I would really like to see somebody clear things up for me:
In the CC2420 datasheet it says, that you can switch from "All RX states" to TX_CALIBRATE issuing a STXON of STXONCCA.
What happens if the CC2420 is in state RX_FRAME e.g. and I call STXON?
Is the frame I am reciving at the moment lost?
Or is the CC2420 always first receiving the frame and then switching to TX-mode?
There is also this strange thing in the state machine with the SACK command strobe.
It looks like the state is switched directly after SFD is detected to TX_ACK_CALIBRATE.
But the ACK has to know the Sequence number of the frame.
And it should not stop the reception of the current frame.
If somebody could clear this up for me, this would be great.
At the moment I am thinking about if TinyOS might be dropping frames because of this.
But I think this can't be the case, so that's why I am asking this here.
Thanks in advance
