When your app won’t connect to a BLE peripheral, you need to know whether the problem is in your code or the device itself. LightBlue is a BLE central app that lets you test the peripheral independently. If LightBlue connects and your app doesn’t, the issue is in your app code.
This guide walks through common scenarios: connection failures, read/write issues, and no...
If you’re a medical device engineer, you’ve likely noticed the ground shifting beneath your feet. With the FDA’s latest cybersecurity guidance released i...
When you’re building a Bluetooth Low Energy product, one of the earliest and most impactful decisions you’ll make is architectural: how will your device connect and communicate? Will it maintain a persistent connection or advertise periodically, connecting only when needed?
This choice fundamentally shapes your product’s power consumption, responsiveness, and abilit...
LightBlue is a BLE development tool we built to solve problems we kept running into, the friction that slows down every BLE project. We share it freely with the community because these challenges show up everywhere: hardware that doesn’t exist yet, bugs that only surface sometimes, security that breaks at the worst moment, and assumptions about performance that don’t survive ...
It’s a common story in Core Bluetooth development: you call scanForPeripherals, and…. nothing. Or the device shows up sometimes but not others. Or it works perfectly in the foreground but disappears when your app backgrounds. Or it behaves completely differently than the same peripheral does on Android.
Scanning for BLE peripherals on iOS isn’t just about calling a ...
