Hi,
I've change this line with "!=" and it work. but i dont undestand why....?


void incomingMessage(const MyMessage &message) {
    if (message.type!=V_TEXT) {                         // Text messages only

Hi AWI,
Yes my display is working, i can see the date and "Line 1 - First....."

I think what i send is not correct....0_o
This is from the serial monitor

read: 0-20-49 s=9,c=1,t=16,pt=0,l=4,sg=0:test

Should it be something like this

read: 0-20-49 s=9,c=1,t=16,pt=0,l=4,sg=0:Line1=test

this is the sketch.

Hi,
i try to send message but nothing change on LcdDisplay.

I d'ont undestant what is wrong.

Can you help me pls.
