I want to implement the function 'Send a file' in the image enter image description here
I want to implement step 4 in the link Send files over Bluetooth in Windows
I set the guid below,
RemoteEndPoint.serviceClassId = OBEXObjectPushServiceClass_UUID;
I want to send a image to my smart phone.
So, what do i use socket send api? I konw now my send code is false.

Final,i find the solution. OBEX connect like this:
How does the OBEX protocol look like?
OBEX PUT command like this:
const char* str = "82002bc30000000f01001100620074002e007400780074000049001268656c6c6f2c20776f726c64200d0a";
/* Put | 2B len| HI len | Name| b t . t x t |HI end|h e l l o , w o r l d \r\n */
