@surban what are your thoughts on this approach?

[surban]

I left you a few comments.

Also please make sure to always run "cargo +nightly fmt" and "cargo clippy" before submitting a PR.

@surban I made the changes except for three requests I responded with comments. Sorry for all the commits, I was running into an odd issue where git would say:

 ! [rejected]        118-Save-LE-Advertising-Reports -> 118-Save-LE-Advertising-Reports (non-fast-forward)
error: failed to push some refs to 'https://github.com/potto216/bluer'
hint: Updates were rejected because the tip of your current branch is behind
hint: its remote counterpart. Integrate the remote changes (e.g.
hint: 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

Even though I was the only one committing to the branch.

Thanks.

Feel free to send a separate PR if you want to add plain text logging.

Oh I see your point, I didn't realize the hex format isn't supported in standard JSON.

[surban]

You could try using JSON5 which seems to have hex support. But I don't know how good serde support is at the moment.
