Enabling uart 1 on nrf52dk?

[suadsuljic7]

Hi I m trying to use uart 1 on nrf52dk pca10056. In the syscfg.yml i add syscfg.vals: UART_1: 1 UART_1_PIN_TX: 15 UART_1_PIN_RX: 14 UART_1_PIN_RTS: 5 UART_1_PIN_CTS: 7 and I'm using the hal_uart_blocking_tx() function to send the data. But I receive nothing on the serial.

With syscfg that you have try this code:

    struct uart_conf uc = {
            .uc_speed = 115200,
            .uc_databits = 8,
            .uc_stopbits = 1,
            .uc_parity = UART_PARITY_NONE,
            .uc_flow_ctl = UART_FLOW_CTL_NONE,
            .uc_tx_char = NULL,
            .uc_rx_char = NULL,
    };
    struct uart_dev *uart = uart_open("uart1", &uc);
    uart_blocking_tx(uart, 'h');

using hal_uart_blocking_tx() requires more configuration that is done here partially by syscfg UART_1: 1 and by uart_open()
