有人做过IrDA底层开发吗

我想使用IrDA 的Ultra协议发送ObEX，有人做过吗，介绍一下经验。J2ME是否可以接收处理基于Ultra协议发送的ObEX
关于ObEX over Ultra

6.5 Appendix 3: Using OBEX over IrDA Ultra-Lite (Connectionless use)
OBEX is constructed to take advantage of the benefits of a connection oriented transport, for instance by
exchanging capabilities and version information just once in the Connect packet. However, for transfers of
small objects OBEX can be useful in a connectionless environment, such as that provided by the IrDA
UltraLite proposals. A number of issues arise and are discussed in the following sections.
6.5.1 assuring reliable delivery
· CRCs
· Out of band feedback (visual/audible)
6.5.2 how long to wait for a response
· In the range of 3 to 5 seconds, optionally totally at application discretion.
· Allow responseless operation for Put (unidirectional link)
6.5.3 exchanging capabilities
· Put all version/capability items in headers, allow them in Put/Get packets.
6.5.4 condensing operations into a minimal exchange
· streaming multiple small objects in one packet.
· No Connect or Disconnect - just go straight to Put/Get
