The wrong 1 byte values are being sent or received(I don't know) when using SoftwareSerial between Arduino leonardo and Arduino UNO. UNO and Leo are connected via:

  • gnd
  • pin 9 and 8

here is the code that runs on leonardo:

//LEO
#include <SoftwareSerial.h>

const byte rxPin = 9;
const byte txPin = 8;

SoftwareSerial sserial (rxPin, txPin);

void setup() 
{
  Serial.begin(115200);
  sserial.begin(115200);
}

void loop() 
{
  if(sserial.available())
  {
    uint8_t recv = 0;
    sserial.readBytes(&recv, 1);
    Serial.println(recv);
    for(int i = 0; i < 8; i++)
    {
      if(bitRead(recv, i))
      {
        Serial.print("1 ");
      }
      else
      {
        Serial.print("0 ");
      }
    }
    Serial.println();
  }
}

and here is the code that runs on UNO:

//UNO
#include <SoftwareSerial.h>

const byte rxPin = 8;
const byte txPin = 9;

uint8_t count = 0;
unsigned long last_send = millis();

SoftwareSerial sserial (rxPin, txPin);

void setup() 
{
  Serial.begin(115200);
  sserial.begin(115200);
}

void loop() 
{
  if(millis() - last_send > 500)
  {
    count++;
    last_send = millis();
  }
  sserial.write(&count, 1);
  delay(100);
}

and here is the output I'm getting in the Serial Monitor of Arduino Leonardo:

You can see that the values received are not in order they should be in. Format: value \n its bit representation. Any ideas what I might be doing wrong or why this is not working properly.

I have tried all the combinations of pins 8 - 13. I was expecting the values to be in order as they should be, each next incremented by one(on half a second basis).

    use lower baud rate. on Leonardo you can use hardware Serial1 – Juraj Mar 05 '23 at 18:01
  • You mean rx and tx pins at the bottom? Otherwise if u mean scl and sda pins... I know, however I am using USB host shield attacked to my leonardo therefore that is not an option – GPlays Mar 05 '23 at 19:11
  • USB Host Shield uses SPI. Serial1 on Leonardo are pins 0 and 1 labeled RX1 and TX1 – Juraj Mar 05 '23 at 20:27

The issue seemed to be the baud rate I was able to get reliable data transmission with baudrates up to including 74880
