# Efento SDK The **Efento SDK** enables the development of custom applications that interact with Efento BLE loggers. The SDK provides functions for scanning and connecting to Efento loggers, allowing you to read measurements from the device memory or configure and modify the settings. This **Kotlin Multiplatform library** supports both Android and iOS, leveraging Kotlin coroutines for asynchronous operations. It is designed for multiplatform projects targeting Kotlin/Android and Kotlin/Native (iOS). You can download the SDK, along with [documentation](https://efento.github.io/Efento-Bluetooth-SDK/), manuals, and usage examples, from the [**Efento GitHub**](https://github.com/efento/Efento-Bluetooth-SDK). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
