Hi All, I am currenting doing a very simple network test. I designed the message structure in ****.h file and some sending functions in the following.
typedef nx_struct HashMsg { nx_uint16_t nodeid; nx_uint8_t flag; nx_uint32_t payload_MD1; nx_uint32_t payload_MD2; nx_uint64_t payload_M; nx_uint64_t payload_R; nx_uint16_t payload_ID; } HashMsg; Part of the sending code is as folows: event void Timer0.fired() { uint16_t destinationMote=0x0002; if (!busy) { HashMsg* hmpkt = (HashMsg*)(call Packet.getPayload(&pkt, sizeof(HashMsg))); if (hmpkt == NULL) { return; } hmpkt->flag=1; hmpkt->nodeid = TOS_NODE_ID; hmpkt->payload_MD1 = 0x12345678; hmpkt->payload_MD2 = 0x90ABCDEF; // disable this line, it will work hmpkt->payload_M=0x0000000000000000; hmpkt->payload_R=0x0000000000000000; hmpkt->payload_ID=0x0000000000000000; if (call AMSend.send(destinationMote, &pkt, sizeof(HashMsg)) == SUCCESS) { call Leds.led0On(); busy = TRUE; } } } When the program loads the data to send. The program is dead with one more line "hmpkt->payload_MD2 = 0x90ABCDEF";. I don't know what the problem is as I have changed the #define TOSH_DATA_LENGTH to 35 in message.h which is enough to handle the data. However it didn't work still. I suspect that it could be message size problem. But I can't work it out. THanks. Regards, Bai
