# `Bluez.Variant`
[🔗](https://github.com/bbangert/bluez/blob/v0.1.0/lib/bluez/variant.ex#L1)

Unwraps `org.bluez` D-Bus property maps (as decoded by `rebus`) into plain
Elixir maps for `Bluez.Advert`.

rebus decodes an `a{sv}` dict to a list of `{key, {signature, value}}` and a
variant to `{signature, value}`. This module strips those wrappers, with two
special cases that are themselves nested dicts of byte arrays:

  * `ManufacturerData` (`a{qv}`): `[{company_id, {"ay", bytes}}]` → `%{company_id => binary}`
  * `ServiceData` (`a{sv}`): `[{uuid, {"ay", bytes}}]` → `%{uuid => binary}`

Pure and host-testable — this is the main parse seam between raw D-Bus wire
data and advert reconstruction.

# `unwrap_props`

```elixir
@spec unwrap_props([{String.t(), term()}]) :: %{optional(String.t()) => term()}
```

Unwrap a decoded `a{sv}` property list into a `%{name => value}` map.
