BleReader.Net

blereader.net

一个简单的包装器使用.NET从蓝牙LE设备读取制造商数据。

目前，它使用DBU和Bluez（使用Dotnet-Bluez）支持Linux。除了提供原始制造商数据外，它还为特定设备提供了分析数据（目前仅支持Ruuvitag）。

特征

• 读取Ruuvitag的数据
• 获取所有可用设备及其数据的列表（地址，姓名，制造商ID和制造商数据）

要求

• Linux系统带有5.50或更高版本的Linux系统

安装

作为Nuget软件包可用：

 dotnet add package BleReader.Net

用法

获取Ruuvitag数据：

 var adapterName = "hci0";
var scanDurationSeconds = 5;
var ruuviMacAddress = "12:34:56:78:90:AB";

IBleReader reader = new BleReader(new DotNetBlueZService());
await reader.ScanAsync(adapterName, scanDurationSeconds);
var ruuviTag = await reader.GetManufacturerDataAsync<RuuviTag>(ruuviMacAddress);
if (ruuviTag != null)
{
    var dataAsJson = JsonSerializer.Serialize(ruuviTag, new JsonSerializerOptions() { WriteIndented = true });
    Console.WriteLine($"Data: {dataAsJson}");
}
else
{
    Console.WriteLine("No RuuviTag found");
}

输出：

 Data: {
  "DataFormat": 5,
  "Humidity": 27.495,
  "Temperature": 18.1,
  "AirPressure": 1006.94,
  "AccelerationX": -0.004,
  "AccelerationY": -0.012,
  "AccelerationZ": 1.032,
  "BatteryVoltage": 2.881,
  "TxPower": 4,
  "MovementCounter": 184,
  "MeasurementSequenceNumber": 12774,
  "MacAddress": "12-34-56-78-90-AB"
}

获取所有已找到设备的信息：

 var adapterName = "hci0";
var scanDurationSeconds = 5;

IBleReader reader = new BleReader(new DotNetBlueZService());
await reader.ScanAsync(adapterName, scanDurationSeconds);
var deviceInfoList = await reader.GetAllDevicesAsync();

var firstDevice = deviceInfoList.FirstOrDefault();
if (firstDevice != null)
{
    var bytesAsString = BitConverter.ToString(firstDevice.ManufacturerData?.Data);
    Console.WriteLine($"Bluetooth device with address {firstDevice.Address} found");
    Console.WriteLine($"Manufacturer ID = {firstDevice.ManufacturerData?.Id}");
    Console.WriteLine($"Manufacturer data = {bytesAsString}");
}
else
{
    Console.WriteLine("No devices found");
}

输出：

 Bluetooth device with address 12:34:56:78:90:AB found
Manufacturer ID = 1177
Manufacturer data = 05-0E-24-2A-F6-C6-06-FF-FC-FF-F4-04-08-A0-36-B8-31-E6-12-34-56-78-90-AB
