I use scandium with leshan and tinyDTLS for luadtls and lualwm2m.
I confirm, I see what you describe using wireshark and it seems scandium wait for the flight 5.
At least, it works for me.
Did you found any problem ?

Finally I connect between tinydtls and scandium, but as I wrote I think Scandium is waiting for flight 5 and after each one small record (not whole records in one message) it sends message from flight 4. This two messages (~570B messages) are handling without effect by tinydtls, but it consume device power and slow down handshake.

Hi @kl-cruz ,
is this still an issue? The way I read the Scandium code, it does not require a client to send all messages of a flight in one Datagram. However, Scandium will re-transmit the previous flight (by default the initial timeout is 1 sec which is then exponentially increased) until it receives the FINISHED message.
