Not sure if this is the right place for this kind of question, but I thought I'd give it a shot.
I am going to buy a new Android smartphone soon and it will have bluetooth 4.0. I mainly use bluetooth to connect to my Toyota in-dash enTune system, so it is a voice and data bluetooth connection.
I also have an interest in using the new FitBit personal exercise tracking device. Their new model is bluetooth 4.0 so instead of having to connect it to your computer to download the fitness data, it communicates with an app on your Smartphone continuously using the new bluetooth 4.0 low power standard.
Here is my question....does bluetooth 4.0 allow multiple devices to communicate with the phone? In other words, while I don't really care if my FitBit is actually communicating with my phone while I am driving my car, I don't want to have to manually connect or disconnect bluetooth profiles multiple times per day when I get in my car.
Likewise, if I am walking around the office and the my Fitbit is communicating with my phone, when I get in my car I want my Toyota enTune in-dash to work without turning off my Fitbit connection and connecting to my car every time.
Does anyone know? Will this all happen fluidly and without my intervention? Thanks!
