use
Registers to use a given context and completes once the context has been used successfully.
Using a context will handle switches to/from BLE/WIFI internally.
Please be aware, that due to internal processes, if you call use for a SOContext, the contextsInUse may emit a new item with the new context already contained before this Completable completes. However, the SOContext is only able to take subscriptions / publish items after the use Method has completed.
Scheduler: The returned Completable will operate on the IO Scheduler.
Return
a Completable which completes once the context has been initialized successfully.
Parameters
context
the SOContext to use.
