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 byte data coming in is a proprietary protocol. I need to store the data in a big buffer and search for the start / end bytes for each message and then parse the message. I do have a timing requirement. Once I receive the end byte for a given message, the program needs to respond by sending a msg on the serial within 300us - 6.0ms. It seems to me using the event handler is better for this than always querying the serial queue with a timer?
