BT itself is not overly complicated. Bargain basement BT chips, which is what everyone ends up using to save pennies, are full of bugs that have to be worked around. Of the various BT stacks out there, only a few are actually good, and the good ones get to charge appropriate licensing fees, meaning that they aren't in wide use. When you combine randChip with randBtStack, the end result is not necessarily a quality product. The poor engineers who have to work with this combination end up resorting to sending reset commands to their chip in an attempt to get the damn thing working.
