Anyone connected a Arduino(Mega) to a HC-05 Bluetooth in Windows 10 ?

Been trying for days to get my Arduino Mega to talk to the attached HC-05 Bluetooth module but it HC-05 simply wont respond to any AT commands.

Its 100% in AT mode with a slow flashing Red light (by holding button on HC-05 when powering it on), I'm happy its wired to the Arduino correctly .

Tried all Baud rates, especially 38400 & 9600, even pressed button when sending the commands.

When I enter AT (or anything else) & SEND NOTHING happens. I've also got LF & CR at bottom of Serial Monitor in Sketch & correct Port & Board are selected.

I'm sure its something to do with Windows 10, just not sure what.

Anyone got this to work ?

Notwithstanding how troublesome Windoze 10 has proven to be, if you can talk to a program on the Mega with Win 10 and have it talk back to you on the Serial Monitor, any problem with the addition of a Bluetooth module will be a problem in the code.

You need to describe - with diagrams - what you are actually connecting to what here, what simpler program you already tried that worked, and then cite your current code according to the instructions.

Swap the TX and RX wires and try again

And .....Have you looked at the guides on line , connected pin 4 correctly ?
