Practical tools for Bluetooth engineering
Decode protocol data, identify Bluetooth values, validate connection behavior, and turn low-level output into clear engineering decisions.
Move from raw data to a clear diagnosis
Each tool turns low-level Bluetooth data into structured, actionable output and connects the result to relevant SimpleBLE guidance.
BLE Advertisement Decoder
Decode BLE advertising payloads into AD structures, manufacturer data, service data, company identifiers, and recognized beacon formats.
Open toolGATT UUID Lookup
Identify services and characteristics from 16-, 32-, and 128-bit UUIDs, including common vendor-defined values.
Open toolGATT Characteristic Value Decoder
Decode common adopted GATT characteristic values into typed fields, flags, units, and readable measurements.
Open toolBluetooth Address & OUI Lookup
Classify public and random Bluetooth addresses, inspect privacy subtypes, and identify eligible IEEE assignments.
Open toolBluetooth ATT & HCI Error Decoder
Identify standardized ATT errors and HCI Controller status codes by hexadecimal value, decimal value, or name.
Open toolBLE Connection Parameter Validator
