Hello , I want to use LWIP stack (2.0.2) with pppos.I have NXP MC5748 board wi SIM800c interface with one UART channel.I have use following AT commands to configure GSM module:
#define msg1 "AT\r\n"#define msg2 "ATE0\r\n"#define msg3 "AT+CFUN=1\r"#define msg4 "AT+CNMI=0,0,0,0,0\r"#define msg5 "AT+CPIN?\r"#define msg6 "AT+CREG=1\r"#define msg7 "AT+CGDCONT=1,\"IP\",\"airtelgprs.com\"\r"#define msg8 "AT+CGDATA=\"PPP\",1\r"#define msg9 "ATD*99***1#\r" I am successfully getting following data from GSM module. status_cb: Connected our_ipaddr = 100.95.137.40 his_ipaddr = 192.168.254.254 netmask = 255.255.255.255 dns1 = 59.144.144.46 dns2 = 59.144.127.117 Next step, I am trying to ping 8.8.8.8 But I am getting Timeout error lwip_socket(PF_INET, SOCK_RAW, 1) = 1lwip_sendto(1, data=0x40040728, short_size=40, flags=0x0 to=8.8.8.8 port=42405ping: send 8.8.8.81. lwip_recvfrom(1, 0x40008cb8, 64, 0x0, ..)2. lwip_recvfrom: top while sock->lastdata=0x04. lwip_recvfrom: netconn_recv err=-3, netbuf=0x05.lwip_recvfrom(1): buf == NULL, error is "Timeout."! Is there any step i am missing to configure ? For more information I have attached log file ThanksRahul
