[Tinyos-help] Changing radio channel on IRIS and MicaZ

[Miklos Maroti]

Hi Andrey,

I have added a RadioConfig interface through which you can change the
channel. You might need to power down the radio stack through
SplitControl if you want to avoid the rare cases when you cannot
change the channel because the stack is currently transmitting or
receiving messages. All interfaces are exported from
RF230ActiveMessageC. You need to download the latest CVS version.

Best,
Miklos
