nrf_serial_read with DMA example

[wassfila]

usage of read always triggers an event after 2 characters,

In some rough tracking I noted that the EasyDMA RX.MAXCNT is configured on the call of the read itself, is that configuration permanent ?
Why do a call to read on init fails

[wassfila]

the serial read will be set to blocking, the DMA is using few bytes, not much helpful, but blocking serial would require less memory by fifoing the radio packets which are binaries, not text like the uart
