I'm trying to upload to arduino wirelessly without using usb cable, after looking through numerous tutorial online/youtube i still could not figure it out. I have changed the HC-05 to slave and set it at 57600 baud rate, and im following this tutorial but i could not achieve what was shown in the video:

I have attached a screenshot of the issue on arduino, and a drawing of my connection.
Any help will be much appreciated!!
Thank you

Have you tried the other alternative processors?

The Nano has three processor options under the Tools menu.

Oh yes, sorry i misunderstood your question.

There are:
ATmega328P
ATmega328P (Old Bootloader)
Atmega168

All does not work, gives the same error.

In the video the selected port is HC-05 but you've got COM11 selected.

How can it communicate when send and receive are on different ports?

Rather than the video, take a look at the article, including the uddates https://sites.google.com/site/wayneholder/inexpensively-program-your-arduino-via-bluetooth

Did you do the first part...where he attaches the HC-05 and puts it into programming mode, changes the baud rate (for programming) and the password - all using a term and an FTDI board?

You may also want to first make sure that you can pair with and communicate with the HC-05 without the Arduino at all. There are terminal programs just for this purpose, like this one https://www.microsoft.com/en-us/p/bluetooth-serial-terminal/9wzdncrdfst8?activetab=pivot:overviewtab

On an Android tablet, I have used this one many times https://play.google.com/store/apps/details?id=project.bluetoothterminal&hl=en_US

I'm not sure that you have this first part done right.
