Bug fixes and reliability improvements: • Fixed sharing exported GATT, automation, security, and text logs, which could fail to open on some devices • Fixed device connection status not updating correctly after reconnecting • Hardened DFU firmware updates with stronger trust verification and more reliable background handling for Silicon Labs and STM32WB targets
Scan nearby BLE devices, inspect GATT, decode advertising, and test OTA.
Debug Bluetooth Low Energy (BLE) devices from Android. BleSmith is a BLE GATT debugger for firmware and embedded engineers: scan nearby devices, inspect GATT services, decode advertising data, monitor RSSI, and test compatible DFU and OTA workflows from one workbench. BLE Scanner and Advertisement Analyzer • Discover nearby Bluetooth LE devices and advertisers in real time • Filter by device name, MAC address, service UUID, and RSSI • Inspect raw advertising data, manufacturer data, TX power, PHY, and intervals • Decode iBeacon, Eddystone, and AltBeacon packets • Scan BLE 5 extended and coded PHY advertisements on supported devices GATT Explorer and Client • Browse services, characteristics, and descriptors • Read and write values in common developer formats • Subscribe to notifications and indications • Adjust MTU, PHY, and connection priority • Monitor signal strength and characteristic values live Packet Decoder and Protocol Tools • Build declarative or scripted decoders for custom BLE payloads • Preview decoded fields from live device data • Import definitions from Protobuf or C structs • Export Wireshark Lua dissectors, C headers, and JSON RSSI Monitoring, Logging, and Automation • Plot RSSI and telemetry in real time • Test GATT throughput and UART-style data streams • Run repeatable multi-step BLE test sequences • Manage multiple device connections • Export sessions as CSV, JSON, or PCAPNG • Import Bluetooth snoop logs for Wireshark analysis BLE Peripheral and GATT Server • Turn your Android phone into a BLE peripheral • Start GATT server templates for Heart Rate, Battery, Device Information, Nordic UART, and HID • Clone a discovered GATT structure for app and firmware testing DFU and OTA Firmware Updates • Run Nordic legacy and secure DFU • Update Zephyr and Mynewt devices with MCUmgr/SMP • Use generic BLE OTA workflows for compatible firmware • Test standard BLE devices built with ESP32, nRF52, Arduino-compatible boards, sensors, wearables, and IoT hardware Built for BLE Development • Vendor-neutral tools for firmware bring-up, mobile integration, and QA • Focused dark interface for long debugging sessions • BLE project data and saved workspace files stay on your device An account is required to use BleSmith. Bluetooth and location permissions are used for nearby-device discovery as required by Android and device compatibility.
