When bluetooth devices are in use, antennas in these receivers are transmitters and receivers at the same time, right? So, like with every other trans-receivers or just receivers, there should be some way to indicate the strength of the signal? Like bars, or something.. Just like they were pinging each other comparing the result and displaying average result. e At 1 meter it reads: x dBm or mW (I googled these units - I don't know they are actually used to measure signal strength), at 2m it's a bit less and with every meter further from the device the signal is getting weaker up until it looses connection, let's say it is 100 meters.. When two bluetooth devices are paired, do they constantly exchange some data? If they do, and I suppose they do, the application could include some kind of 'double check' of the signal strength.. Taking that you can measure the strength of the signal with the accuracy of 1 meter you should end up with 100 different reading and each reading would represent different distance.. Later, user would have choose, the in the application, what kind of area he's in, before calculating distance between BT devices. Taking that you can measure the strength of the signal with the accuracy of 1 meter you should end up with 100 different reading and each reading would represent different distance.. Bluetooth is typically used to connect cell phones and PDAs to hands-free devices such as headsets and speakerphones, but it also can be used to connect those devices to computers and MP3 players.. And there should be a device to measure that What I think you have to do is measure the strength of the signal at different distances, i.. I'm no expert, I haven't got any technical background whatsoever, but this is how I see it working.. What I mean is that two devices would be communicating and comparing their readings.

That's how phone's signal indicator works, isn't it? What I think you have to do is measure the strength of the signal at different distances, i.. That's how phone's signal indicator works, isn't it? Damn I can't sleep What if he took these readings in three different areas, let's say: one in the open area without any obstacles, 2nd in the urban area, and last one indoors.. Then you'll have to create some kind of script that would read that data and translate into numbers, so for example x dBm=1 meter, y dBm=2m, z dBm=25m and so on.. It's not perfect but it would narrow down the margin of mistake, wouldn't it? Other thing I thought about.. Then you'll have to create some kind of script that would read that data and translate into numbers, so for example x dBm=1 meter, y dBm=2m, z dBm=25m and so on.. In general, applications that depend on direct serial port access are legacy applications or, perhaps, the debugging components of other applications. e828bfe731
