[Tinyos-help] SimpleCmdMsg format

[jabdo]

Hi,

I have a question concerning the format of the SimpleCmdMsg found in
C:\tinyos\cygwin\opt\tinyos-1.x\apps\simpleCmd...In SimpleCmdMsg.h,
"typedef struct {
    int nsamples;
    uint32_t interval;
} start_sense_args;

typedef struct {
    uint16_t destaddr;
} read_log_args;

// SimpleCmd message structure
typedef struct SimpleCmdMsg {
    int8_t seqno;.....0
    int8_t action;....1
    uint16_t source;...00
    uint8_t hop_count;...0
    union {
      start_sense_args ss_args;...0 0000
      read_log_args rl_args;...00
      uint8_t untyped_args[0];..0
    } args;
} SimpleCmdMsg;"

So if the command is LED_ON, We should have: 0 1 00 0 0 0000 00 0 but
after running the BcastInject code found in
tinyos\cygwin\opt\tinyos-1.x\tools\java\net\tinyos\tools...It just shows:
sending payload: 0 1 0 0 0 0 0 0 0 0 0 (9 zeros after the one...and it
should be 11 zeros)..

Am I right in analyzing the payload for the LED_ON commad????

Thanks in advance,

Julia.
