Hi!
Use the latest CVS version of tinyos-2.x. Write an application that
continuously transmit messages. Then add these lines to your makefile:
CFLAGS += -DRF230_BACKOFF_MIN=100
CFLAGS += -DRF230_BACKOFF_INIT=100
CFLAGS += -DRF230_BACKOFF_CONG=100
Then copy RF230DriverLayerP.nc into your application directory, and
comment out these lines:
if( call Config.requiresRssiCca(msg)
&& (readRegister(RF230_PHY_RSSI) &
RF230_RSSI_MASK) > ((rssiClear
+ rssiBusy) >> 3) )
return EBUSY;
from the RadioSend.send command.
This should give a pretty good jamming singnal :) If it is too good,
then increase the BACKOFF values (those are in microseconds).
Best,
Miklos
