Send time request over arduino "monitor serial"

[hek]

yes, you can

[ch3b7]

how, who need send?? or an example

[hek]

Something like:

<node-id>;255;3;0;1;<seconds since 1970>\n

[ch3b7]

thanks, the problem is i dont know who is "<seconds since 1970> any example? im use a custom controller.

[hek]

Depends on your programming language. Normally you would have a function returning milliseconds since 1970. Just divide this with 1000.

WORK! im get "1420578901" ^^ thanks HEK!

im have other question about the light actuator with a button, i send the command to tun on/off its works, but can the node can send again the new state when received the turn on/off command? sorry for my bad english im from argentina^^ im needed to update the state in my controller and know if the command sended work.

this work but when i press the button the controller send 2 sets commands

**void incomingMessage(const MyMessage &message) {
// We only expect one type of message from controller. But we better check anyway.
if (message.isAck()) {
Serial.println("This is an ack from gateway");
}
if (message.type == V_LIGHT) {
// Change relay state
state = message.getBool();
digitalWrite(RELAY_PIN, state?RELAY_ON:RELAY_OFF);
// Store state in eeprom
gw.saveState(CHILD_ID, state);
// Write some debug info
Serial.print("Incoming change for sensor:");
Serial.print(message.sensor);
Serial.print(", New status: ");
Serial.println(message.getBool());
gw.send(msg.set(state), false); // Send new state and request ack back
} **

Just request ack from the node by setting ack parameter to 1.

<node-id>;<child-sensor-id>;<message-type>;<ack>;<sub-type>;<payload>\n

The node will then respond back with the same message in return. (You don't need to update sketch code)
