I have a file called power2420.extra that has the following:

 

PFLAGS +=   -DCC2420_DEF_RFPOWER=15

 

Check out the CC2420 datasheet to see what values you can put for the power.

 

That way you can just do: make telosb power2420 bsl,auto and easily change
the power for future use.

TinyOS2.x

 

If that's what you need to do, it must be useful to have a look at the
archives. Both CC1000 and CC2420 allow you to set the transmitting power.

Thanks for you reply.

My aim is to reduce the transmitting range and I understand that this
can be done by reducing transmitting prower. So that is, i feel, the
second options you suggested.
