Serial library mode selection

[nrbrook]

I'm using the serial library for the first time. What are the advantages/disadvantages of using IRQ and DMA? How should FIFO queue and buffer sizes be chosen?

[nrbrook]

The serial comm is not over BLE, it is with another micro, using the MIN protocol. That example just receives one character at once as your other examples do.

In this scenario, is using IRQ effectively the same as using DMA?

Yes, it is essentially the same under this situation.
