send many variables in one messages

[Marcin]

Hi.
I have a problem with Blinds. I work with domoticz.
I try to use one STM32 to control 6 blinds. My sketch calculating position (depend of time) and provide V_UP, V_DOWN and V_STOP buttons for each blind.

But I want to send actual position to the controller when blind is moving.

At start i create Message:

MyMessage msg(0,V_COVER);

Presentation section:

for (int i=0; i <= blind_cont-1; i++){present(i, S_COVER);}

And when I want sent actual position :

for (int i=0; i <= blind_cont-1; i++)
                    {
                      if (dstatus[i] != V_STOP) {
                      send(msg.setSensor(i).setType(V_PERCENTAGE).set(dposition[i],5),false); wait(250);
                      }
                      
                    }

It;s correct ? Becouse DOMOTICZ doesn't receive anythink.
