Use Case: EFB Apps via WiFi

WXStar broadcasts all weather data in GDL90 format on the Starlink Mini’s local WiFi network. Any GDL90-compatible EFB app picks it up automatically once connected.

Compatible apps:

Scenario A — Aviation Plan (Always-On)

With a Starlink Aviation 300 MPH, 450 MPH, or Jet plan, the Starlink Mini stays connected throughout the flight. WXStar broadcasts GDL90 continuously. No additional app needed — it just works. Connect your iPad/phone to the Starlink Mini WiFi and configure your EFB app to receive GDL90 (see app-specific pages above for screenshots).

Scenario B — Standby / Travel Plan + WXStar iOS App

With a Standby or Travel plan, WXStar periodically reconnects the Starlink Mini to fetch fresh weather data. During the brief offline interval the WiFi disappears, which would cause a gap in your EFB display.

The free WXStar iOS app bridges this gap:

• GDL90 relay: while Starlink is connected, the app forwards the GDL90 stream to your EFB app.
• Heartbeat during reconnects: when Starlink briefly goes offline, the app sends a minimal GDL90 heartbeat (with GPS from your device) so your EFB stays connected.
• Automatic: runs in the background once configured — no in-flight interaction needed.
• Free: no cost, no in-app purchases.

The result: a continuous EFB experience on a plan at ~10 EUR/month instead of $250+/month.
Requirements: iPhone or iPad on a recent iOS, connected to the Starlink Mini WiFi network.

Setup: Install the app → connect your device to the Starlink Mini WiFi → open the app (auto-detects WXStar) → in your EFB app, set GDL90 source to the address/port shown in the WXStar app.
