Slightly off-topic, but it's a question people here might know better than anyone on the planet.
I'm after a Class 1, bluetooth v2 (must also do v1.2) adapter for serial ports (DB9). Needs SPP profile, no other profiles required, but they might be useful. Baud rates from 1200 to as high as possible, and must include
57600).It must be powered entirely from a standard PC computer's port, with no unusual wiring or external supply. Having trawled Google many times looking for something to bypass all the software nonsense trying to get something that will install W98 drivers, I decided it must NOT have a need for any drivers at all. I thought I'd found a good answer, then found that the config program MUST have .net framework! Pretty stupid for a device someone might want to run from OpenBSD, or DOS, no? :)
Has anyone got a nice definitive sort of answer for this? I'm prepared to spend up to $100 (£50, and cheaper would be cool...) for a device that can allow me to operate exactly as if I'd just plugged a cable to a DB9, with no strange wiring or power requirements, no driver requirements, and ALL config, if any is needed, easily done by communicating with it by text commands written in a terminal emulator.
Please don't point me to links and general possibilities, I can easily find too many of those on Google to choose easily, and still find nasty gotchas like .net requirements that are not openly declared. I'm asking here hoping for answers from people who use these things, and already know firsthand what works best and most easily, and is completely independent from the host operating system.
