Hi :)This not for reporting an issue, it's a question. I'm trying to make your code work but there is an error right after the Serial.println("AT+CMQTTSTART"); . The response of the error is:

+CMQTTSTART: 23

ERROR,
which from the datasheet of my SIM7600E-H module means "network is opened". I can't really understanding what that means. I was wondering if it had happened to you and if you could help.

Thank you!

It is not an issue but a question.

Thanks

Hello, I am from India. I want to confirm does it works with Jio sim too or not? For that to work it will have to support Volte. Please tell us if you have tested it on Jio sim yet. If in case it is not working, then is there some sort of firware upgrade available to make it fully functioning or not?

If I add another softwareserial device it's cause no response from sim module.

Softwareserial testdevice(8,9);

While testdevice continue to work but same time sim module not able to send at command response. If I remove testdevice then sim module continue to work.

Hi! I think this is not a issue, better a question or a doubt.

Exist any method to make more fast? I explain me :

For example for send a message , take at least 5000 ms ( 5 seconds)
I attempt to reduce the delay time, but in some cases get a ERROR.
For another when receive a msg, at least 2~3 seconds to get.

Actually i was using a old SIM800L (2G) with the Pubsubclient library and the time is very low than with the sim7600E.
Is there any option to reduce the time?

Sorry in advanced, excuse me for my english, is a little bad.

  Serial.println("Publishing Message: LED ON");
  mySerial.println("AT+CMQTTTOPIC=0,8"); //AT Command for Setting up the Publish Topic Name
  **delay(1000);**
  mySerial.println(Publish); //Topic Name
  **delay(1000);**
  mySerial.println("AT+CMQTTPAYLOAD=0,1"); //Payload length
  **delay(1000)**;
  mySerial.println("a"); //Payload message
  **delay(1000);**
  mySerial.println("AT+CMQTTPUB=0,1,60"); //Acknowledgment
  **delay(1000);**
