Android bluetooth communication access modes?

When开发者_开发技巧 I check the bluetooth developer page, it states very clearly that the android api supports the establishment of RFcomm channels. Now, is this mode exclussive for android or does android also support HCI or Bnep (more specifically l2cap)? (Or am I completely wrong and all three are completely different entities?)

Anywho, thank for any help ~Aedon

RFcomm is a higher level protocol than HCI or Bnep, there aren't Android APIs for managing these lower-level protocols.
