What you can do

Test BLE, your way

  • Scan & connect — discover nearby BLE devices, sorted by signal strength, and connect with a tap.
  • Inspect GATT — browse services and characteristics; read / write / notify values in hex or text.
  • Quick commands — save labelled send macros for the payloads you use most.
  • UART console — talk to Nordic UART and similar serial-over-BLE devices, with an exportable transcript.
  • Saved devices — name peripherals and remember their preferred characteristics for instant reconnect.

Automate with Lua

  • Write scripts in a built-in editor with syntax highlighting and autocomplete.
  • Drive devices in code: scan, connect, read, write, and react to notifications.
  • Build live on-screen panels — buttons, labels, and readouts that update as your device responds.
  • Helpers for hex, bytes, JSON, timers, and per-script key/value storage.
  • Learn with a Getting Started guide and a searchable in-app Lua API reference.

Private by design

  • No accounts, no analytics, no tracking, no ads.
  • Everything you create stays on your device.
  • Optional iCloud sync keeps your saved devices and scripts in your own iCloud.
