HelloBlue: Bluetooth Debugger
Scanner, Inspector & Manager
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
HelloBlue turns your iPhone or iPad into a Bluetooth Low Energy (BLE) debugging tool. Scan nearby devices, connect in a tap, explore every service and characteristic, send data, and watch the traffic live, all in one clean app.
Built for firmware engineers, IoT developers, testers, and hardware makers who need to inspect and talk to BLE devices quickly.
KEY FEATURES
- Scan and connect
Discover nearby BLE devices with live signal strength (RSSI). Search by name or UUID, sort by name or signal, rename devices, and reconnect to recent devices automatically.
- Services and characteristics
Browse every GATT service and characteristic. Read values as hex and text, write data, and subscribe to notifications. Give services and characteristics names that make sense to you.
- Send data your way
Send in Hex, String, or JSON. Save frequently used commands as quick texts and resend them with one tap.
- Live operation logs
Watch reads, writes, notifications, and errors stream in real time from any screen. Filter entries and turn auto-scroll on or off.
- Session history
Every session and automation run is saved. Review past logs, rename them, export them to share with your team, or delete what you no longer need.
- Automation workflows
Chain connect, write, delay, and loop steps into reusable flows. Set message intervals and repeat counts, and choose whether each step stops or continues on failure.
- Location history
HelloBlue records where a device was each time it connects, making it easier to find again.
- iPhone and iPad
Works on both, with layouts designed for each screen.
Bluetooth must be turned on, and HelloBlue needs Bluetooth permission to scan and connect. Location history requires location permission. Some features depend on the services and characteristics your device provides.

Ratings & Reviews
HelloBlue is the new name for BLE Debugger.
- New name and icon: BLE Debugger is now HelloBlue, with a fresh app icon that also supports dark and tinted Home Screen styles.
- More reliable connecting: the Connect button now waits while a device is connecting, so repeated taps no longer start duplicate connection attempts.
- Smoother log panel: dragging the log panel up and down is faster and more fluid.
- Bug fixes and stability improvements.
