Я застрял на час с ошибкой, и это меня бесит. У меня есть следующий код (конечно, внутри основной функции):
if (GSM_Available()){
//1st, we'll see if some SMS are stored in the memory.
if(send_AT_command_UART("AT+CMGR=1,0","OK\r") == 1){
//If we receive an ok, it means that there is no sms received recently.
continue;
}else{
//If we arrive here, we know that there is at least one recently received sms.
//We have to read the UART string received (the answer from the AT command) in order to retrieve the SMS from it.
char *answer;
int y=0;
char *newSensorAdress;
//char bidule[2][64]; //Array which will contain the alert threshold temperature, the humid
UARTReadString(answer,128);
//Ok now we have the answer. We have to take the "data" field from the answer.
for(int i=0;i<strlen(answer);i++){
//Ok, so from m66 datasheet we know that the text of the received sms is located right after a carriage return plus a line feed characters.
if(answer[i-1] == '\r' || answer[i] == '\f'){
//We now know that the sms starts at this index, after these 2 characters.
y=i;
}
}
//Now, we iterate over the sms field to find what kind of sms it is (if it is an expected sms, or a bullshit sms)
//1st character of the sms (e.g y+1) will determine the kind of frame we receive.
switch(answer[y+1]){
case 1:
//Here, it is the frame wich says the adress of the sensor to add to the network. We'll write this sensor into the EEPROM
//The frame is in this format : 1;abcdabcd. With the sensor's adresse starting at the first 'a'
//So, we'll iterate, and the index starts at y+3 (y+2 is ';')
int indexNewSensor=0;
for(int i = y+3;i<strlen(answer);i++){
//The adress is for now received as a string
strcpy(newSensorAdress[indexNewSensor],answer[i]);//Filling the newSensorAdress string. Sensor
indexNewSensor++;
}
//Then, once filled, this adress must be written into the EEPROM for the central station to remember it
break;
case 2:
//Here, it is the frame which says the adress of the sensor to delete of the network. We have to delete the adresse of the network from the EEPROM
//For now, I don't know
break;
case 3:
//Here, it is the frame which sends the boundary temperature, boundary humidity temperature, measurement frequency
char *sub_string="";
int newIndex=0;
//1st, we'll fill a new string containing ;ab;ab;abcd
for(int i = y+2;i<strlen(answer);i++){
strcpy(sub_string[newIndex],answer[i]);
newIndex++;
}
//Now, we'll look for the delimitters, and put in a array of string each substring
char *pch = strtok(sub_string,";");
break;
default:
//Here, we have to deal when the 1st character is not a number, which means it does not match any known frame
//We juste have to ignore the sms
break;
}
}
}
И вот ошибка, которую я получаю:

GSM_available (), send_command_AT_UART () являются функцией OF COURSE, уже определенный в другом файле (который бессмысленно показывать, поскольку тесты, выполненные в прошлом, показывают, что эти две функции работают ОТЛИЧНО).
