部件号：MSP432P401R 我正在通过串行通信将sim868模块接口与msp432p401r控制器配合使用。 我想在服务器上发布数据。但代码没有发布数据。当我从msp432向sim868发送"AT+HTTPREAD"命令时，我得到了响应{}(空白括号)。 我正在向sim868发送“AT+HTTPDATA=19210000”命令，我得到了“下载”响应，1万毫秒后我也得到了正常响应。数据将在1万毫秒内开机自检。
下面是我的代码：-
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
//以中断方式接收数据
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??
