- Updated OBEX to support SRM - Added support for OBEX over l2cap and SRM. - Minor bugfixes, and reduce CPU load ALOT - Added support to send responses without body data. - Extend BluetoothSocket to support L2CAP - Added functionality to get the channel number needed to be able to create an SDP record with the channel number. - Added interface to get socket type and max packet sizes. - Added interface to perform SDP search and get the resulting SDP record data.
