    Receive and read data in wireless mote communication

    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:
    Code:
    event TOS_MsgPtr ReceiveMsg.receive(TOS_MsgPtr msg){
    	call Leds.redToggle();
    	return msg;
    	}
    The struct of the packet is this:
    Code:
    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.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    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.
