Never explicitly tried it before with the intention of noting the results, but your node should transmit, leaving the RXFIFO turned to garbage and filtered out naturally by the receive methods (i.e. checking for a proper length byte and CRC). I could be wrong, but note that having two transmitters next to each other without using clear channel assessments leaves them both transmitting and rarely receiving clean packets.
If the length byte is within bounds, then the radio stack can safely download the packet and check the CRC byte regardless of what happened. If the length byte in the RX FIFO is not within bounds (smaller than expected, or larger than the RX FIFO size) then the RX FIFO certainly needs to be flushed. -David _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of roberto pagliari Sent: Tuesday, September 18, 2007 4:43 PM To: tinyos-help@Millennium.Berkeley.EDU Subject: [Tinyos-help] CC2420 packet delivery Hi All, does anyone know what happen if, during the receiption of a packet, a STXON (not STXONCCA) strobe command from the microcontroller is issued? Does the radiochip turn the circuit to the transmitter? If so, should I flush the RXFIFO queue? many thanks, Roberto
