Bluetooth for React Native

⚠️ Requires: Neurosity OS v16+, to be released in January 2023

Adding the Bluetooth transport for React Native requires the react-native-ble-manager library. Install the library and set up the permission as per their documentation before moving to the next step.

Before

import { Notion, WebBluetoothTransport } from "@neurosity/sdk";

export const neurosity = new Notion({
  autoSelectDevice: true
});

After

import { Neurosity, ReactNativeTransport } from "@neurosity/sdk";
import { NativeModules, NativeEventEmitter, Platform } from "react-native";
import BleManager from "react-native-ble-manager";

export const neurosity = new Neurosity({
  autoSelectDevice: true,
  bluetoothTransport: new ReactNativeTransport({
    BleManager,
    bleManagerEmitter: new NativeEventEmitter(NativeModules.BleManager),
    platform: Platform.OS
  }),
  streamingMode: "bluetooth-with-wifi-fallback"
});

When using Bluetooth, there are 2 streaming modes you can choose from:

• wifi-with-bluetooth-fallback
• bluetooth-with-wifi-fallback

Bluetooth Connection State

const { bluetooth } = neurosity;

bluetooth.connection().subscribe((connection) => {
  console.log(`Bluetooth connected is ${connection}`);
});

The following connection states are possible:

enum BLUETOOTH_CONNECTION {
  SCANNING = "scanning",
  CONNECTED = "connected",
  CONNECTING = "connecting",
  DISCONNECTING = "disconnecting",
  DISCONNECTED = "disconnected"
}

Auto Connect

By default, the Web Bluetooth transport will attempt to auto connect to the selected device. To disable this behavior, set the autoConnect transport option to false:

import { Neurosity, ReactNativeTransport } from "@neurosity/sdk";
import { NativeModules, NativeEventEmitter, Platform } from "react-native";
import BleManager from "react-native-ble-manager";

export const neurosity = new Neurosity({
  autoSelectDevice: true,
  bluetoothTransport: new ReactNativeTransport({
    autoConnect: false
    BleManager,
    bleManagerEmitter: new NativeEventEmitter(NativeModules.BleManager),
    platform: Platform.OS
  }),
  streamingMode: "bluetooth-with-wifi-fallback"
});

It is also possible to enable or disable this behavior at runtime:

const { bluetooth } = neurosity;

bluetooth.enableAutoConnect(true);

// or

bluetooth.enableAutoConnect(false);
