So, is that the recommended number of preamble bits for 300kbps? 4 bytes worth? I seem to be getting pretty good results with just one byte of preamble.
It sounds like one rounds up from the desired number of bits to the nearest number of bytes? For instance, if the DS says the preamble is 12 bits (which is obviously not an even multiple of 8-bit bytes), then when setting the preamble length, do I need to make it 2 bytes? That part I'm still unclear about.
