我写了这段代码(使用Codeblocks),我希望将GSM的消息发送到我的手机。它包括一些AT命令。问题是我在printf中有这个错误,at + cmgf = 1。我认为我的代码是正确的。 UTF或ASCII有什么问题吗?

#include <stdio.h> // standard input / output functions
#include <string.h> // string function definitions
#include <unistd.h> // UNIX standard function definitions
#include <fcntl.h> // File control definitions
#include <errno.h> // Error number definitions
#include <termios.h> // POSIX terminal control definitions


int open_port(void)
 {
int fd; // file description for the serial port

fd = open("/dev/ttyAMA0", O_RDWR | O_NOCTTY | O_NDELAY);

if(fd == -1) // if open is unsucessful
{
    printf("open_port: Unable to open /dev/ttyAMA0. \n");
}
else
{
    fcntl(fd, F_SETFL, 0);
    printf("port is open.\n");
}

return(fd);
 } //open_port

int configure_port(int fd)      // configure the port
{
struct termios port_settings;      // structure to store the port settings in

cfsetispeed(&port_settings, B9600);    // set baud rates
cfsetospeed(&port_settings, B9600);

port_settings.c_cflag &= ~PARENB;    // set no parity, stop bits, data bits
port_settings.c_cflag &= ~CSTOPB;
port_settings.c_cflag &= ~CSIZE;
port_settings.c_cflag |= CS8;

tcsetattr(fd, TCSANOW, &port_settings);    // apply the settings to the port
return(fd);

 }
 void init_gsm()
 {
  printf("at+cmgf=1\r\n");
  printf("at+cmgs=\"60*****\"\r\n");
  printf("Hello\r\n%c",26);  
 }
int main(void)
{
int fd = open_port();
configure_port(fd);
//query_modem(fd);
init_gsm();
return(0);

} //main

1 个答案:

答案 0 :(得分:1)

stray '\302'的问题是代码在某处包含非中断空间而不是普通空格。

然而,解决这个问题,我发现了另外两个问题here
