   I don't think that this solution is very good, doing this kind of allocation and copy can be quite wasteful depending on message size. I think it is possible to do this by using "list mode" DMA (see SPI implementation on how this is used to transfer arbitrarily sized data in chunks, as one large transaction). For reference see p309 of nRF52832 PS.
