The BPC1 is not directly supported from the iPad LCS app. You can still use the BPC1 in the LCS environment - using a Cab to control the power. Only the LCS app won't show the status.
The BPC1 and the AMC1 are two designs I wish we could forget. They use awkward key presses on the Cab's to activate, and the BPC1 is beyond complicated for most folks to connect up.
