I expected that I don't think you can do that. A user message is mapped into a DTLS message. This is limited by the protocol (I think there is a limit in the 16 KB range) and by the MTU of the path, which is normally about 1500 bytes. Sending larger frames would require IP level fragmentation, which normally has to be avoided. >> SSL_MODE_ENABLE_PARTIAL_WRITE would work in a way that SSL_write() >> returns a value suitable for a UDP datagram so I send it and then call >> SS_write() again by passing the following chuck in my data buffer. >> >> Is it a bug? or am I missing something? Not sure... I think allowing this in the API doesn't make much sense.
