PVK documentation is in the latest versions of the PETROG and PetrogLite manuals. Documentation can be downloaded here.


The PVK connects to PETROG or PetrogLite via your local network. The connection is the same if the PVK and PETROG/PetrogLite are on the same machine, wired or wirelessly connected. This means that they will need permission to connect through your network Firewall security. So you will need to grant permission for them to connect. If you update either PETROG, PetrogLite or PVK software then that permission will need to be granted again. So please ensure you know how to do this, or discuss with your network security administrator.

The applications use tethering. On connection the PVK will look for an application that is listening for a connection and they will exchange a security protocol to identify one another. They will not tether with any other applications and only exchange messages between one another within the local network.
