I saw this in the Neves Livebook when no sensor is connected.

This happens because we initialize the sensor in handle_continue. The error followed by {:ok, pid} result is a little confusing from the library user perspective, but I guess it is a matter of our design decision.

If we initialize the sensor in init callback not in handle_continue, we can return :error in case something goes wrong in the sensor initialization but then caller process would need to wait until the whole initialization gets completed.

To me personally from users perspective, I prefer to return {:error, reason} over always return {:ok, pid} unless initialization is painfully slow.

• Maybe it is OK and acceptable as a feature in favor of quick initialization? 🤔
• Maybe we can at least raise descriptive custom error message instead of the generic match error

That value was added before #21.
