When trying to send an array of 1000 float through a Jamoma return, I got this message in console on client side :

TTOscSocketListener : "element size must be multiple of four"

It runs on a Raspberry Pi,
the sender code is here : https://github.com/avilleret/gorgone/blob/0faa634304e24d681ac805a55861b5b9a4d53a03/src/gorgone.cpp#L114-L125

and the receiver is a Puredata patch : https://github.com/avilleret/gorgone/tree/0faa634304e24d681ac805a55861b5b9a4d53a03/Pd

Both runs on the same Raspberry Pi 2 with Jessie
