Hi all,
I am having problems connecting VR mode and Ketai Bluetooth connectivity in Android mode. (Win10; Porcessing 3.3.5; Android 6.0.1; Samsung S5 Neo). Independently code for Ketai bluetooth works:
import processing.vr.*;
import android.content.Intent;
import android.os.Bundle;
import ketai.net.bluetooth.*;
import ketai.ui.*;
//import ketai.net.*;
PFont fontMy;
KetaiBluetooth bt;
String info = "";
//********************************************************************
// The following code is required to enable bluetooth at startup.
//********************************************************************
void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
bt = new KetaiBluetooth(this);
println("Creating KetaiBluetooth");
}
void onActivityResult(int requestCode, int resultCode, Intent data) {
bt.onActivityResult(requestCode, resultCode, data);
}
//********************************************************************
void setup() {
//fullScreen(STEREO);
size(displayWidth, displayHeight, P3D);
//start listening for BT connections and connect to a device.
bt.start();
bt.connectDevice("00:14:03:06:37:0E");
//font size
fontMy = createFont("SansSerif", 40);
textFont(fontMy);
}
void calculate() {
}
void draw() {
background(150);
translate(width/2, height/2);
noStroke();
// Green box, Y axis
pushMatrix();
translate(0, 200, 0);
fill(0, 255, 0);
box(100);
popMatrix();
// text from Bluetooth
// info = "abc\ndef"; //debugging
text(info, 20, 104);
}
void onBluetoothDataEvent(String who, byte[] data) {
//received
info = new String(data);
}
Everything connects nicely to my HC-05 and gets the info, and prints it next to the green box.
But then I decide to add VR functionality, and everything goes wrong. So I un-comment
//fullScreen(STEREO);
and comment
size(displayWidth, displayHeight, P3D);, and change Android mode from "App" to "VR". The build is successful, but the app crashes and I get the following error:
java.lang.NullPointerException: Attempt to invoke virtual method 'boolean ketai.net.bluetooth.KetaiBluetooth.start()' on a null object reference at processing.test.test2.test2.setup(test2.java:63) at processing.core.PApplet.handleDraw(Unknown Source) at processing.vr.PSurfaceVR$AndroidVRStereoRenderer.onDrawEye(Unknown Source) at com.google.vr.sdk.base.CardboardViewNativeImpl.nativeOnDrawFrame(Native Method) at com.google.vr.sdk.base.CardboardViewNativeImpl.access$2500(CardboardViewNativeImpl.java:53) at com.google.vr.sdk.base.CardboardViewNativeImpl$RendererHelper.onDrawFrame(CardboardViewNativeImpl.java:569) at com.google.vr.ndk.base.GvrSurfaceView$GLThread.guardedRun(GvrSurfaceView.java:1643) at com.google.vr.ndk.base.GvrSurfaceView$GLThread.run(GvrSurfaceView.java:1324) handleDraw() called before finishing
The VR-code will work nicely, if I comment the bt.start();and bt.connectDevice("00:14:03:06:37:0E");
Is it normal? Can Ketai work with In-built Processing Arduino VR Mode at all?
Thanks!
