UniversalBle Explorer vs Your Beacon Simulator

UniversalBle Explorer is an open-source developer tool for discovering, connecting to and debugging Bluetooth Low Energy devices. Built on the universal_ble Flutter plugin, it offers a consistent experience across all platforms. SCAN & DISCOVER • Real-time scanning with a prominent scan button and a Start Scan prompt when no devices are found • Filter by service UUIDs, name prefix or manufacturer data, with saved presets that persist between sessions • Search devices by name or company name, resolved from Bluetooth SIG company identifiers • Sort by RSSI, last seen or name • View RSSI, the last advertisement and a live advertisement list that flashes as new packets arrive • Scanning continues while you inspect a device • Inspect devices already connected at system level on supported platforms CONNECT • One-tap connect and disconnect with live connection state • Optional autoConnect for automatic reconnection • Multiple simultaneous connections SERVICES & CHARACTERISTICS • Full GATT discovery with clear, human-readable output • Favorite services first, system services last • Property filter chips for read, write, notify, indicate and more • Text search by characteristic UUID, ignoring case and hyphens • Previous/next navigation between characteristics • Copy the complete service layout from the panel header READ, WRITE & SUBSCRIBE • Read characteristic values on demand • Write with or without response • Subscribe to notifications and indications, individually or for all at once • Live values in the log with timestamps GATT SERVER • Create, edit and manage GATT server profiles with services and characteristics • Run a peripheral server with advertising • Add or remove services at runtime • Import and export profiles as JSON DEVICE FINGERPRINT • Capture a complete fingerprint in one tap: 60 seconds of consolidated advertisements, discovered services, all readable values and a rolling-ID check after reconnecting • Copy the full report or stop the capture at any time LOGS & DIAGNOSTICS • Add custom log entries and clear individual entries • Auto-scroll to the newest entry, with a persisted toggle • Characteristic UUIDs included on read, write and error entries • Copy advertisements with an optional RSSI column • Detailed error codes and a configurable operation timeout POWER USER TOOLS • Command queue: Global, Per Device, Auto or None • Request a larger MTU for higher throughput • Pair and unpair devices with live pairing state • Guided permission flow and Bluetooth availability indicator BUILT FOR DEVELOPERS Whether you are building a BLE product, testing hardware, validating firmware or learning Bluetooth Low Energy, UniversalBle Explorer gives you the visibility and control you need. It is free, open source and built on the universal_ble plugin.

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.
