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

The event handler will be called on every NRF_DRV_UART_EVT_RX_DONE event from the UART driver. This will either happen when the number of bytes passed to the size parameter of nrf_serial_read() have been received, or when the timeout have been reached.

I am afraid that the  event handler will be called on every single byte received by the UART. No matter the "nrf_serial_read" parameters.

Could you kindly share with us an example use event handler for receive more than one byte?
