Bluetooth connection and RX ,TX
As commenter by RSM

The issue you are facing is because you are using pins 0 and 1

These are used by the arduino for uart. 

So for starters please use any pin other that 0 and 1.  But if you insist that you do need to use these pins,  then you don't need softwareserial you can use the default serial itself, but you will need to disconnect the bluetooth while programming.
