void receive not work with RelayActuator.ino ?

[yourry]

Hi all,
I don't understand a problem,
My receive function is not working in the sktech relayActuator.ino
If I simply add the following code :

....
void receive(const MyMessage &message)
{
   Serial.print("--- Incoming Message ---");
  // We only expect one type of message from controller. But we better check anyway.
  if (message.getType()==V_STATUS) {
....

I never have anything.
But in the node logs I do receive the information:
Relay OFF :

345110 TSF:MSG:READ,0-180-162,s=180,c=3,t=6,pt=0,l=1,sg=0:0

Relay ON:

355655 TSF:MSG:READ,0-180-162,s=180,c=3,t=6,pt=0,l=1,sg=0:1

For information I use a gateway+W5100 in MQTT.

An idea why the receive function is not working here ?

Thank you all

@yourry Don't use serial print inside the receive function.

instead set a variable in receive and test for that in the main loop and then send serial from the main loop.

This is probably all the problem is........ probably....... ;)

Thanks for the answer, I keep the advice.
Finally I looked for a while and the problem was with the MQTT publish syntax.
It works perfectly, the difficulty is to find the right publish MQTT request.
Thank you.

@skywatch said in void receive not work with RelayActuator.ino ?:

Don't use serial print inside the receive function

Why not? Receive doesn't run in interrupt context, so it should be safe to serial print from it...

@Yveaux I'm sure it's in the forum posts somewhere but I don't have time to look for it.

Maybe you could do a list of what is and isn't possible in void receive to mitigate further confusions?
