Key takeaways for nRF Blinky
Where is it heading?
- v3.2.0 added Android 12 compliance (Jan 2025) — shows active maintenance for OS standards.
- Persistent 'Mixed' sentiment regarding connectivity — core functionality remains unreliable for a segment of users.
The SWOT
- Official Nordic Semiconductor backing
- Open-source reference code on GitHub
- Extreme simplicity for 'Hello World' testing
- Zero-cost ecosystem support tool
- Add basic data logging to compete with Bluefruit Connect
- Integrate OTA/DFU firmware update capabilities
- Expand documentation for Android 12+ permission edge cases

Bottom line
nRF Blinky is a successful 'first-contact' tool for the Nordic ecosystem, but it is currently hampered by connectivity regressions. To maintain its position as the default starter app, it must fix core stability issues on Android and consider adding basic telemetry features to prevent immediate user migration to Adafruit or Punch Through tools.
