SIM7000E Arduino - Once in two I have this error "faile to set baud rate"

Hello,

I test the SIM7000E Arduino NB-IoT/LTE/GPRS/GPS Expansion Shield on my Arduino Mega ( with D8 connected with D10 ) and I have an issue with sim7000.setBaudRate(19200);

Once in two I have this error "faile to set baud rate".

Can you help me?

Thx for your replay.
It's work !

2021-02-24 18:01:12 You need to initialize the soft serial port and add a line of code
mySerial.begin(9600), the parameter is the baud rate 347945801

2021-02-10 02:30:09 Hello,

Please found an exemple:

Code: Select all

 #include <Wire.h>
#include <DFRobot_SIM7000.h>
 
SoftwareSerial     mySerial(10, 7); // with link between D8 - D10 on my Mega.
DFRobot_SIM7000    sim7000;
 
 
void setup() 
{   
    Serial.begin(115200);     
    sim7000.begin(mySerial);
    
    sim7000.turnOFF();
    Serial.print("Turn OFF SIM7000 ");
    for(int i=0 ; i < 6; i++)
    {
      delay(1000);
      Serial.print(".");
    }
    Serial.println(" OK");
 
    Serial.print("Turn ON SIM7000 ...");
    if( sim7000.turnON() )
      Serial.println(" OK");
    else
      Serial.println(" Failed !");
      
    delay(2000);
    
    Serial.print("Set baud rate: 19200 ...");
    if( sim7000.setBaudRate(19200) )
      Serial.println(" OK");
    else
      Serial.println(" Failed !");
        
    delay(2000);     
}
 
void loop()
{
  Serial.print(".");
  delay(1000);
}
