⚠️ Important: A "passing" status means that the package compiled successfully with Nerves for this system. It does not guarantee that the package will work correctly at runtime or that all features are compatible with Nerves.
The compatibility test only verifies that:
- The package and its dependencies can be fetched from Hex.pm
- All dependencies are from Hex (no git or path dependencies)
- The firmware can be built successfully
If you believe a status is incorrect or have additional compatibility information, please open an issue (the title and template are pre-filled for this package).
