Make it easier to use UUIDs with the plugin API #105

Closed ghost closed 7 years ago

ghost commented 8 years ago

Problem:

The plugin API can be hard to use, and people my not wish to use an add-on API like EasyBLE or Bleat.

Specifically, the plugin API use handles to services, characteristics and descriptors. There is no built-in support for mapping UUIDs to these handles. This can make it hard to work with the plugin API.

Function readAllServiceData provides some support, but services, characteristics and descriptors are stored in arrays, which do not provide mappings. Manually iterating over the arrays is needed to find UUIDs and corresponding handles.

Suggestion:

Return a dictionary from readAllServiceData (or make a new function) that provides mappings.

Also investigate if the deviceHandle/deviceObject could be stored in a structure. Now the developer has to track this manually.

Example of structure:

deviceInfo
    deviceObject/deviceHandle
    services (dictionary with mapping service UUID --> service object)
        characteristics (dictionary with mapping characteristic UUID --> characteristic object)
            descriptors (dictionary with mapping descriptor UUID --> descriptor object)

Something similar to this has been implemented in BLE plugin version 2.0.0. Closing this issue.
