Rom flashing + Bluetooth Pairs

view story

http://forum.xda-developers.com – If one is to flash a ROM over their old rom (lets say a new nightly over an older nightly), does that have any effect on the bluetooth pairings that were made? Would my phone still recognize those pairings or ask me again to configure/set them up after the new ROM is flashed overtop? Same goes for other devices such as a bluetooth speaker. Would that speaker need to be configured again to find my phone and such or would there be no changes? (HowTos)
