Superheterodyne receiver ( WL101-341) problem

[dajak]

I recently bought 433 MHz Superheterodyne receiver ( WL101-341) and I'm having problem receving signal from my 433 MHz remote. When I test my script everything is fine if the Serial monitor in Arduino enviroment is on. If i close the serial monitor, the 433 MHz Superheterodyne receiver stops receving signal. So the problem is related to this specific reciver model which requires Serial monitor to be opened for the rc-switch library to function correctly. If i replace 433 MHz Superheterodyne receiver ( WL101-341) with cheap XY-MK-5v receiver the script and rc-switch library runs correctly regarding the status of Serial monitor. Has anyone had similar issue with this 433 MHz Superheterodyne receiver ( WL101-341) ? Yes and I'm using reciver with esp 8266 e12 node-mcu board.
