Hello,

I'm devloping Native App in Gear S3 and using socket to transfer file to Server.

But, some problem happend. When i use recv() function, the process has closed.

and this is my log message.

my code is like this.

static void
send_audio(appdata_s *data){

    appdata_s *ad = data;
 FILE *fp;
 struct sockaddr_in address;
 char buf[1024];
 char buff_audio[1024];
 char buff_rcv[1024];
 unsigned int file_size;
 int sendBytes;

 fp = fopen(ad->file_path,"rb");
 if(fp == NULL)
 {
  dlog_print(DLOG_ERROR,"USR_TAG","FILE Pointer ERROR");
 }

 fseek(fp, 0L, SEEK_END);
 file_size = ftell(fp);
 fseek(fp, 0L, SEEK_SET);

 int SendNum = file_size/sizeof(buff_audio)+1;
 dlog_print(DLOG_INFO,"USR_TAG","file Size: %d",file_size);

 memset(&address,0,sizeof(address));
 address.sin_family = AF_INET;
 address.sin_addr.s_addr = 274187880;
 address.sin_port = htons(8001);

 int sockfd = socket(AF_INET, SOCK_STREAM, 0);

 if(sockfd == -1) {
  dlog_print(DLOG_INFO,"USR_TAG","socket create fail");
  return;
 }

 if(connect(sockfd, (struct sockaddr*)&address, sizeof(address)) == -1){
  dlog_print(DLOG_INFO,"USR_TAG","socket connection fail");
  return;
 }

 //send Start Message
 if(send(sockfd,"TIZEN\n",6,MSG_NOSIGNAL)<=0){
  dlog_print(DLOG_INFO,"USR_TAG","write 1 error");
 }


 //file send
 /*
 while((sendBytes = fread(buff_audio,sizeof(char),sizeof(buff_audio),fp))>0){
   send(sockfd,buff_audio,sendBytes,0);
   dlog_print(DLOG_INFO,"USR_TAG","sendBytes:%d",sendBytes);
 }*/

 memset(buff_rcv, 0x00, 1024);
 if(recv(sockfd,buff_rcv,sizeof(buff_rcv),MSG_NOSIGNAL)==-1){
  dlog_print(DLOG_INFO,"USR_TAG","read 1 error");
 }
 dlog_print(DLOG_INFO,"USR_TAG","recv:%s",buff_rcv);
 close(sockfd);
}

When i delete the recv() function, the process is not closed.

I don't know why the recv function is not working and kill the process.

Plus, I upload my Server's python code's some part.

   elif (data == "TIZEN") | (data == "TIZEN\n"):

        wave_output_filename = ("%s" % (addr,))
        f=open(wave_output_filename+'.wav', 'wb')

        print ("start form tizen...")

        data = sock.recv(BUFSIZE)
        print "filesize:%s" %data

        """
        while (True):
            data = sock.recv(BUFSIZE)
            if (data == "END") | (data == "END\n"):
                print 'END'
                break
            else:
                f.write(data)
                print ('receive data, size: %s' % (len(data),))         
        
        """

        sock.send('ACK: TIZEN')
        print 'ACK: TIZEN'

        f.close()

When i start the Server code and Tizen code, the server console print "start from tizen.." and "ACK:TIZEN" correctly but the TIZEN code not receive the ACK and process dead...

Why this error occur? Using socket in tizen is not working?

I already added a privilege for internet..

Please help me, Thanks in advance.
