Felix: Is this possible?

James: Yes, it is. It is disabled by default because it can generate quite some traffic. But it can be enable from a SC plugin just fine. See IR Blaster plugin - switchIRRepeaterStatus().

First a plugin needs to register a callback function to receive RAWI data then it needs to tell the player to actually send them. That is achieved by sending a 'ilrn' command with one parameter about how many packets one would like to receive (max. 255).

sub switchIRRepeaterStatus {
  my $class = shift;
  my $client = shift;
  my $status = shift;
	
  if( $status eq "on") {
    # Check if function is available
    if( UNIVERSAL::can( "Slim::Networking::Slimproto","setCallbackRAWI")) {
      Slim::Networking::Slimproto::setCallbackRAWI( \&RAWICallbackIRRepeat);
    }
  }
  if( $status eq "off") {
    # Check if function is available
    if( UNIVERSAL::can( "Slim::Networking::Slimproto","clearCallbackRAWI")) {
      Slim::Networking::Slimproto::clearCallbackRAWI( \&RAWICallbackIRRepeat);
    }
  }
  if( ( $status eq "on") || ( $status eq "more")) {
    # Ask SB2/SB3 or Transporter to send 10 ir codes (containing x samples)
    my $num_codes = pack( 'C', 10);
    $client->sendFrame( 'ilrn', \$num_codes);
  }
}
