(...) I should have made it more clear that all my BT remarks were in the context of use in the industrial or embedded spaces such as robotics where we get access to the hardware. Sure, millions of BT cell phones are shipping, but that's no help to (...) (19 years ago, 2-Jun-05, to lugnet.robotics)

I have watched this thread for a while, but not "joined in" as I am not personally familiar with implementing Bluetooth. However, I have a question about the assertion that Bluetooth necessarily requires high power consumption; How well do coin cell (...) (19 years ago, 3-Jun-05, to lugnet.robotics)

(...) My remarks were made comparing the power use of advertised BT chips vs 900-MHz and 2.4 GHz RF chip sets based on what was available a couple of years ago. To answer your question about headsets, I will speculate since I don't really know. But (...) (19 years ago, 3-Jun-05, to lugnet.robotics)

Bruce, 1. True, Bluetooth is embedded in a lot of cellphones. But cellphones is not the only device that carries Bluetooth, as you already know. However, SonyEricsson has created the ROB1, which is a Linux robot that is controlled by Bluetooth, (...) (19 years ago, 3-Jun-05, to lugnet.robotics)

(...) I'd love to have my cell phone give me status and feedback from my robots. BT isn't the only way to do this, of course, and using the cellular data capability of the phone would allow connecting from around the world, not just within 10 (...) (19 years ago, 3-Jun-05, to lugnet.robotics)

Bruce, 1. Yeah, SonyEricsson is very serious about their Linux robot 2. How else (other than Bluetooth) could you send data from your cellphone to your robot? IR isn't an ideal solution, since a lot of phones don't support it. 3. I created the (...) (19 years ago, 3-Jun-05, to lugnet.robotics)

(...) Use the data capability of the phone to set up their equivalent of an IP connection. On my TMobile phone this is painfully slow, under 100 kbits at best, often less than 50 kbits, even when literally next door to a cell. I did some tests with (...) (19 years ago, 3-Jun-05, to lugnet.robotics)

Bruce, 1. TMobile does have a flat rate for data at $19 /mo 2. Is there really interest anymore in RS-232 Bluetooth modules? I used to have a conact at BlueUnplugged.com and he was almost willing to give them away, because they weren't selling. 3. (...) (19 years ago, 5-Jun-05, to lugnet.robotics)
