BLE Tag Direction Finding with AoA/AoD: Bluetooth 5.1 Angle Estimation
A BLE Tag becomes far more useful when you can tell not just how far it is, but which direction. This article explains how a BLE Tag uses Bluetooth 5.1…
Beacon and Smartphone App Interaction: Triggering, Background Limits, and Privacy
A Beacon is only useful when a phone notices it. This article covers how a Beacon talks to a smartphone app: advertising formats, distance triggers, platform background limits, and the…
Bluetooth Module Production Testing and Calibration: From TX/RX to Yield Traceability
Bluetooth modules power countless wireless products, yet the chip alone is not enough—every module that ships must be individually verified on the production line. This article explains how a Bluetooth…
BLE Tag Roaming Across Gateways: Seamless Handoff and Cross-Gateway Continuity
A BLE Tag is rarely stationary. As it moves through a warehouse, hospital, or campus, it silently crosses the coverage of one gateway and enters another. Done well, this handoff…
Beacon Installation and Signal Calibration: Mounting, Materials, and RSSI-to-Distance Tuning
A Beacon deployment is only as accurate as the surface it is mounted on and the calibration behind it. Two identical Beacon units can report wildly different distances if one…
Bluetooth Module RF Testing and Certification: What Pre-Certified Really Saves You
A Bluetooth module promises "certified" on the datasheet, but what does that actually cover? Understanding RF testing and certification is how you avoid a six-figure surprise at the end of…
BLE Tag Advertising Tuning: Balancing Broadcast Interval, Power, and Battery Life
A BLE Tag is only as good as the advertising policy that drives it. Set the interval too slow and the phone misses it; set the transmit power too high…
Connecting Beacon Data to IoT Platforms: Integration Patterns and Real Use Cases
A Beacon is only useful when its broadcasts reach the systems that act on them. The tiny packets leaving a Beacon every few hundred milliseconds carry location, telemetry, or asset…
Bluetooth Protocol Stack Architecture: Why a Bluetooth Module Hides the Complexity
A Bluetooth module is far more than a radio on a PCB. Underneath the metal shield sits a complete Bluetooth Low Energy protocol stack that turns raw RF into services,…
BLE Tag Environmental Sensing and Data Reporting
A BLE Tag is not only a locator — bolt a sensor onto it and it becomes a wireless sensor node that reports temperature, humidity, motion, or light without any…
