no, because the L2CAP is a SOCK_SEQPACKET. You must send the packet at
once. Otherwise you will get bad fragmentation.

Look at the RTP RFC they mentioned in the specification. I didn't
checked it. Simply used the stuff I've seen in my trace.

And btw the endianess may differ between parts of the Bluetooth protocol
stack. This is the problem when you adapt other protocols.
