Include headers for NimBLE GAP & GATT services

[tcbennun]

Not absolutely essential, but the functions in these headers make setting up BLE applications a lot easier!

Yeah, i agree. I would need it too. Would be awesome to see it soon in crates.io

@tcbennun How u did go around? Im a newbie in Rust until this moment i could set up a lot for a simple nimble scanner except these includes.

@JannesBrands I'm using my own fork of esp-idf-sys which includes this change. See the docs for how to set up your Cargo.toml to grab certain dependencies from places other than crates.io.

Ahh thank u. I already saw that, but sometimes I'm a little lost to find something in the rust docs and make sure it's the right haha.

I totally missed this for the last release.
Until it's released, you can use the master branch or use the new extra esp-idf components feature to add an additional C header to generate bindings with.
