As part of our mission to make Bluetooth development more accessible and help product developers, we’re releasing a tool we’ve relied on internally for years—now available publicly to the entire Bluetooth engineering community.
The Argenox BLE Advertising Tool helps you build, decode, and optimize Bluetooth Low Energy advertising packets with immediate, visual feedback. It takes the guesswork out of advertising design, letting you see exactly how your data is structured, how much space it consumes, and what tradeoffs you’re making—before you ever flash firmware.
Whether you’re working on a battery-powered sensor, a provisioning flow, or a production-scale product, this tool helps you ship cleaner, more efficient BLE advertisements.
What the BLE Advertising Tool Does
- Decode existing BLE advertising payloads into a human-readable format
- Build custom advertising packets field-by-field
- See exact byte usage and remaining space in real time
- Validate advertising structures against the BLE specification
- Quickly experiment with different payload layouts to optimize data density
Key Features
- Live Advertising Packet Builder
Construct advertising payloads using standard AD types such as:- Flags
- Complete / Shortened Local Name
- Service UUIDs (16-bit, 32-bit, 128-bit)
- Manufacturer Specific Data
- Service Data
- Real-Time Size Calculation
Instantly see how many bytes each field consumes and how much room remains within the 31-byte advertising limit (or extended advertising where applicable). - Packet Decoder
Paste in raw advertising data and get a clean, structured breakdown of each AD element. - Optimization-Focused Design
Designed specifically to help engineers:- Minimize advertising payload size
- Maximize useful data per packet
- Avoid common formatting mistakes
- Spec-Aligned Output
Advertising structures are generated to align with the Bluetooth Core Specification, helping reduce interoperability issues during bring-up and testing. - No Setup Required
Runs directly in the browser—no installs, no accounts, no dependencies.
Future
We’re working on improving the tool with some more features and more fields, but if you have any feedback, you can send an email to. feedback [a][t] argenox.com
