The default mode for the radio is Rx mode - after it transmits a packet, it automatically switches back to Rx on the hardware.
If you attempt to transmit using STXON without clear channel assessments, then your radio will not only *not* receive the other transmitter's packet, but it will cause channel interference that will prevent all other motes in the area from receiving that packet. That's the point of backoffs and CCA (clear channel assessment) - determine if the channel is clear before attempting a transmission. -David _____ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of roberto pagliari Sent: Tuesday, June 19, 2007 3:24 PM To: [email protected] Subject: [Tinyos-help] about CC2420 hi all, within RadioControlM I can see CC2420Control.RxMode(), but, after a packet has been sent I cant find any call to CC2420.RxMode() or SXON oscillator. where is it done? the second question is: once the transmitter oscillator STXON has been enabled, if an incoming message arrives, will it be lost? thank you
