Continuously report temperature - No sensor reported

[paul-matthews]

Using the code snippet for Continuously reporting temperature sensor, no ambient temperature sensor is connected. However reading a single temperature value works fine. Is this library registering the driver for the Bmx280 on the board, because the sample doesn't cover it.

Repro steps:

1) Copy code snippet into onCreate. 2) Run activity on a Pi 3 (with working other functions)

Expected:

3) Observe logging of temperature sensor

Actual:

3) Observed logging only includes: "I/SensorManager: DYNS Register dynamic sensor callback"

• No events triggered into the SensorEventListener instance

On further inspection (attempting to use the getDefaultSensor() ) no sensors exist.

It seems the snippet you linked to is missing a call to registerTemperatureSensor(). For now, please refer to the Activity code in the Bmx280 driver sample, which demonstrates the same use case.

@plattysoft Not quite a duplicate (at least I don't think so), I think @paul-matthews issue is the code snippet is missing a call to registerTemperatureSensor(), so the sensor never actually becomes available.
