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.

1M vs. 2M vs. Coded PHY: Choosing the Right BLE PHY for Throughput
2M PHY is faster, but it doesn’t necessarily double your throughput. Here’s what actually happens and how to choose the right PHY for your use case.

The Fundamentals of BLE Throughput: What’s Possible and Why
BLE throughput isn’t a single number, it depends on how your connection is structured and configured. This article breaks down what’s actually possible and why.

How Much BLE Security Does Your Device Actually Need?
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…

Understanding BLE Security Boundaries: What It Protects and What It Doesn’t
BLE encryption and authenticated pairing secure over-the-air communication, but they don’t protect data once it reaches your app or cloud. Learn where BLE security stops and when you need TLS, end-to-end encryption, and user authentication.

Understanding BLE Connections: How to Choose Advertising, Scanning, and Connection Parameters
Choosing the right BLE connection parameters directly impacts discovery speed, reliability, and battery life. This article explains how advertising, scanning, and connection intervals work together and how to tune them for real-world performance.
