Hy
Currently I'm working on reading data from a device before they get to the transmitter.
Currently I like to use the SoftSerail port 2 and 3 to receive and send the data out.
while(c3.available() > 0){
byte tempit = c3.read();
c3.write(tempit);
}
However when I use the Hardware Serial Port it does work:
while(Serial.available() > 0){
byte tempit = Serial.read();
Serialwrite(tempit);
}
even when I read the data from the SoftSerial Port and send it through the Hardware port this works as well;
while(c3.available() > 0){
byte tempit = c3.read();
Serial.write(tempit);
}
Can someone help me to get this working an the tx SoftSerialPort

SoftwareSerial cannot transmit and receive at the same time - you must choose one or the other.
I wonder if a slight delay between reading and writing would help - though it might not suit the logic of what you want to do.

Serialwrite(tempit);
Did anybody notice the missing FULL STOP in the "Serial.write(tempit); statement ?

Or change your micro to another capable of 2 hardware serial ports, some AVR examples (from cheaper to more expensive):
ATmega164A

thx for all the comments.
Hmm so I have to look for another micro... Hope there are PCB as small as the Arduino Pro Mini 328...

Lighten up - it was meant as a joke.
