Hye everybody!
I have a trouble...

(The sketch used is RelayActuator)

If a clear my eeprom with the sketch in the example, and if i upload a new sketch after, nothing appened. Zero message in the serial gateway and zero message in the serial of the sensor.
If i specify a NodeId, nothing else...

The solution : i clear eeprom with the original sketch of arnduino (with 0 and not 255 or 0xff) and upload a new sketch, messages are send.

If i specify a NodeId, the message is : 1;255;0;0;18;1.4
Is there a problem with my childId? why 255? and why there isn't the sketch name which appear in the serial gateway? Why is there no message when i clear EEPROM whith the "official" method?

I don't understand.

Please help me!!!!

You can't control blinds motors with an optocoupler. If you tried this connected to your blinds, you opto is dead....
Use a relay or an optotriac + triac

@ferpando
Hye!
Yes, it will work. I used a led for testing the actuator example and it works great.
What would you like to command?

ARF!!!!!!!
3 years i use Arduino and i have never pay attention to this line...
Thanks!

I haven't understand this question, we can't change this in arduino?

I have found where is the error!
In the SerialGateway sketch, if we use the serial monitor with arduino IDE (with my PC), there isn't a "\n" char who is send.
i have to change this in the sketch with z.
now it function!!

so the new serialEvent function is :

void serialEvent() {
while (Serial.available()) {
// get the new byte:
char inChar = (char)Serial.read();
// if the incoming character is a newline, set a flag
// so the main loop can do something about it:
if (inputPos<MAX_RECEIVE_LENGTH-1 && !commandComplete) {
if (inChar == 'z') {
inputString[inputPos] = 0;
commandComplete = true;
} else {
// add it to the inputString:
inputString[inputPos] = inChar;
inputPos++;
}

} else {
   // Incoming message too long. Throw away 
    inputPos = 0;
}

}
}

and to activate my led (or relay), i use this line : 42;3;1;2;0z in the serial monitor on arduino

Is it my PC, the Arduino serial monitor or the script which isn't atapted with this tools?
i don't know...

Et voila for the solution (for my problem in fact)
thanks for all!

I use arduino ide for serial communication.
I write 42;3;1;2;0 in the serial send line and clic on Send.
Nothiing appears.
For debugging, i had Serial.println(inputString); at the end of serialEvent funtion for testing what i was sending
and i have this appearing :
0;0;4;11;Arduino startup complete.

Hello!
I have inverted the 2 arduinos, now nano is the relay actuator node and the mini is the serial gateway.
Nothing happens else...
Someone can help me?
thanks

I've tested with an another computer near the first (1 meter)
the only things i see in this serial monitor (the relay or led node) i have this :

Started sensor.
Relay=0, distance=1
Relaying message back to gateway.
Tx: fr=42,to=0,la=42,ne=0,ci=255,mt=0,ty=17,cr=166: 1.3b3 (18848a2)

nothing when the gateway send this : 42;3;1;2;0
I have inverted the two nrf24l01 and it is the same
Any idea?

OK for the serial Gateway.
My radios communicate really. I test it with a ds18b20 and i have my temperature (thanks for yesterday!!!)
I've just activate the debug and it says :

I don't see anything when i send this : 42;3;1;2;0
I think my numbers are good
I don't understand why it doesn't work
