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 toolBLE Advertisement Builder
Compose BLE advertising payloads from flags, names, service UUIDs, service data, manufacturer data, and beacon templates, with live byte limits.
Open toolGATT UUID Lookup
Identify services and characteristics from 16-, 32-, and 128-bit UUIDs, including common vendor-defined values.
Open toolBLE UUID Generator & Converter
Generate 128-bit custom service and characteristic UUIDs, convert between 16-, 32-, and 128-bit forms, and copy byte arrays for firmware.
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 toolBluetooth HCI Log Viewer
Open Android btsnoop and Linux btmon captures in the browser and browse HCI commands, events, connections, and ATT traffic with decoded errors.
Open toolBLE Connection Parameter Validator
Validate connection interval, peripheral latency, and supervision timeout values against Bluetooth requirements.
Open toolBLE Throughput Calculator
Estimate ATT throughput from PHY, connection interval, MTU, data length, and event scheduling.
Open toolBLE Discovery Latency & Battery Estimator
Estimate how quickly a scanner discovers an advertiser from advertising and scan timing, and what the advertising settings cost in battery life.
Open toolBluetooth Assigned Numbers Explorer
Search company identifiers, advertising data types, appearance values, adopted services, and member UUIDs.
