Bhai jaan, I was able to connect my Vgate OBD2 as shown earlier to work, atlast!!
Here are the snapshots
Torque shorque or OBD Doc isn't working. I used "SZ Viewer" instead. They claim the app is specifically for Suzuki vehicles, and it worked. Although only Engine and PS (Power Steering) pages display data as Wagon R doesn't have other things like AT, 4WD etc.
