what do you mean? packet is already global. here is the code:
module NodeC @safe()
{
uses interface Timer<TMilli> as Timer0;
uses interface Leds;
uses interface Boot;
uses interface Random;
uses interface ParameterInit<uint16_t> as SeedInit;
uses interface Receive;
uses interface AMSend;
uses interface SplitControl as AMControl;
uses interface Packet;
}
implementation
{
message_t packet;
uint16_t value;
uint16_t mybfr[50];
uint8_t idx;
bool locked;
event void Boot.booted()
{
call SeedInit.init( 2 );
idx = 0; locked = FALSE;
call Leds.led0Off(); call Leds.led1Off(); call Leds.led2Off();
value = (call Random.rand16()) % 8;
call Timer0.startOneShot( (call Random.rand32()) % 2048 + 100 );
/* if( (value & 1) == 1 ) {
call Leds.led0On();
}
if( (value & 2) == 1 )
call Leds.led1On();
else
call Leds.led1Off();
if( (value & 4) == 1 )
call Leds.led2On();
else
call Leds.led2Off();*/
}
event void AMControl.startDone(error_t err) {
if (err == SUCCESS) {
}
else {
call AMControl.start();
}
}
event void AMControl.stopDone(error_t err) {
// do nothing
}
event void Timer0.fired()
{
//dbg("BlinkC", "Timer 0 fired @ %s.\n", sim_time_string());
my_msg_t* rcm = (my_msg_t*)call Packet.getPayload(&packet,
sizeof(my_msg_t));
if (rcm == NULL) {
return;
}
// call Leds.led0Toggle();
rcm->color = value;
if (call AMSend.send(AM_BROADCAST_ADDR, &packet, sizeof(my_msg_t)) ==
FAIL) {
dbg("RadioCountToLedsC", "RadioCountToLedsC: packet sent.\n",
counter);
call Leds.led0Toggle();
locked = TRUE;
}
call Timer0.startOneShot( (call Random.rand32()) % 2048 + 100 );
}
event message_t* Receive.receive(message_t* bufPtr, void* payload, uint8_t
len) {
//dbg("RadioCountToLedsC", "Received packet of length %hhu.\n", len);
/*if (len != sizeof(radio_count_msg_t)) {return bufPtr;}
else {
radio_count_msg_t* rcm = (radio_count_msg_t*)payload;
if (rcm->counter & 0x1) {
call Leds.led0On();
}
else {
call Leds.led0Off();
}
if (rcm->counter & 0x2) {
call Leds.led1On();
}
else {
call Leds.led1Off();
}
if (rcm->counter & 0x4) {
call Leds.led2On();
}
else {
call Leds.led2Off();
}*/
call Leds.led1Toggle();
return bufPtr;
}
event void AMSend.sendDone(message_t* bufPtr, error_t error) {
if (&packet == bufPtr) {
locked = FALSE;
}
}
}
the send function always fails at the moment..
