I assume what you see in the first picture is what you expect to see - even the one where I guess you hit enter with no text. This proves nothing is wrong with the code or hardware but says nothing about bluetooth.
The second shows the bluetooth is at least paired and transmits. I'm at a bit of a loss to explain why you have transmit and no receive. I'm not familiar with your terminal programme but I doubt the problem lies there. The wiring is obviously not the wrong way round but it could still be suss on Rx.
