to test bt link, program a pic to serout some data say "1,2,3,4 a,b,c,d" every second or so to the bt module. the baud from pic to module should match but the bt to pc link makes its own rate. I'm sure you found the com port created by the bt device through the SPP - serial port profile mode seen in bt settings on win8. on my device bt set up 2 com ports of which one works the link. with that you can try/check for the correct T and R connections at pic end.
I put hyperterm on my win8 just copy pasted 2 files
