Newbie to Bluetooth
Posts: n/a I'm new to Bluetooth and want to clarify a few things. I hope someone could help  1. Does Bluetooth connect to devices separated by, say, a wall? 2. Some Bluetooth USB adapters claim they have a range of 100m! If I had one of these in my bedroom could I connect to any Bluetooth enabled devices in my househo, including upstairs and downstairs devices (assuming they are are within 100m radius)?! Thanks   Responses to "Newbie to Bluetooth"

If I had one of these in my bedroom I could to any Bluetooth enabled devices in my house, including upstairs and downstairs devices (assuming 10m devices are within 10 meters and 100m devices are within 100m) your range is limited to the range of the lowest powered device of the pair.

Just ordinary brink I guess. So should be fine. Just ordered one. Thanks!

I read some time ago that people could talk to each other anonymously through Bluetooth! That true?

That true? You can only connect to those devices that you discover that you know the passcode to or are left "open" to allow unsecured connections. Generally speaking you're probably not going to find too many of the latter. Cheers TC

Posts: n/a Re: Newbie to Bluetooth Often the number of attempts is not specified - what's specified is the TIMEthe device is left open when pairing. Open devices just connect with/or without code for pairing. Many Audio Headsets use a fixed code, such as 0000. How do you set a passcode, it's in the options for the drivers on the PC, or on the device itself, or fixed. > How many attempts could I make at guessing the passcode before it gets > 'locked'? > > How do I set my passcode?

My Sony Ericsson T68i always prompts for a passcode. The passcode is whatever you want it to be you just have to have the same one on both ends of the connection. Perhaps your phone is set the same way? Cheers TC
