@2hire/react-native-bleintsdk

React Native bridge for BLEIntSDK

Installation

npm install @2hire/react-native-bleintsdk

Android setup

Permissions

Add the service dependency in your app/AndroidManifest.xml

<config-file parent="/manifest/application" target="AndroidManifest.xml">
    <service android:enabled="true" android:name="io.twohire.bleintsdk.bluetooth.BluetoothLeService" />
 </config-file>

Building setup

Since the core Android dependency is available through JitPack it needs to be added to your repos.

// platforms/android/app/repositories.gradle
ext.repos = {
    // ...
    maven { url 'https://jitpack.io' }
}

For more info on requirements and permissions see more on the Android package here

Usage

Setup a new session

Before creating a session with a vehicle, a server session must be created using start_offline_session endpoint.

Create a BLEIntSDK Client instance with data received from the endpoint. See errors for other error codes.

import * as SDK from "@2hire/react-native-bleintsdk";

// ...

const commandsHistory: string[] = [];

// data received from start_offline_session endpoint
const accessDataToken = "session_token";
const publicKey = "board_public_key";
const commands: SDK.Commands = {
  start: "start_command_payload",
  stop: "stop_command_payload",
  end_session: "end_session_command_payload",
};

try {
  const result = await SDK.sessionSetup(accessDataToken, commands, publicKey);

  console.log(result); // true
} catch (e) {
  if (e.code === "invalid_data") {
    // data supplied is not correct. e.g. wrong format?
  }
}

Connect to a vehicle

Connect to a board and start the session. See errors for other error codes.

import * as SDK from "@2hire/react-native-bleintsdk";

// ...

// board mac address is received from start_offline_session endpoint
const boardMacAddress = "mac_address";

try {
  // connect to vehicle using `boardMacAddress`
  const result = await SDK.connect(boardMacAddress);

  // save base64 result.payload command response
  commandsHistory.push(result.payload);

  console.log(result); // { success: true, payload: "efab2331..." }
} catch (e) {
  if (e.code === "invalid_session") {
    // session is not valid. e.g. call server o get a new one
  }
}

Send a command to a vehicle

Available commands are Start and Stop. See errors for other error codes.

import * as SDK from "@2hire/react-native-bleintsdk";

// ...

try {
  const result = await SDK.sendCommand("start");

  // save base64 result.payload command response
  commandsHistory.push(result.payload)

  console.log(result); // { success: true, payload: "efab2331..." }
} catch (e) {
  if (e.code === "timeout") {
    // command timed out. e.g. retry command
  }
}

End a session

End the board session and clear the client instance. After ending a board session all payloads received must be then sent back to the server using end_offline_session. See errors for other error codes.

import * as SDK from "@2hire/react-native-bleintsdk";

// ...

try {
  const result = await SDK.endSession();

  // save base64 result.payload command response
  commandsHistory.push(result.payload);

  console.log(result); // { success: true, payload: "efab2331..." }

  // endServerSession(commandsHistory)
} catch (e) {
  if (e.code === "timeout") {
    // command timed out. e.g. retry command
  }
}
