Mavlink byte by byte

Hello. I want to send byte by byte my Mavlink message (or hexadecimal by hexa). Do you know how to do this ? I know this page Serialization · MAVLink Developer Guide and this Messages (common) · MAVLink Developer Guide but problems: i don’t know how to do the signature, the checksum and even parameters are not obvious. If you know example of this it could be great!
Thank you.

Have you seen this thread?

When data is displayed in “hexadecimal”, this is just one way us humans like to see our data.

There are some rare and inefficient protocols which convert hexadecimal ASCII characters into binary to send but I’m pretty sure this isn’t what you want to do.

You want to send data. Let the microcontrollers and computers deal with the bits.
