Hola alguien q me ayude con q pines se une un arduino mega y el sim900, para q funcione el codigo, en el monitor serie se queda en "++AT"
Hi I change the Serial to mySerial n use the 2,3 as Rx Tx in Arduino Uno with SIM800, but still didn't get any response after sending connect request, am not getting any response Here is my serial terminal output. can u please help me to solve this issue..?

12:15:30.515 -> CONNECT 12:15:30.515 -> MQTT.TCP_Flag = True
any help???
Same issue !! not working.. got stuck at MQTT.MessageFlag = true; any solution ?
i change the sim its working now
For all those getting stuck at MQTT.MessageFlag = true
when using software serial, ESP8266 or other platforms, change GSM_MQTT::processing
in GSM_MQTT.cpp
to
void GSM_MQTT::processing(void)
{
if (TCP_Flag == false)
{
MQTT_Flag = false;
_tcpInit();
}
_ping();
//**************new code*****************
unsigned long t = millis();
//add long waitPeriod = 0; somewhere at the beginning of the file
if (t - waitPeriod > 1000L)
{
waitPeriod = t;
serialEvent(); //call serialEvent every second
}
//*****************************************
}
code works perfectly fine!!!!!!!!!!!!!!!!!!
Hi, First of all, a wonderful job for creating such library. Issue: When i look into the source, "Serial" (Hardware Serial) has been used to communicate with the SIM800 modem and mySerial has been used to print the output.
I am using MEGA, where i need to use "Serial1" to communicate with SIM800 and "Serial" to print the output. So i replaced the occurrence of "Serial" with "Serial1" and "mySerial" with "Serial". I didn't change any other code. The library is not working anymore.. Can you please help to make it little flexible with respect to choosing the serial ports.
