Always-Connected vs. Dynamic BLE: Which Strategy Fits Your Product?
Should your BLE device stay connected at all times or only link up when needed? We break down the pros, cons, and use cases for always-connected and dynamic BLE to help you make a confident architectural decision early in development.
Scanning for Peripherals on iOS Core Bluetooth
iOS BLE scanning doesn’t always work the way you expect. This article breaks down how Core Bluetooth actually discovers devices, why peripherals sometimes don’t show up, and how to build reliable scanning flows that work in the real world.
Why Your iOS BLE Scan Returns No Results (And How to Fix It)
Your iOS BLE scan returns no results and you can’t figure out why. This article walks through the most common causes of empty Core Bluetooth scans, from permission issues and state handling to iOS-specific scanning behaviors, and shows you how…
Why Your BLE Scan Returns No Results on Android
BLE scans on Android can fail silently, leaving you with an empty list and no clear reason why. This guide walks through the common causes, from permissions and filters to Android quirks, and how to systematically debug them.
Building a Reliable Android BLE Operation Queue
Unreliable reads, writes, and callbacks in Android BLE usually come down to one missing piece, a proper operation queue. Learn how to build a simple, thread-safe queuing system that ensures your BLE operations execute cleanly, one at a time.
