Arduino Nano and HC-05 Bluetooth module upload issue

[qkaifong]

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?

Mike.

 

[qkaifong]

No i did not, i only have arduino nano and uno with me

 

[Pommie]

The Nano has three processor options under the Tools menu.

Mike.

 

[qkaifong]

Oh yes, sorry i misunderstood your question.

There are:
ATmega328P
ATmega328P (Old Bootloader)
Atmega168

All does not work, gives the same error.

 

[Pommie]

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

Mike.

 

[qkaifong]

Yup, COM11 to my bluetooth module .

Thank you so much for your quick response!!

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

Mike.

 

[qkaifong]

Hmmm.. i'm not too sure.
I'm using windows, i do not have the same selection port as the one in the video.

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.
