wireless communication between z1 and unity

THETA Media Unity Development

Hi! I am trying to wirelessly control theta z1 in my Unity app. At the very beginning, I tried the HttpWebRequest class in c# and the script looks like this:

public class ThetaWifiStreaming : MonoBehaviour {

	public static string ToString(string cmd) {
		var sb = new StringBuilder();
		sb.Append("{");
		sb.Append("\"name\": \"");
		sb.Append(cmd);
		sb.Append("\", \"parameters\": {");
		sb.Append("}}");
		return sb.ToString();
	}

	static void start() {

		var command = ToString("camera.takePicture");
		var postBytes = Encoding.Default.GetBytes(command);
		string url = "http://192.168.12.21:80/osc/commands/execute";
		string username = "THETAYN10106522";
		string password = "10106522";
		HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
		request.Credentials = new NetworkCredential(username, password);
		Console.WriteLine(new NetworkCredential(username, password));

		request.Method = "POST";
		request.Timeout = (int)(5 * 1000f);
		request.ContentType = "application/json;charset=utf-8";
		request.ContentLength = postBytes.Length;

		Stream reqStream = request.GetRequestStream();
		reqStream.Write(postBytes, 0, postBytes.Length);
		reqStream.Close();
		Console.WriteLine("post done");

		HttpWebResponse response = (HttpWebResponse)request.GetResponse();
		Console.WriteLine((int)response.StatusCode);
		Console.WriteLine("response done");
	}
}

This works well if I copy and paste the main body of this script and run it as a new ordinary c# console app. But in unity, it will be stuck at the post done sentence and cannot get the response.

I was thinking this as an issue of HttpWebRequest and switched to the UnityWebrequest class. The script looks like this:

public class ThetaWifiStreaming : MonoBehaviour {

   void Start() {
      StartCoroutine(post());
   }

   IEnumerator post() {
      /* info */
      var command = ToString("camera.takePicture");
      var postBytes = Encoding.Default.GetBytes(command);
      string url = "http://192.168.12.21:80/osc/commands/execute";
      string username = "THETAYN10106522";
      string password = "10106522";
      var authorization = authenticate(username, password);

      /* post */
      var request = new UnityWebRequest(url, "POST");
      byte[] bodyRaw = Encoding.UTF8.GetBytes(command.ToString());
      request.uploadHandler = (UploadHandler)new UploadHandlerRaw(bodyRaw);
      request.downloadHandler = (DownloadHandler)new DownloadHandlerBuffer();
      request.SetRequestHeader("Content-Type", "application/json;charset=utf-8");
      request.SetRequestHeader("Authorization", authorization);
      yield return request.SendWebRequest();
      Debug.Log("Status Code: " + request.responseCode);
  }

  string ToString(string cmd) {
      var sb = new StringBuilder();
      sb.Append("{");
      sb.Append("\"name\": \"");
      sb.Append(cmd);
      sb.Append("\", \"parameters\": {");
      sb.Append("}}");
      return sb.ToString();
  }

  string authenticate(string username, string password) {
     byte[] credentialBuffer = new UTF8Encoding().GetBytes(username + ":" + password);
     var auth = "Basic " + System.Convert.ToBase64String(credentialBuffer);
     return auth;
  }
}

This script however always returns statuscode 401.

Would anybody gives me some suggestions on how to do it? Thanks!
