Rpi-rf 433mhz receiver transmitter

Hello guys, have you ever tried to communicate with the 433mhz receiver and transmitter via raspberrypi 4? It seems that the receiver is not receiving the signals. I tried the same application with Arduino and it actually worked. Any ideas why I can't receive the signals? I use python3 rpi-rf package for this. The wiring between the pi and the transceiver is fine, I doubled check it.

Have you added a correct antenna?

And please crop the picture

Hi, thank you for your reply. The antenna is not really necessary, especially when the transmitted signal is so high. As I mentioned before, the receiver could receive the signals when I used Arduino. As for the image, somehow I can't edit the image in the message, I'll try later when I'm home.

No antenna and you lower the Vcc from 5V to 3,3V, just thinking out loud.

The VCC that comes from the Pi is 5V isn't?

or 3,3v. If you supply it with 5v you need level converters on the GPIO pins

Really? Didn't know anything about that. Currently I supply it with a mobile charger, I guess it can supply more than 5v since It supports 65w. Anyways I'm not sure the Pi has a PD controller so how should I supply it with higher voltage and type c connector?

I guess you meant the IO's that send and receive data. I Actually don't know what the levels of the data between the receiver and the Pi, can you confirm it's not 3.3v?

Check the datasheet

Same module for 433MHz

So I checked both 5V and 3.3V as VCC, Still doesn't work, the receiver doesn't send anything to the PI

Does anyone know what the problem is? I'm not sure this is about the logic levels between the modules since it's working on Pi 1/2 without logic levels converter
