Universal BLE vs Your Beacon Simulator

Universal BLE is an open-source developer tool for exploring and testing Bluetooth Low Energy (BLE) devices. It empowers developers, engineers, and hobbyists to discover, connect, and debug BLE devices with a consistent cross-platform experience. Key Features Device Discovery Real-time scanning — Discover nearby BLE devices with live results; scanning continues when you open a device's detail screen Flexible filters — Filter by service UUIDs, name prefix, or manufacturer data (comma- or newline-separated) Saved filter presets — Save, rename, and reuse filter combinations; filters persist across app sessions Search — Search devices by name or by company name (resolved from manufacturer data via Bluetooth company identifiers) Sort options — Sort the device list by RSSI, last seen, or name Company identification — Show company name from manufacturer data using the Bluetooth SIG company identifier list RSSI and advertisements — View signal strength (RSSI), last advertisement (name, RSSI, timestamp), and a list of received ads that flashes on new advertisements System devices — On supported platforms, view and connect to devices already connected at the system level (with optional service filter) Connection Management Connect and disconnect — Connect to and disconnect from BLE peripherals with one tap Auto-reconnect — Optional auto-connect for reconnection when a device becomes available again Connection state — Real-time connection state updates Multiple connections — Support for multiple simultaneous device connections Service & Characteristic Exploration GATT discovery — Discover all services and characteristics on connected devices with detailed, human-readable formatting Favorite services — Mark services as favorites; they appear first in the list (system services last) Property filters — Filter characteristics by property (read, write, notify, indicate, etc.) with visual filter chips Navigation — Previous/next buttons to move between characteristics without collapsing the list Copy services — Copy the full discovered GATT layout (e.g. for documentation or debugging) from the Services panel header Data Operations Read — Read characteristic values on demand Write — Write data to characteristics (with or without response) Subscribe — Subscribe to notifications/indications per characteristic or "subscribe to all" for notifiable characteristics Live updates — Incoming values are shown in the logs with timestamps; clear or copy the full log Pairing & Security Pair and unpair — Initiate pairing and unpair devices when supported Pairing state — Monitor pairing state changes in real time Advanced & Developer Options MTU — Request a larger MTU (e.g. 247) for better throughput where supported Command queue — Choose queue type in the drawer: Global (single queue), Per Device, or None (parallel) Configurable timeout — Set operation timeout (e.g. 10 seconds) for all BLE operations Logs — Operation log with copy-all and per-entry clear; comprehensive error handling with detailed codes UUID formats — Accepts common UUID string formats (e.g. with or without hyphens) UI & Cross-Platform Responsive layout — Adapts to mobile, tablet, and desktop (e.g. breakpoints at 600px and 1000px) Bluetooth status — Bluetooth availability icon with tooltip (tap on mobile to see state) Permissions — Guided permission flow where required (e.g. location for BLE on Android); re-checks on app resume Cross-platform — Built with the universal_ble plugin for consistent behavior across supported platforms Perfect For Developers building BLE-enabled applications Engineers testing and debugging BLE devices Hobbyists exploring IoT and smart device capabilities Students learning about Bluetooth Low Energy technology QA teams validating BLE device functionality

Your Beacon Simulator is a powerful, multi-platform developer utility designed to simulate, broadcast, and discover virtual beacons. Built entirely in modern SwiftUI, it eliminates the need for physical hardware when testing location-based applications, indoor navigation systems, or proximity triggers. Whether you are configuring virtual beacons on the go or managing complex proximity layouts from your desk, the app leverages your device's native Bluetooth stack to deliver a seamless, hardware-free testing environment. KEY FEATURES • Virtual Beacon Broadcasting Group multiple configurations under a single Proximity UUID. Enjoy full control over Major/Minor IDs and calibrate Measured TX Power on the fly. Export and share your configurations instantly. • Advanced Discovery & Scanning Target specific Proximity UUIDs to actively scan your environment. The real-time dashboard categorizes signals (Immediate, Near, Far, Unknown) and provides deep-dive metrics including raw RSSI, estimated distance in meters, and last-seen timestamps. • Apple Watch Companion* Control active broadcasts and discovery scans right from your wrist. Enjoy real-time state mirroring, tactical haptic feedback, and a tailored wearable UI. • Background Monitoring* Utilize CoreLocation to track UUID regions even when the app is minimized. Get rich local notifications and pinpoint the exact Major/Minor ID that triggered an event. • Session-Based Live Logging Eliminate guesswork with a real-time event ledger. Track exactly when your app initiates scanning, catches a new beacon, or marks a missing device as stale. OPEN SOURCE Proudly open-source under the AGPL-3.0 license.

Background Monitoring is available exclusively on iOS and iPadOS.
