Building a Cross-Platform BLE Client with Kotlin Multiplatform and Kable

Georg Dresler

Stop duplicating fragile Bluetooth code across mobile ecosystems. Transform chaotic BLE integrations into a stable, coroutine-powered codebase using Kotlin Multiplatform and Kable.

#1 about 4 min

The complexities of developing Bluetooth Low Energy applications

Frequent disconnects, platform differences, and unreliable state callbacks make managing Bluetooth functionality notoriously challenging for developers.

#2 about 5 min

Core architecture and building blocks of Bluetooth Low Energy

The foundational architecture of the protocol relies on centrally coordinated clients, broadcasting peripherals, unique services, and distinct characteristics.

#3 about 3 min

Managing asynchronous state in robust Bluetooth connections

Discovering nearby devices, negotiating authentication, and serializing concurrent read and write requests demand precise asynchronous state management.

#4 about 4 min

Handling asynchronous operations with native Kotlin coroutines

Suspending functions and flows abstract asynchronous callbacks into sequential code while coroutine scopes safely manage connection cancellation and cleanup.

#5 about 5 min

Building portable Bluetooth logic using Kotlin multiplatform

The onion architecture pattern isolates platform-specific implementations to outer layers while preserving core domain and business logic for cross-platform reuse.

#6 about 4 min

Abstracting platform-specific Bluetooth APIs using the Kable library

Integrating a unified multiplatform library eliminates disparate platform quirks by mapping standard operations natively to coroutine flows and suspending functions.

#7 about 5 min

Controlling a selected Bluetooth peripheral via live demo

Filtering device advertisements and writing continuous characteristic updates enables functional real-time control of hardware peripherals from a shared codebase.

#8 about 2 min

Platform constraints on concurrent peripheral device connections

Operating systems heavily dictate the maximum number of concurrent peripheral connections a single central leader can securely maintain.
