NodeMCU ESP8266 repeat my send signal twice causing light to turn "ON" then "OFF" instantly.

Hello all

 mySwitch.enableTransmit(13);  //nodeMCU GPIO13 --->D7
// set protocol (default is 1, will work for most outlets)
/* mySwitch.setProtocol(1)  */
  mySwitch.setProtocol(1,304);

 // Optional set pulse length.
 //mySwitch.setPulseLength(320);

 // Optional set number of transmission repetitions.
 mySwitch.setRepeatTransmit(4);

BLYNK_WRITE(V52)
{
int pinValue = param.asInt(); // assigning incoming value from pin Vc to a variable
if (pinValue==1)
mySwitch.send("010011110001000000110000"); // DINING ROOM   B  (Medium)
Serial.println("V52:DINING ROOM   B  (Medium) ON/OFF ");
}

here is the serial print for any button i pressed.

V52:DINING ROOM B (Medium) ON/OFF V52:DINING ROOM B (Medium) ON/OFF

I tried changing transmission repetitions , pulse length but no hope. always i got the signal transmitted twice.

thanks

So you have a switch which uses the same signal for turning someting on and off? That's somwhat unusual, as most systems rely on repeating the transmission multiple times to deal with signal losses.

Anyway, you hav mySwitch.setRepeatTransmit(4); in you sample code. Did you try it with 1 instead of 4 (you said you "tried changing transmission repetitions", but it is not clear from that what exactly you tried).

When I tried 1 the 315Mhz receiver connected to my nodeMCU (ESP8266) serial print reported that two repeated signal was sent but unfortunately no response from the hardware. same with 2. with 3 it works but few times i got no response from the hardware. the best choice was with 4 but still light goes on then off (with that type of HW switch ) in all 4 serial print reported that two repeated signal was sent.

here i must mention that when i use the original remote i got one signal sent with serial print.

thanks
