Win7 and bluetooth
February 5, 2013
Hey guys. This one is more of a win7 problem and I'm hoping someone else with win7 maybe has played with the bluetooth modules you buy on ebay and might have solved this problem.
I've got a HC-06 unit and it works fine. I've had it paired and communicating with my arduino thanks to sketches and tips here.
However I found I had to modify the code so that the arduino would continually send a character to maintain connection. If the port is left idle it drops after 2-3 seconds.
I wasn't sure if it was the module at fault or my pc. So I connected with a terminal app from my galaxy and tested it. Everything was fine. No loss of connection after being idle for a couple minutes and I imagine inifinately or until my phone battery runs flat or disconnected.
Now I googled this and found that people have had problems with win7 and bluetooth peripherals(mice and such). I followed some suggestions as to settings in power management etc, but it made no difference and others had same experience.
Any ideas as to what win7 is doing here? I haven't had a reason to hate it yet.(I actually love win7) but this is peeving me a bit.
