I am using sim868 module interface with msp432p401r controller through serial communication. I want to post the data on server.But code is not posting the data.When i send"AT+HTTPREAD"command to sim868 from msp432 i got response{}( blank bracket). I am sending " AT+HTTPDATA=192, 10000" command to sim868 i got response " DOWNLOAD" and after 10000 ms i got ok response also.the data will post within 10000 ms.
Below is my code:-
uart_puts((char *)"AT"); // COMMAND FOR INITIALIZING GSM uart_putc(0x0D);//CARRIAGE RETURN __delay_cycles(1000000);//DELAY...WAIT FOR OK FROM GSM ok_response(); uart_puts((char *)"AT+SAPBR=3,1,\"Contype\",\"GPRS\""); // COMMAND FOR INITIALIZING GSM uart_putc(0x0D);//CARRIAGE RETURN __delay_cycles(1000000);//DELAY...WAIT FOR OK FROM GSM ok_response(); uart_puts((char *)"AT+SAPBR=3,1,\"APN\",\"internet\"");//SEND A MESSAGE TO PARTICULAR NUMBER uart_putc(0x0D); __delay_cycles(1000000);//DELAY...WAIT FOR OK FROM GSM ok_response(); uart_puts((char *)"AT+CGATT=1"); // AT commands to initialize gsm modem uart_putc(0x0D); __delay_cycles(1000000);//DELAY...WAIT FOR OK FROM GSM ok_response(); uart_puts((char *)"AT+SAPBR=1,1"); // AT commands to initialize gsm modem uart_putc(0x0D); __delay_cycles(100000000);//DELAY...WAIT FOR OK FROM GSM ok_response(); uart_puts((char *)"AT+SAPBR=2,1"); // AT commands to initialize gsm modem uart_putc(0x0D); __delay_cycles(1000000);//DELAY...WAIT FOR OK FROM GSM ok_response(); uart_puts((char *)"AT+HTTPINIT"); // AT commands to initialize gsm modem uart_putc(0x0D); __delay_cycles(1000000);//DELAY...WAIT FOR OK FROM GSM ok_response(); uart_puts((char *)"AT+HTTPPARA=\"CID\",1"); // AT commands to initialize gsm modem uart_putc(0x0D); __delay_cycles(1000000);//DELAY...WAIT FOR OK FROM GSM ok_response(); uart_puts((char *)"AT+HTTPPARA=\"URL\",resonics.xyz:8995/.../data"); // AT commands to initialize gsm modem uart_putc(0x0D); __delay_cycles(1000000);//DELAY...WAIT FOR OK FROM GSM ok_response(); uart_puts((char *)"AT+HTTPPARA=\"CONTENT\",\"application/x-www-form-urlencoded\""); // AT commands to initialize gsm modem uart_putc(0x0D); __delay_cycles(1000000);//DELAY...WAIT FOR OK FROM GSM ok_response(); uart_puts((char *)"AT+HTTPDATA=99,100000"); // AT commands to initialize gsm modem uart_putc(0x0D); __delay_cycles(5000000); b=a; if( buff[b-3]=='D') { count=count+1; __delay_cycles(5000000); uart_puts((char *)"{ \"testID\" : 1, \"testLevel\" : 1, }"); // AT commands to initialize gsm modem uart_putc(0x0D); __delay_cycles(5000000); //DELAY...WAIT FOR OK FROM GSM } else { variable=variable+1; } uart_puts((char *)"AT+HTTPACTION=1"); uart_putc(0x0D); __delay_cycles(5000000);//DELAY...WAIT FOR OK FROM GSM ok_response(); uart_puts((char *)"AT+HTTPREAD"); uart_putc(0x0D); __delay_cycles(5000000);//DELAY...WAIT FOR OK FROM GSM
// receive data in interrupt
if (EUSCI_A0->IFG & EUSCI_A_IFG_RXIFG)
{
EUSCI_A0->IFG &=~ EUSCI_A_IFG_RXIFG;// Clear interrupt
// Echo the received character back
buff[a]= EUSCI_A0->RXBUF;
a++;
}
Please tell me where i am going wrong in code??
