Hi guys,
I'm having problems transmitting data from my Uno to my Mega2560 but i can send data from my Mega to my Uno instead.
Why is that so? I'm using the Software Serial Example program to do the communication part.
Anyone here can help me?
Thanks.

I'm having problems

What problems?

I'm using the Software Serial Example program to do the communication part.

On which Arduino? Using what pins? Why are you doing software serial on a device with 4 hardware serial ports, if you are using SoftwareSerial on the Mega?

Anyone here can help me?

Not without a lot more details.

Did you connect ground between the two? Seems to be a common problem.
