Arm 从LPC2148向移动电话发送SMS
我昨天发布了一个类似的问题，但我无法编辑代码并发布更多问题，所以我将其重新发布在这里。我已将gsm调制解调器连接到LPC2148，正在向手机发送一条简单的信息“vehicle”。我把打印语句放在中间，这样我就知道程序在哪里了。它运行所有打印语句，但消息未发送 这是代码 Main.cArm 从LPC2148向移动电话发送SMS,arm,gsm,at-command,uart,lpc,Arm,Gsm,At Command,Uart,Lpc,我昨天发布了一个类似的问题，但我无法编辑代码并发布更多问题，所以我将其重新发布在这里。我已将gsm调制解调器连接到LPC2148，正在向手机发送一条简单的信息“vehicle”。我把打印语句放在中间，这样我就知道程序在哪里了。它运行所有打印语句，但消息未发送 这是代码 Main.c #include "i2c.h" #include "LPC214x.H" // LP

对于（i=0；i，这里有两种方法从根本上说是处理AT命令的错误方法
首先，决不，决不，决不，决不，决不，决不使用函数delaygsm这样的延迟。您必须更改处理逻辑，以便在发送命令后，除了从调制解调器读取响应外，您什么也不做，直到在开始下一个命令之前获得最终结果代码。有关详细信息，请参阅
使用ATE0关闭echo只会使您需要解析的文本稍微减少，但没有办法。您必须阅读并解析调制解调器返回的响应。这并不复杂，只需按照上面链接的答案中给出的说明进行操作即可
另外请注意，AT命令行应仅以'\r'
（或写为0x0d
）终止，而不应以其他方式终止，有关详细信息，请参阅
