You can use a Paradyme on any RTCM3.1 network. It's easy to use the second serial port on the second connector to input RTK corrections. Digi has a BT device that will work. We have a BT/WIFI device with will work. Or you can use a generic BT adapter.
With BlueTooth Lefebure's app is the simplest way to use it. So for an Android phone his app works with generic BT, Digi's BT, and our device. For Apple, right now Digi's BT device is an option as they have an iOS app for it. Our device can also be used with just a WIFI hotspot.

Paradymes are finicky about their calculations. So if a physical base is nearby the corrections from a virtual caster will be fairly good and it should not loose its fix too often. When the physical bases are all far away then Paradymes tend to lose their "RTK fixed" accuracy and go to "RTK float". So with a virtual network like Digifarm's , physical base distances can affect it.
