No sure where this question should be posted but....

Installed a Crossfire nano rx to TBS powercube w/ FPvision layer. The nano BST SCL and BST SDA are both connected to vision layer BST port. I can see my crossfire rssi on osd, working great.

The problem is, when the crossfire is connected via BST port to FPvision layer, it eliminates all voltage/mah reading, everything reads zero concerning batt. I also get the "batt det fail" alert at startup. When I disconnect the BST port jumper to nano, the voltage comes back. So how do I connect crossfire rssi and still see my voltage in osd? Can I have the best of both worlds?
