Hello,
I am Victor Rosello, i am trying to send a command to a base station
using the serial port and transmit this message using the radio.
After some test I realize that if I have SerailActiveMessageComponentC
and ActiveMessageComponentC running at the same time using the
SplicControlC.start() the base station does not get the serial port
messages. I am using a telosb-like mote.
To reproduce the failure I modified the TestSerial application. as follows.
I don`t know how to dela with this problem, to use the
ActiveMessageComponentC to use radio communications and
SerailActiveMessageComponentC to use the serial port at the same time.
