How to Discover Services and Characteristics on iOS Core Bluetooth
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.
How to Use the centralManager didDiscover Delegate in iOS Core Bluetooth
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.
BLE Throughput Optimization FAQ: Common Questions Answered
BLE throughput optimization depends on decisions across every layer of the stack. This FAQ answers the most common BLE speed and data transfer questions, from PHY selection and DLE to ATT MTU, connection intervals, and transfer methods.
BLE Transfer Methods and Application Design for Throughput
Even with the BLE stack configured correctly, application-layer decisions can still limit throughput. Learn how transfer methods, transmit pipeline management, and payload segmentation impact BLE data transfer performance.
BLE Connection Interval and Peripheral Latency: How to Configure for Throughput
BLE connection interval and peripheral latency determine how often devices get a chance to transmit data. Learn how connection parameters affect throughput on iOS, Android, and proprietary BLE devices.
BLE ATT MTU, DLE, and Message Sizing: The Biggest Levers for BLE Throughput
Enabling DLE alone won’t maximize BLE throughput. Learn how ATT MTU, payload sizing, and packet fragmentation work together to determine BLE data transfer performance.
