Android's ScanFilter API lets you narrow BLE scan results to the devices that matter most. Learn how to filter by service UUID, device name, manufacturer data, and more while optimizing scan behavior for faster, more reliable discovery.

Learn how to perform a BLE scan on Android using Kotlin, from configuring permissions and BluetoothLeScanner to displaying nearby devices and managing scan results across Android versions.

Learn how to subscribe to notifications and indications in iOS Core Bluetooth using setNotifyValue, handle notification state changes, and receive characteristic updates from BLE peripherals without polling.

A successful BLE connection is only the beginning. Learn how to discover services and characteristics on iOS Core Bluetooth, navigate a peripheral's GATT table, and prepare for reading, writing, and subscribing to characteristic values.

BLE issues often trace back to the advertising packet, but it's hard to diagnose what you can't see. Learn how to verify BLE advertisement data with LightBlue and confirm that your device is broadcasting the service UUIDs, manufacturer data, and connection settings your app expects.

The centralManager didDiscover delegate is where BLE scanning results become actionable. Learn what Core Bluetooth provides through CBPeripheral, advertisementData, and RSSI, and how to use that information to identify and manage devices before connecting.

When integration testing breaks down, it’s not always obvious whether the problem lives in your firmware or somewhere else. This guide shows you how to debug BLE firmware with LightBlue step by step, from advertising and connections to GATT discovery, notifications, writes, and pairing.

FDA’s expanding TAP Program signals a shift toward continuous oversight for connected medical devices. That shift changes what teams need to design for: not just functionality, but architecture that can prove performance, traceability, and control across the product lifecycle.

Should you test against a simulated peripheral or real hardware? This article breaks down when LightBlue Virtual Devices are useful and when relying on them can hide integration issues you need to catch.

Not every BLE device needs maximum security. A fitness tracker, smart lock, and medical device face very different risks. This article walks through a practical framework to help you determine the right level of BLE security for your product based on regulation, data sensitivity, threat model, and user experience tradeoffs.
