范例
// 函式库 #include <GSM.h> // PIN 码 #define PINNUMBER "" // 初始化 GSM 函式库 GSM gsmAccess; GSMVoiceCall vcs; // 用来存放电话号码的字元阵列 char numtel[20]; void setup() { // 初始化 Serial Serial.begin(9600); Serial.println("Receive Voice Call"); // 连线状态 boolean notConnected = true; // 启动 Arduino GSM shield,如果你的 SIM 卡有 PIN 码,请当作 begin() 的参数 while(notConnected) { if(gsmAccess.begin(PINNUMBER)==GSM_READY) notConnected = false; else { Serial.println("Not connected"); delay(1000); } } // 先挂断通话,避免待会误判 vcs.hangCall(); Serial.println("Waiting Call"); } void loop() { // 检查通话的状态 switch (vcs.getvoiceCallStatus()) { // 什麽事都没发生 case IDLE_CALL: break; // 当没有播打电话的时候,不会发生这个情况 case CALLING: Serial.println("CALLING"); break; // 有来电! case RECEIVINGCALL: Serial.println("RECEIVING CALL"); // 取得来电号码 vcs.retrieveCallingNumber(numtel, 20); // 输出来电号码到序列埠监控视窗 Serial.print("Number:"); Serial.println(numtel); // 接听来电 vcs.answerCall(); break; // 通话中 case TALKING: Serial.println("TALKING. Enter line to interrupt."); while(Serial.read()!='\n') delay(100); vcs.hangCall(); Serial.println("HANG. Waiting Call."); break; } delay(1000); }
