智能超重报警系统的设计与实现
rebuff = sim900a_waitask(0); //重新等待消息

}
else if(strstr(rebuff,\ //响应NO ANSWEER无人接听 {

} } } } ...... }
另外GSM需使用串口通信，故串口设置如下： /**

void USART1_Config(void) {
GPIO_InitTypeDef GPIO_InitStructure; USART_InitTypeDef USART_InitStructure;
/* config USART1 clock */

4.3 蓝牙部分
由于蓝牙模块主要听过串口收发数据，所以设置好相应串口即可 /*
