BLE UART vs Busy Bluetooth
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
BLE UART
This tool facilitates iOS program development by connecting to low-power Bluetooth devices. It allows users to read data from serial devices via Bluetooth and send data to the serial port for debugging purposes.
- Connects to low-power Bluetooth devices
- Reads data from RXD serial port
- Sends data to TXD serial port
- Facilitates iOS program development
- Debugging tool for serial devices

During iOS program development, you may need to read and write serial devices. This tool connects to low-power Bluetooth devices (BT24, etc.) through the low-power Bluetooth interface on iPhone and iPad, displays the data received by RXD, and sends TXD data to the serial port, thus achieving the goal of debugging the device.
Busy Bluetooth
This tool helps developers and engineers efficiently debug Bluetooth Low Energy devices. It allows real-time scanning, detailed inspection of device data, and recording of all interactions for repeatable debugging. Export logs in various formats for comprehensive analysis.
- Real-time BLE device scanning
- Filter devices by various parameters
- Inspect device details and advertisement data
- Record connection events, reads, writes, and notifications
- View payloads in hex, text, and decoded formats
- Export logs as JSON/CSV or debugging packages

Busy Bluetooth is a BLE scanner and debugging tool for developers, hardware engineers, and IoT device testing. Use it to discover nearby Bluetooth LE devices, inspect RSSI, advertised services, UUIDs, manufacturer data, and connection state. After connecting, you can track reads, writes, and notifications in a timeline built for repeatable debugging. Key features: • Scan Bluetooth LE devices in real time • Filter by name, UUID, service, manufacturer data, connectability, and RSSI • Inspect device details, advertisement data, services, and characteristic UUIDs • Record connection events, reads, writes, and notifications • View payloads as hex, text, and structured decoded data • Export JSON / CSV logs or generate a debugging case package • Useful for BLE peripheral development, IoT troubleshooting, hardware testing, and field validation Busy Bluetooth keeps the core BLE workflow clear: scan, connect, inspect, record, and export.
