What is the function of this code atomic{ packet_type = DATA;//Data //lenght as seen by the receiver: sent data + crc msg_ptr->length = msg_ptr->length + MSG_HEADER_SIZE + MSG_FOOTER_SIZE; // put default FCF values msg_ptr->fcflo = CC2420_DEF_FCF_LO; msg_ptr->fcfhi = CC2420_DEF_FCF_HI; // keep the DSN increasing for ACK recognition msg_ptr->dsn = ++currentDSN; // destination PAN is broadcast msg_ptr->destpan = TOS_BCAST_ADDR; // adjust the destination address to be in the right byte order msg_ptr->addr = toLSB16(msg_ptr->addr); ////// the following fields are not actually received ////// // reset the time field msg_ptr->time = 0; } With regards Sivasankar
