Hello!
I am trying to make a node send a data packet to another node, but i cannot
figure out how i can achieve this..
For example, I have created a struct:
typedef nx_struct msg_send_temp {
uint8_t msg_type;
uint8_t temp
} msg_send_temp_t;
I try to send it with the help of Packet, and AMSend interfaces like this:
void msg_send_temp(am_addr_t XXXXX) {
msg_send_temp_t* pkt = (msg_send_temp_t*)call Packet.getPayload(&packet,
sizeof(msg_send_temp_t));
if(pkt == NULL){
return;
}
pkt->msg_type = (uint8_t)SEND_TEMP_MSG;
pkt->temp = node_temp;
call AMSend.send(XXXXX, &packet, sizeof(msg_send_temp_t));
dbg("NodeC","Temp information sent, node id = %hu.\n", node_id);
return;
}
The XXXXX written above, is supposed to be an am_addr_t of the other node,
whose am_addr_t needs to be taken from a Receive function like this:
event message_t * Receive.receive(message_t * msg, void * payload, uint8_t
len){
if(len == sizeof(msg_request_temp_t)){
msg_request_temp_t* pkt = (msg_request_temp_t*)payload;
if (pkt->msg_type == REQUEST_IS_HEAD_MSG){
msg_send_temp(XXXXX); //Here i should try to get the msg's am_addr_t..
}
return msg;
}
However, i cannot figure out how to take the address of the source node, to
correctly pass it to the msg_send_temp(am_addr_t) function..
Can i use simultaneously both the AMPacket and the Packet interface?
Thank you in advance for your time,
