When a Bluetooth module drops connections in the field, draws 3 mA above spec in sleep, or fails certification on the 2nd channel of the 40-channel DTM sweep, the difference…

Building a BLE tag asset tracking system is not about choosing the right tag. It is about the infrastructure that receives, filters, transports, and stores the data from hundreds or…

Most Bluetooth Beacon projects fail not because of bad hardware but because of firmware that burns through batteries in weeks instead of years, crashes under RF interference, or silently stops…

Why Layout Decides Whether Your Module Works A Bluetooth module is only as good as the PCB it sits on. You can buy a pre-certified module with -95 dBm sensitivity…

Why Motion Sensing Belongs on Every Asset Tag Most BLE tag deployments track location, but location alone doesn't tell you whether a pallet was dropped, a crate tipped over, or…

Beacon Advertising Packet Design & Payload Optimization Every Bluetooth beacon lives or dies by its advertising packet. The packet is the beacon's voice — a 31-byte whisper on legacy BLE,…

Bluetooth Module Production Testing & Mass Production Calibration Every Bluetooth module shipped to a customer passes through a production test line. The difference between a module that works "most of…

Why Tamper Detection Matters for Asset Tags BLE asset tags are increasingly deployed on high-value equipment, pharmaceutical cold-chain packaging, and rental assets where unauthorized removal triggers financial or compliance risk.…

Indoor positioning remains one of the highest-value applications for Bluetooth beacons. GPS signals attenuate below concrete ceilings, leaving beacon-based systems as the primary indoor alternative. This article compares the two…

The Generic Attribute Profile (GATT) layer defines how Bluetooth Low Energy devices expose data to clients. For engineers integrating Bluetooth modules into products, the GATT service architecture directly determines application…
