Among things I tried to following:- Change the baud rate for both software and hardware serial (9600 for instance).- Tried a different SoftwareSerial library (AltSoftSerial).- Tried different RX and TX pins for SoftwareSerial.- Instead of Serial.write(mySerial.read()), store the result in a char first.

The example code is below, the example can be found hereĪs far as I understand this, the following should happen:- Type text in Serial Monitor window.- Serial.read() reads this data and writes it to the Software Serial.- The Software Serial reads this data and writes it back to Serial.- That which was written appears on the screen.īut whatever I try, nothing happens. Problem is, I can't get the most basic example to work and I have been stuck on this for quite a while now. To become familiar with (software) serial communication on the Arduino, I reviewed the documentation of the SoftwareSerial library. I figured I would need to use the SoftwareSerial library to read the incoming data and print that data on my screen using the hardware serial and the Serial Monitor in the Arduino IDE. The meter uses serial communication and I would like to see the values being outputted on my laptop screen.

I recently bought an Arduino UNO to read the data outputted by my Smart Meter. I conducted research on the internet and saw that the processor that hardware (ATmega328) has only one UART, and by default this Arduino has dedicated 1 pin TX and one RX, but also saw that it would be possible in the Arduino UNO, which has the same processor, work with 2 serial communications using the SoftwareSerial library, it would be possible that the Arduino Nano?gre_gor

I wonder if it is possible to program the Arduino Nano for this task. I'm working on a project that needs to use at least 2 serial communications (2 TXs and RXs) alternately and in different pins. This hardware allows the Atmega chip to receive serial communication even while working on other tasks. The native serial support happens via a piece of hardware (built into the chip) called a UART. The Arduino hardware has built-in support for serial communication on pins 0 and 1. Each Arduino board has at least one serial port. What is Serial Communication? Serial communication is used to exchange data between the Arduino board and another serial device such as computers, displays, sensors and more. Serial (TTL) - Digital pins 0 and 1 are the serial pins of the Arduino Uno.
