Hi, i am working on lwip ppp over serial using gsm.I am successfully able to post to my web server.but
1)On calling lwip_read(s, Get_Post_Buffer_GSM, PPP_BUF_SIZE),it calls the netconn_recv_data function,there is a call to sys_arch_mbox_fetch(&conn->recvmbox, &buf, 0);on line 427 in api_lib.c.when the function sys_arch.... returns the value inside the buf is zero 2)on the lower side the function call sio_read succesfully reads the expected string and post it using the ip_input function to the upper layer. Question: what would be wrong in my code that the upper TCP layer is not returning the received buffer.that means lwip_read function not returning recevied buffer value. pls suggest. NOTE:I am succesfully able to post data using this GITHUB code mentioned above. -- View this message in context: http://lwip.100.n7.nabble.com/lwip-ppp-lower-physical-layer-to-app-layer-communication-tp24280.html Sent from the lwip-users mailing list archive at Nabble.com. _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
