Serial library event handler example

[SRose]

Hi,

Does anyone have a complete example of using an event handler to read UART data set up with the serial library? This post is the only incomplete example I can find. The example program sets _ev_handler to NULL in the setup NRF_SERIAL_CONFIG_DEF

OR my devices needs to constantly read continuous incoming UART data, so does someone have the best practice on reading the serial so the buffer doesn't overflow? Thanks

This works in SDK 15:

static void serial_rx_cb(struct nrf_serial_s const *p_serial, nrf_serial_event_t event) {
    if (event == NRF_SERIAL_EVENT_RX_DATA) {
        char c;
        APP_ERROR_CHECK(nrf_serial_read(&serial_uart, &c, sizeof(c), NULL, 500));
        APP_ERROR_CHECK(nrf_serial_write(&serial_uart, &c, sizeof(c), NULL, 500));
        //__LOG(LOG_SRC_APP, LOG_LEVEL_INFO, "%c\n", c);
    }
}

But it is still char by char. I don't know how to use it properly with a bigger SERIAL_BUFF_RX_SIZE?
