SM5100B GSM デバイスを制御するために Arduino を使用しています。別の SMS を受信した後に SMS を送信する場合を除いて、すべてが機能します。私はこれを得る、

前述の受信 SMS を処理するための私のコード:
#include <SoftwareSerial.h> //Include the NewSoftSerial library to send serial commands to the cellular module.
char inchar; //Will hold the incoming character from the Serial Port.
SoftwareSerial cell(2,3);
char mobilenumber[] = "0597010129";
void setup() {
//GSM
Serial.begin(9600); // opens serial port, sets data rate to 9600 bps
Serial.println("Initialize GSM module serial port for communication.");
cell.begin(9600);
delay(35000); // give time for GSM module to register on network etc.
Serial.println("delay off");
cell.println("AT+CMGF=1"); // set SMS mode to text
delay(200);
cell.println("AT+CNMI=3,3,0,0"); // set module to send SMS data to serial out upon receipt
delay(200);
}
void loop() {
if(cell.available() >0)//If a character comes in, from the cellular module
{
inchar=cell.read();
Serial.println(inchar);
if (inchar=='#'){ // OK - the start of our command
delay(10);
inchar=cell.read();
Serial.println(inchar);
if (inchar=='a'){
delay(10);
Serial.println("The folowing SMS : \n");
inchar=cell.read();
Serial.println(inchar);
if (inchar=='0'){ //sequance = #a0
Serial.println("#a0 was received");
}
else if (inchar=='1'){//sequance = #a1
Serial.println("#a1 was received ");
sendSms();
}
}
cell.println("AT+CMGD=1,4");// AT command to delete all msgs
Serial.println(" delete all SMS");
}
}//end of if(cell.available() >0) {...}
}
void sendSms(){
//cell.println("AT+CMGF=1"); // set SMS mode to text
cell.print("AT+CMGS="); // now send message...
cell.print((char)34); // ASCII equivalent of "
cell.print(mobilenumber);
cell.println((char)34); // ASCII equivalent of "
delay(500); // give the module some thinking time
cell.print(":D hello m3alleg :D"); // our message to send
cell.println((char)26); // ASCII equivalent of Ctrl-Z
