Hi everyone,
In CC2420 stack, channel switch can done through *
CC2420ControlP$CC2420Config$setChannel() *and then* **
CC2420ControlP$CC2420Config$sync()**, *which goes to the following event:
* event void SyncResource.granted() {
** call CSN.clr();
** call SRFOFF.strobe();
** writeFsctrl();
** writeMdmctrl0();
** writeId();
** call CSN.set();
** call CSN.clr();
** call SRXON.strobe();
** call CSN.set();
** call SyncResource.release();
** post syncDone();
** }*
Can anyone please give me some hint why SRFOFF and SRXON strobes are
necessary here? Thanks.
