Hi circuit
have you tried to send directly a PM to Sigmacom? the App is still present on the PlayStore, I have checked it right now. You only need a valid google account, an invitation by the developer (Sigmacom) and some cents to buy and install it.
I use that app daily.....It is not a nice start. it is almost perfect.
But, I think the bluetooth module will be integrated by Justin in the CA itself sooner or later.
