Hi All,
I have build a rf tx/rx circuit with cheap 433Mhz rf tx/rx modules available in the market and I get a strange issue with the receiver when it receives a rf signal. When I pressed a button on the transmitter I can see the LED on the VT (Valid Transmission) goes high and after about second later it goes high again even without pressing any buttons on the transmitter.
In order to prevent this I have introduced a delay in my uC about few seconds and I still want to find out what is going on.
Receiver has PT2272 M4 Decoder IC and the output from that IC is fed in to a PIC16F84A uC. Any thoughts on this.
Thanks.
