The long weekend's haul is that, apart from some infrastructure work, I
got Y-Box to send something on its RF interface. For now, it's just a
constant wave, not useful data, but it's nice to see that the RF side
appears to be in good shape as well.
Pictures or it didn't happen ? Alright, alright, here it is, even with
By the way, I'm not sure what audio format works best with WebM. I
just used Vorbis. Does this work for the players that need WebM ?
Regarding future things to test, while I think I don't need to
implement full BTLE reception or transmission just now, there is one
detail that needs examining: the data sheet of the CC2543 is somewhat
vague on the RX-TX and TX-RX turn-around time. BTLE requires 150 us.
So I'll have to cook up some tests that let me measure these
turn-around times before I can be sure that the chip's RF circuit is
fast enough for BTLE.
