I am a complete beginner with VTScada Light, and I am looking to connect a bluetooth device and display data using this software. The device I am using is a combustible gas sensor. What is the best way to accomplish this?

Could you be more specific ? Does the gas sensor have bluetooth capability ? We use Endress Hauser FMR-20 radars that have bluetooth capability, so you can log in to check trends or do a device setup. Anyhow, I am a bit confused as to what you are asking. I'd love to see if I could help, but want to know more about what it is you need.
