Hi,
I am looking at the software ACK mechanism in CC2420. In
CC2420RadioM.nc, when a packet is received and if it requests an
ACK, the command strobe SACK is issued.
(in doRXFIFODoneBody
// if ack is requested, must pass CRC and match our address
if ((rxbufptr->fcfhi & (1 << CC2420_DEF_FCF_BIT_ACK)) &&
(rxbufptr->crc) &&
(rxbufptr->addr == TOS_LOCAL_ADDRESS)) {
call HPLChipcon.cmd(rh, CC2420_SACK);
}
)
And let's say that stateRadio is IDLE_STATE (before and after
receiving the packet).
Just to check: this is Boomerang, right, not TinyOS?
