Hi Lyubomir,
Please, could you explain further what you mean with sending more than
one packet at a time? I am sure to be missing something, otherwise
could it be as simple as to make a for-loop?
For setting the power I am only familiar with the CC2420 radio. In
such a case you only have to load the right module.
In your config file...
// Receiver calibration
typedef nx_struct SerialRxMsg {
nx_uint8_t id;
nx_uint8_t rssi;
} SerialRxMsg;
In your module...
module CalTxC{
uses {
interface SplitControl as RadioSplitControl;
interface SplitControl as SerialSplitControl;
interface CC2420Packet as RadioPacket;
.... etc...
}
implementation {
RadioMsg * pointerRadio;
SerialTxMsg * pointerSerial;
event void RadioSplitControl.startDone(error_t error){
if (error != SUCCESS) {
call Leds.set(6);
call RadioSplitControl.start();
}
else {
call SerialSplitControl.start();
}
}
event void SerialSplitControl.startDone(error_t error){
if (error != SUCCESS) {
call Leds.set(7);
call SerialSplitControl.start();
}
else {
call Leds.set(0);
pointerRadio = call
RadioAMSend.getPayload(&pkt, (uint8_t) NULL);
call Timer.startPeriodic(PERIOD_0);
}
}
event message_t * SerialReceive.receive(message_t *msg, void
*payload, uint8_t len){
call Leds.set(7);
pointerRadio = (RadioMsg*) payload;
call RadioPacket.setPower(&pkt ,pointerSerial->rssi);
return msg;
}
}
In your configuration...
implementation {
components ActiveMessageC;
components new AMSenderC (AM_RADIOMSG);
components CC2420PacketC;
components SerialActiveMessageC;
components new SerialAMReceiverC (AM_SERIALTXMSG);
... etc ....
}
I assume you know the rest :-)
Cheers!!
Sergio
