Bluetooth Speakerphone question(s)

Not sure if this is the correct forum but here goes...

I bought a Motorola bluetooth speakerphone for use with my Android smartphone in the car... I paired them together without a problem and the speakerphone works nicely in the car... When I enter the car the speakerphone announces it has connected to my smartphone and tells me its battery charge level...

But here's my confusion...

Today when I entered my car I did NOT have my smartphone on me... Yet the bluetooth speakerphone still announced it had connected with my smartphone as I entered the car... Then about 30 seconds later I hear a beep as if it did not find the phone... How is the bluetooth speakerphone detecting my entry into the car when I don't have my smartphone on me???

That's eerie and creepy

Is there any reason it would power on when you enter the car? Is it close enough to be able to connect to your phone in the house/building even when the speakerphone is sitting in the car?

Yeah I thought the same... The car is in my driveway... Speakerphone in the house bedroom, maybe 30 feet away... What's the range of bluetooth?... I thought bluetooth was very short range wireless... Does the bluetooth speakerphone sense, or hear the car door being opened and shut and that triggers the connect message?

Most of those bluetooth devices advertise a range of around 30 feet. I haven't experimented with the real-world range myself, but it should be somewhere around there. It's certainly not impossible for them to sync at that range.

I'm assuming that you drove off a little ways and that's when it let you know that it lost the connection?

Now we just have to determine why it powered on when you got in your car

Correct... For the record, this device is a Motorola Roadster Bluetooth Car Kit... The cryptic instructions say the following:

The car kit automatically turns off when your phone is moved away from the car for more than 1 minute. When you return (open the car door), the car kit turns back on and reconnects to your phone.

Just did a quick google search on it. I can't find the exact mechanism, but like you said, somehow it detects when you open your car door and it automatically attempts to pair with your device again.

Wherever your phone was, it must have been close enough to pair with the speakerphone, even at that distance.

Neat!

Hmmmmm... Maybe it is programmed to "hear" the car door open and close to trigger a connect request to the phone??...

Someone suggested that in a review I just read. I guess it's possible. I don't know what the power requirements for listening for that would be. The device claims 3 weeks standby time, so whatever the method is for door-opening detection, it can't be too power-intensive.
