Hi all,
I want to create a packet and each time that the packet is being created I want
to send it to a specific sensor board knowing the TOS_NODE_ID of the nodes.
I have 3 telosb boards. I assign node ids of 1,2 and 3 to them when uploading
the program. But for giving the address (switching between 2 addresses in
"AMSend.send()" method, the compiler gives some errors. Here is part of my code:
bool _radioBusy = FALSE;
message_t _packet;
uint16_t _address = 2;
event void Boot.booted()
{
call Notify.enable();
call AMControl.start();
}
event void Notify.notify(button_state_t val)
{
if(_radioBusy == FALSE)
{
if(_address == 2)
{
_address = 3;
}
else
{
_address = 2;
}
//Creating the packet
MoteToMoteMsg_t* msg = call Packet.getPayload(& _packet ,
sizeof(MoteToMoteMsg_t));
msg->NodeId = TOS_NODE_ID;
msg->Data = (uint8_t) val;
//Sending the packet
if(call AMSend.send(_address,& _packet , sizeof(MoteToMoteMsg_t)) == SUCCESS)
{
_radioBusy = TRUE;
}
}
}
And here is the error :
In file included from MoteToMoteAppC.nc:9:
In component `MoteToMoteC':
MoteToMoteC.nc: In function `Notify.notify':
MoteToMoteC.nc:56: syntax error before `*'
MoteToMoteC.nc:58: `msg' undeclared (first use in this function)
MoteToMoteC.nc:58: (Each undeclared identifier is reported only once
MoteToMoteC.nc:58: for each function it appears in.)
I found if I remove the if/else statement for checking for "_address" inside
the Notify event, the progam compiles...but then I will only be able to send to
node with ID of 2.
Can you please tell me how to solve this problem? I was following the guide
here on youtube: http://youtu.be/CBhVPXpTz_Q
Thanks,
Sean.
