Added script to wirelessly transfer compiled firmware script

[saadatq]

I have added the script for wireless transfer as well as a readme file with instructions.

Please test out the script and let me know if there are any changes to be made.

[BlakeFreer]

only want to transfer a single binary file, not the whole folder

Changes have been made as requested. Let me know if you need anything else from me.

@CameronBeneteau can you test this on the Pi? You should be able to transfer a file from your laptop to the Pi with it

[CameronBeneteau]

The file transfer works, but it's not as robust as we would like. Here are a few suggestions that will make it better:

I tested it with the pi and the current behaviour is as follows:

• The command fails when the destination path is a path (since it doesn't exist on the pi)
• The command fails when the destination path is left blank
• If the destination path is a file, the transferred file on the pi is named to this

I would recommend changing it for the following behaviour:

• A blank destination path will transfer the file (with the same name) to the pi's home directory
• A destination path that is a file name (not a directory) will transfer the file with the same name to the pi's home directory
• A destination path that is a directory will transfer the file to the same directory on the pi (this will require calling mkdir on the pi before the transfer

If you would like to test your changes and functionality on the pi please send me a message on teams and I can provide you with login information.

• A destination path that is a file name (not a directory) will transfer the file with the same name to the pi's home directory

A little confused on what you meant by this. If the destination path is a file name is the bin file transferred to the pi's home directory or is a file on the computer with the same name transferred to the home directory?

[CameronBeneteau]

No need for home/username as the script can only transfer files within this directory. There will be a permission error if you try to transfer a file to a directory that isn't under home/username. For scp, it is assumed the destination directory is relative to /home/username.

i.e. sh cantransfer.sh test.txt username IP new-directory will transfer the file to home/username/new-directory/test.txt

• A destination path that is a file name (not a directory) will transfer the file with the same name to the pi's home directory

A little confused on what you meant by this. If the destination path is a file name is the bin file transferred to the pi's home directory or is a file on the computer with the same name transferred to the home directory?

Let's simplify and assume the file will not be renamed on transfer, so the destination path will always be a path.

The required behaviour will be reduced to the following:

1. sh cantransfer test.txt macformula xxx.xxx.xxx.xxx
   Transfers test.txt to home/macformula/test.txt

2. sh cantransfer test.txt macformula xxx.xxx.xxx.xxx random
   Transfers test.txt to home/macformula/random/test.txt

Please see #294 (comment) about home/username.

After testing the CAN flash transfer with the Pi, it should work as intended. Let me know if anything else is needed from me
