在图片中,当我放置线条时,相同的代码似乎不起作用
if (gsm.begin(9600)) //Start the GSM COM
{
(sms.SendSMS("+8613668914901","Your Home Security system is being bridged"));
但是这条线在 void setup 函数中工作得很好。
我该如何解决这个问题?在 void 设置中,草图工作正常,但是当我也将代码放入函数 CheckPassword 时,它不会发送 SMS。
我还尝试创建一个函数,比如说 void SMS 并在 checkPassword 函数中调用它,但它不能解决问题,顺便说一句,在 void 设置中调用相同的函数可以正常工作。
