How to do resend when st=fail on a Repeater

[doblanch]

everything is in the title :-)
I'm wondering how to increase reliability on bad RF transmission (big ceiling).
I want to do a resend when st=fail.
I do it already on my sensor, it's easy to code, as it's in the sketch directly.
I'm wondering how to do it in the repetear ??? some ideas ???

@doblanch ,

I see two ways of implementing it (despite I never tried):

1. gw.send( msg ) returns false in case transmission fails.

OR

2. gw.send( msg, true ) will request an ack from controller, which should arrive back in few seconds if everything went well.

In both cases, you have to write your own logic to retry.

@rvendrame Hello,
yes, I use this already. But as you know in a repeater, the gw.send is not available as it's include in the process() function... I do nont have access to gw.send...

@doblanch , not sure if I understood. gw.process is used to listen to incoming radio messages, while gw.send is to transmit messages, and is present on every example sketch here. For example the 'Door/Window/Button' sensor:

void loop() 
{
  debouncer.update();
  // Get the update value
  int value = debouncer.read();
 
  if (value != oldValue) {
     // Send in the new value
     gw.send(msg.set(value==HIGH ? 1 : 0));
     oldValue = value;
  }
}
