Arduino UNO, SoftwareSerial and CC128

Using Arduino Networking, Protocols, and Devices

Hi, I’m trying to communicate with a CurrentCost EnviR to get the message it sends every 6 seconds through the serial at 57600 baud but I only receive strange characters.

Trying to figure what was going on I connected pin 0 (Hardware Serial Rx) to pin 2 and set that pin as Software serial Rx. Then I send to the Hardware Serial whatever I receive through SoftwareSerial (which is exactly the same that I send through the Hardware Serial). This way I can monitor what is going on.

It works great for 4800, 9600, 14400 and 19200 baud but after that I only get garbage.

My guess is that the timings for the 57600 are wrong in the library.

The CurrentCost serial communication specs are here: Current Cost CC128 Display Unit

My sketch is this one:

#include <SoftwareSerial.h>

#define rxPin 2
#define txPin 300
#define ledPin 5

SoftwareSerial currentcost(rxPin, txPin);

void setup()  
{
  Serial.begin(57600);
  Serial.println("Arduino here!");

  // set the data rate for the SoftwareSerial port
  pinMode(rxPin, INPUT);
  currentcost.begin(57600);

  pinMode(ledPin, OUTPUT);

}

void loop() {
  if (currentcost.available()) {
    Serial.print((char)currentcost.read());
    //digitalWrite(ledPin, HIGH);
  }
  else {
    //digitalWrite(ledPin, LOW);
    //Serial.println();
  }  
}

Does anyone know how can I get this to work?

Thanks a lot!
