Receive and read data in wireless mote communication

[Sigmar]

Hi, I'm doing a project in which interchange packets between sensors, but I don't know how I can take the data from a packet with the interface ReceiveMsg.

I get the package so:

event TOS_MsgPtr ReceiveMsg.receive(TOS_MsgPtr msg){
	call Leds.redToggle();
	return msg;
	}

The struct of the packet is this:

typedef struct XSensorHeader{
  uint8_t  board_id;
  uint8_t  packet_id; // 3
  uint8_t  node_id;
  uint8_t  rsvd;
}__attribute__ ((packed)) XSensorHeader;

typedef struct PData1 {
  uint16_t vref;
  uint16_t thermistor;
  uint16_t light;
  uint16_t mic;
  uint16_t accelX;
  uint16_t accelY;
  uint16_t magX;
  uint16_t magY;
  uint16_t constante;
  } __attribute__ ((packed)) PData1;

typedef struct XDataMsg {
  XSensorHeader xSensorHeader;
  union {
  PData1    datap1;
  }xData;
} __attribute__ ((packed)) XDataMsg;

I have to do, for example, if I want take the data of light of the message I get.

Thanks.

Huh?

> call Leds.redToggle();
This isn't even valid C or C++ code.

What kind of interface (USB/Ethernet/Other)

What is at each end - PC / target board (state make/model).

What compilers are you using? What operating system(s) are involved.

I use nesC for TinyOS platform. TinyOS is an operating environment designed to run on embedded devices used in distributed Wireless Sensor Networks. nesC is built as an extension to the C programming language with components "wired" together to run applications on TinyOS.

I use IRIS motes for the wireless sensor network.

I use the compiler Programmers Notepad 2. And Windows XP operating system.



I hope this clarifies your questions.
