【问题描述】:
我在 mac 电脑上设置了 arduino IDE,并将 Arduino uno 与 GSM 模块 SIM800L EVB 一起使用
我使用以下代码块通过此模块发送短信。
#include <GSM.h>
#define PINNUMBER ""
// initialize the library instance
GSM gsmAccess; // include a 'true' parameter for debug enabled
GSM_SMS sms;
// char array of the telephone number to send SMS
// change the number 1-212-555-1212 to a number
// you have access to
char remoteNumber[20]= "12125551212";
// char array of the message
char txtMsg[200]="Test";
void setup()
{
// initialize serial communications
Serial.begin(9600);
Serial.println("SMS Messages Sender");
// connection state
boolean notConnected = true;
// Start GSM shield
// If your SIM has PIN, pass it as a parameter of begin() in quotes
while(notConnected)
{
if(gsmAccess.begin(PINNUMBER)==GSM_READY)
notConnected = false;
else
{
Serial.println("Not connected");
delay(1000);
}
}
Serial.println("GSM initialized");
sendSMS();
}
void loop()
{
// nothing to see here
}
void sendSMS(){
Serial.print("Message to mobile number: ");
Serial.println(remoteNumber);
// sms text
Serial.println("SENDING");
Serial.println();
Serial.println("Message:");
Serial.println(txtMsg);
// send the message
sms.beginSMS(remoteNumber);
sms.print(txtMsg);
sms.endSMS();
Serial.println("\nCOMPLETE!\n");
}
当我尝试时,控制台上出现以下错误。考虑这是我第一次使用这项技术。并且不确定我是否必须设置任何驱动程序才能使用 GSM 模块。
avrdude: stk500_loadaddr(): (a) protocol error, expect=0x14, resp=0x00
avrdude: stk500_paged_load(): (a) protocol error, expect=0x14, resp=0x00
avrdude: stk500_cmd(): programmer is out of sync
avr_read(): error reading address 0x0000
read operation not supported for memory "flash"
avrdude: failed to read all of flash memory, rc=-2
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x00
什么是错误?以及修复它的步骤是什么?

从那里删除

应该在这里删除,因为它专门针对 Arduino 硬件并且更适合那里。
