HC05 Bluetooth module works with Arduino Uno but not Nano

I can get my serial AT commands to work with the Uno but when I try and sent AT commands with my Nano it won't work. I think I might actually have actually bought a knock off nano so it's possible that the RX and TX are just not working right but the rest of the board works fine so I don't think that's it.

Any suggestions? The wiring should be good (rx --> rx, tx --> voltage divider --> tx, 5V --> VCC, GND --> GND, 5V --> Wake).

To be clear, I use this wiring on the Uno then immediately switch it to the nano and it doesn't work.

Have a look at my gps issue that sounds like a similar issue. Works fine on UNO but failed on the NANO
