Hello,
I am trying to connect meter using optical probe through otg. So what should be below line:
IGXMedia media = mDevice.getMedia();

Sir,
How to get IGXMedia from USBSerialPort?
I am trying this one : public class AndroidSerialMedia implements IGXMedia but its Overridden method "properties" does not working as its need javax.swing.JFrame parent which is not present in android.
Can u please send me source code for Android to connect using OTG?

Hi,
The Gurux Android project setup and run successfully in below Android version 15. But in android 15 after Association view confirm pop up it will auto close the app due to ANR. Please suggest.

Hi Sir,
Below error msg are coming in android log :
