mqtt-and-sim800-900's Issues

How to modify the Arduino uno version？

Can't comunicate with the module SIM800

The arduino can't talk with the SIM800 module.

I'm usign the mqtt_basic_pub_and_sub example and I include HardwareSerial.h under an Arduino Mega.

I put an Serial.println in attempt to watch the answer of the module when the library sim800 sends an clean "AT", and the answer in spite of be "OK" is "⸮"
I change several times the ports on the arduino with the same behaviour.

What can I'm doing wrong?
I'll really apresiate your help.
