BLE Buddy gives developers, testers, and curious people a native way to inspect Bluetooth Low Energy devices. Scan in real time, connect to a device, browse its GATT tree, and work with characteristics without reaching for a command-line tool.

What you can inspect

  • Real-time device discovery with signal strength indicators
  • Services, characteristics, descriptors, and live notifications
  • Read and write values in hex, ASCII, or decimal
  • RSSI graphs with min, max, and average signal strength
  • Security audit view for readable, writable, and notifiable characteristics
  • Smart decoding for common device types, plus a terminal for direct communication

Useful for

  • Developers building or debugging BLE peripherals
  • QA teams testing Bluetooth connectivity and signal quality
  • Security researchers, students, makers, and hardware tinkerers
