When I compare with a real compass I see different values.

There is no "calibrate" so I cannot get the true north. How can that be corrected?

In order to check whether the user needs to recalibrate the compass or not, it would be nice to get some information about the accuracy of the measurements.

It seems likenewHeading.headingAccuracy on iOS and public void onAccuracyChanged(Sensor sensor, int accuracy) on Android are the ways to get the accuracy. This could for instance be sent as a second parameter in the event handler callback: RNSimpleCompass.start(degree_update_rate, (degree, accuracy) => { ...

A problem is that "accuracy" is not the same thing on iOS and Android... Android uses four integer values, while on iOS uses floating point values that might be negative.

An alternative to getting the accuracy value is to dispatch an event when the compass is giving an invalid value, and will probably need calibration. This is when the accuracy is negative on iOS or 0 on Android.

What do you think?

Working on a side project with react native that uses this project. I'm new to working with RN so apologies if the answer is obvious.

After following the setup instructions (running react-native-simple-compass --save and react-native link) I encounter the following error when importing RNSimpleCompass:

undefined is not an object (evaluating 'RNSimpleCompass.start')

I'm using React Native 0.49.3 with ViroReact. Has anyone else encountered this issue?

Module RNSimpleCompass requires main queue setup since it overrides init but doesn't implement requiresMainQueueSetup. In a future release React Native will default to initializing all native modules on a background thread unless explicitly opted-out of.

No podspec found for react-native-simple-compass in ../node_modules/react-native-simple-compass

The example code under the Usage section simply doesn't log to the console

Hi,

thank you for this package, it worked well on react 0.59, but on react 0.60.4 i have this error when I archive with xcode :

React/RCTBridgeModule.h' file not found

Do you have any idea how i can fix this ? i have been struggling with it for days, this package is vital for my app.

Thanks !
