2 - Eject Expoīut maybe you’re like us and you need Bluetooth and you need it now. Canny is the best way to get the features you care about prioritized on the Expo roadmap. There is no Bluetooth API for Expo yet, but you can still build a Bluetooth app with Expo.Īs soon as we discovered this, we made a feature request on Canny for an Expo Bluetooth API. But lo and behold our Google search left us empty handed.

It only made sense to turn to them as they provide a ton of useful JavaScript APIs that interact with a mobile device. Troubleshooting 1 - IntroductionĪs many developers have, Expo was the first place we looked for a Bluetooth API. Here’s a quick overview of what we’ll cover today: Overviewġ.

In the second part, we’ll explore a simple Bluetooth app, and in the third, we’ll re-build the same app using Expo’s future Bluetooth API. In this first part, we focus on ejecting Expo and setting up React Native to interface with the Bluetooth capabilities of the phone. This guide is Part One of a planned three-part series. (Before we begin, you should know that this method will only work for BLE devices and not Bluetooth classic devices.) Part 1 - Ejecting Expo and Bluetooth

Here’s a quick guide to help you accomplish all of this with React Native and Expo. At Penta Medical, we use React Native and various libraries to connect to our Bluetooth Low Energy (BLE) device without having to write much native code. Which means you have to connect to a Bluetooth-enabled device.

Let’s say you’re starting your next project, and your app is Bluetooth-based.
