FastBle is an Android Bluetooth Low Energy development framework that simplifies BLE operations like scanning, filtering, connecting, reading, writing, and notifications. It supports multi-device connections, auto-reconnection, RSSI reading, and MTU configuration through a fluent Java API.

Use cases

• scan and filter BLE devices by name, MAC, or UUID on Android
• connect to multiple BLE peripherals simultaneously
• read and write BLE characteristics with notifications and indications
• implement auto-reconnection for BLE devices with retry logic
• read signal strength (RSSI) and set MTU for BLE connections
• build an Android app that talks to BLE sensors or wearables

When to choose

• you are building an Android app in Java that communicates with BLE devices
• you need multi-device BLE connections with simple callback-based APIs
• you want built-in reconnection, timeouts, and scan filtering without writing raw BluetoothGatt code

When to avoid

• you are developing for iOS, desktop, or non-Android platforms
• you need Kotlin-first or coroutine/Flow-based BLE APIs
• your project requires BLE features outside the Android BLE stack, such as Bluetooth Classic
