RSL Central vs IDFA & Device Stats

An easy-to-use app to get started with onsemi Bluetooth Low Energy wireless microcontrollers and periphery devices. RSL Central scans for and establishes a Bluetooth Low Energy connection with onsemi Bluetooth Low Energy wireless microcontrollers. The app displays fields such as measured battery level, voltage, current, LED status, push button status, or others depending on the onsemi wireless microcontroller and configuration.

Device Inspector gives you a complete, real-time view of your iPhone or iPad's hidden configuration — the same data that ad networks, analytics SDKs, and diagnostic tools read every time you open an app. WHAT YOU CAN SEE • Advertising Identifier (IDFA) — your device's unique ad ID, shown clearly with its current status (zeroed-out when tracking is off) • App Tracking Transparency (ATT) status — Authorized, Denied, Restricted, or Not Determined • Device model, OS version, build number, and kernel info • Screen resolution, scale factor, and display metrics • Locale, region, preferred languages, and timezone • Network interface details (Wi-Fi, Cellular, VPN) • Carrier name, MCC/MNC, and radio access technology • Battery level, charging state, and low-power mode • Processor count, memory, and thermal state • Push notification permission status • And more — updated every time you pull to refresh WHY IT'S USEFUL If you work in mobile advertising, analytics, or app development, knowing exactly what your device reports is essential for debugging attribution, verifying ATT consent flows, or checking that your privacy controls are working correctly. Device Inspector shows you precisely what the OS exposes — no guessing. PRIVACY FIRST Everything you see stays on your device. No data is collected, no network requests are made (other than loading ads via AdMob), and no account is required. The app is open source. NOTES • IDFA reads as all-zeros until you grant App Tracking Transparency permission. • The iOS Simulator always returns zeros for IDFA — use a real device. • Tap any row to copy its value to the clipboard. • Use the search bar to filter across all fields instantly.
