I'm trying to get the softwareSerial example to work on my arduino uno. As seen in the code below it should return "Hello, world?" from the mySerial towards the serial port/monitor. Why am i not receiving anything from mySerial?

If you are like most other people, it's because you don't have anything connected to the pins that the SoftwareSerial instance is talking to.
Where is your code? What is connected to the SoftwareSerial instance's pins?
I'm trying to get a response from my HC-05 Bluetooth module. Connections are as following:
The hardware is ok, the LED from the HC-05 should blink in 2 second when it is in AT mode(mode to program the module).
In the datasheet is stated when i send AT with my serial monitor i should get a response OK. I'm getting nothing.
How can i check if mySerial is created and working? So echoing towards the serial monitor.
