I can successfully transmit and receive between these two devices.
$ sudo ./codesend 500000 sending code $ sudo ./RFSniffer Received 500000 Received 500000 Received 500000
I also have a 12v 4 channel relay that has a built in RF receiver and came with a remote transmitter. The paper than came with this relay kit says it is operating at 315mhz.
I want to sniff the codes from the remote for this relay kit. Whenever I try to run RFSniffer (433Utils) with the remote, it doesn't pick up anything.
On the back of the XD-RF-5V receiver it says 433mhz, 330mhz, and 315mhz so I would assume it can receive 315mhz signals.
Am I doing something wrong or making incorrect assumptions? Is there something I need to do differently to receive the 315mhz signal? Can this receiver even receive both 433mhz and 315mhz signals (like it says on the back)? I am a bit new to RF (and electrical hardware in general) so I am not really sure how these different frequency devices play together.
