在UWP中获取已连接BluetoothLEDevice的RSSI,可以通过以下步骤实现:
string deviceId = "设备的标识符";
BluetoothLEDevice bluetoothDevice = await BluetoothLEDevice.FromIdAsync(deviceId);
var gattServicesResult = await bluetoothDevice.GetGattServicesAsync();
if (gattServicesResult.Status == BluetoothGattCommunicationStatus.Success)
{
// 成功获取到设备的Gatt服务列表
}
GattDeviceServicesResult gattServicesResult = await bluetoothDevice.GetGattServicesAsync();
if (gattServicesResult.Status == BluetoothGattCommunicationStatus.Success)
{
var services = gattServicesResult.Services;
foreach (var service in services)
{
if (service.Uuid == desiredServiceUuid)
{
var characteristicsResult = await service.GetCharacteristicsAsync();
if (characteristicsResult.Status == GattCommunicationStatus.Success)
{
var characteristics = characteristicsResult.Characteristics;
// 在特征列表中找到你想要的特征并处理
}
}
}
}
Guid desiredCharacteristicUuid = new Guid("特征的UUID");
var characteristicsResult = await service.GetCharacteristicsAsync();
if (characteristicsResult.Status == GattCommunicationStatus.Success)
{
var characteristics = characteristicsResult.Characteristics;
foreach (var characteristic in characteristics)
{
if (characteristic.Uuid == desiredCharacteristicUuid)
{
GattReadResult result = await characteristic.ReadValueAsync();
if (result.Status == GattCommunicationStatus.Success)
{
var reader = DataReader.FromBuffer(result.Value);
byte rssi = reader.ReadByte();
// 处理读取到的RSSI值
}
}
}
}
这样,你就可以在UWP应用程序中获取已连接BluetoothLEDevice的RSSI值了。
注意:上述代码仅为示例,实际使用时需要根据具体的设备和特征进行相应的调整。
