I try to send a byte[] () over a established SSL Connection (handshake etc is done).

The result: The byte[] is spitted into two packets (see debug below):

- First packet: just the first byte of the application data (*****01*****) .
- Second packet: the rest (fe db 01 00 ...) 650 Bytes

Is there a way to commit all application data bytes in one packet?

Stream to send 651 Bytes:

**01** fe db 01 00 00 02 83 3c 3f 78 6d 6c 20 76 65 72 73 69 6f 6e 3d 22 31 2e 30 22 20 65 6e 63 6f 64 69 6e 67 3d 22 75 73 2d 61 73 63 69 69 22 20 73 74 61 6e 64 61 6c 6f 6e 65 3d 22 6e 6f 22 3f 3e …
