[Tinyos-help] TOS_Msg size

[Bhavish Aggarwal]

Hi,

I've been trying to send a TOS_Msg struct over wires between 2 tmote
sky nodes. One thing I am not sure about is what is the size of
TOS_Msg packet that will be transmitted? I will be extremely thankful
for any help on this issue.

To transmit, I am doing the following:

typedef struct{
    uint8_t val;
}datanew;

TOS_MsgPtr msg;

body = (datanew*) msg->data;
body->val = 1;

packet = (uint8_t*) msg;
length = sizeof(msg);

while(length > 0){
      call UartControl.tx(packet[sendCount]);
      while (! call UartControl.isTxEmpty() ) ;
      length--;
      sendCount++;
}
