【报Bug】使用uni.getBLEDeviceCharacteristics无法获取设备特征值，API响应成功但是返回结果为空数组

示例代码：

递归获取设备服务
_getCharacteristics(serviceId: string) {
const deviceId = this._deviceId;
const maxAttempts = 10;
let attempt = 0;

const tryGetCharacteristics = (): Promise<any[]> => {  
  return new Promise((resolve, reject) => {  
    uni.getBLEDeviceCharacteristics({  
      deviceId,  
      serviceId,  
      success(res: any) {  
        if (res.characteristics && res.characteristics.length > 0) {  
          resolve(res.characteristics);  
        } else if (attempt < maxAttempts - 1) {  
          attempt++;  
          setTimeout(() => {  
            tryGetCharacteristics().then(resolve).catch(reject);  
          }, 1000);  
        } else {  
          resolve(res.characteristics);  
        }  
      },  
      fail(e: any) {  
        if (attempt < maxAttempts - 1) {  
          attempt++;  
          setTimeout(() => {  
            tryGetCharacteristics().then(resolve).catch(reject);  
          }, 1000);  
        } else {  
          reject(new BluetoothError(e));  
        }  
      },  
    });  
  });  
};  

return tryGetCharacteristics();

预期结果：

{
"characteristics": [
{
"uuid": "0000FF01-0000-1000-8000-00805F9B34FB",
"properties": {
"read": false,
"write": true,
"notify": false,
"indicate": false
}
},
{
"uuid": "0000FF02-0000-1000-8000-00805F9B34FB",
"properties": {
"read": true,
"write": false,
"notify": true,
"indicate": false
}
}
],
"errMsg": "getBLEDeviceCharacteristics:ok"
}

实际结果：

{
"characteristics": [],
"errMsg": "getBLEDeviceCharacteristics:ok"
}
