Universal BLE vs deepdig.dev

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

deepdig is a free toolbox of network diagnostics built for sysadmins, DevOps engineers and hosting operators — the checks you run every day, faster and more detailed, with no account and no ads. Enter a domain, IP or paste raw data. Checks run in parallel on our servers and results stream in live, each finding graded by severity with a plain-English explanation of why it matters. TOOLS • DNS diagnostics — records, delegation and glue consistency, full DNSSEC chain validation from the root, propagation across 18 public resolvers, and a hop-by-hop recursion trace • SSL/TLS — certificate chain, expiry, hostname match, trust, protocol versions, HSTS • WHOIS — registrar, dates, EPP status codes for domains; RIR allocation, ASN and abuse contacts for IPs • Mail tester — SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI, MX reachability and STARTTLS • Email header analyzer — paste a raw email, get the Received chain as a timed hop-by-hop trace with SPF/DKIM/DMARC verdicts • DNSBL / blacklists — check IPs and domains against major blocklists, Spamhaus included • HTTP headers — security headers, redirect chain, cookie flags, server fingerprint • HTTP/3 — ALPN negotiation, Alt-Svc advertisement and CDN detection • IP info — ASN, announced prefix, rDNS, country and hosting classification • Certificate Transparency log search • Subnet/CIDR calculator and a password generator WATCHES — GET NOTIFIED WHEN THINGS CHANGE Put a domain or IP on watch and deepdig re-checks it for you. You get a push notification only when something actually changes: a certificate crossing 14, 7 or 1 day to expiry (and a recovery notice when it renews), a new blacklist listing or a delisting, or a changed DNS record set. No noise, no daily digests — alerts only on real transitions. BUILT THE WAY YOU'D WANT IT • Results stream in as each check completes — no spinners • Every run is saved as a shareable permalink snapshot • History and side-by-side comparison for any target • Share a URL or domain from any app to open the right tool prefilled • Dark mode that follows your system • No account, no ads, no tracking, no analytics. Free. deepdig is the mobile companion to deepdig.dev — same engine, same results, in your pocket.
