Currently changing the channel dynamically is not supported. The
easiest way to do that would be to modify the
async command uint8_t RF230Config.getDefaultChannel()
{
return RF230_DEF_CHANNEL;
}
command in the RF230ActiveMessageP.nc file to return the channel
dynamically. Then to change the channel you need to stop the
RF230ActiveMessage component with SplitControl and then restart it.
Note, it is not practical to set this on a per packet basis since on
the receiver side the node cannot listen on multiple channels
symultaneously.

It is define in tinyos-2.x\tos\platforms\iris\chips\rf230\HplRF230.h
