Topic: Original Arduino GSM Library - change RX / TX to Hardware Serial (Read 2891 times) previous topic - next topic

Hej guys,

is anybody of you familiar with the original Arduino library gsm.h and can help me?

I need to change the rx tx pins from software serial to hardware serial (channel 2 on the Arduino Mega).

Is it possible?
I already tried the Rxpin / Txpin from GSM3Softserial.cpp to 16/17 (pins of Serial2 on the Mega) but it did not work.

Regards!

GSM3SoftSerial was designed for emulate a serial port by software, not for hardware native serial port. You have to modify it or create a new code for it.
If you can use a serial port emulate by software, RX pin must be a pin with support for interruptions.


is it possible for me to use Original Arduino GSM Library with other GSM shield (not original GSM shield as well) for example from DFRobot? if it could, in which part i must adjust?

davidgoth

You can modify it. The most important things are software serial communication, commands compatibility, software flow control and responses times.

Could you solve the problem? I have got the same problem. I want to use hardwareserial.

davidgoth

In theory, you can replace all references to SoftwareSerial with Serial class.
