Signal Hub turns Bluetooth Low Energy testing into repeatable, automated workflows. Instead of tapping through the same connect–read–write steps by hand, you run a multi-step BLE workflow on real hardware with a single tap — right from your iPhone or iPad. Built for firmware developers, hardware engineers, and IoT makers tired of slow, manual, error-prone BLE testing. AUTOMATE YOUR BLE TESTING - Workflow runner: execute multi-step sequences — scan, connect, read, write, subscribe — automatically on real devices. - Logic & control flow: branch on results, loop, and retry flaky steps with backoff so one failure doesn't end the run. - Start in seconds: built-in templates run a real example instantly — some need no hardware at all. ALSO A COMPLETE BLE TOOLKIT - Scan and discover nearby devices with live signal info and filters. - Inspect GATT services, characteristics, and descriptors. - Read & write in HEX, ASCII, or UTF-8, and subscribe to live notifications. Build it once. Run it anywhere. Terms of Service: https://getsignalhub.app/terms-of-service
