Hope you can help me, please:)
I have bought this RF link kit(seeedstudio.com/depot/433mhz … th=139_140). When I want to send a message from an arduino(let’s call it “A”) to another arduino(“B”), everything is fine: the Arduino “A” send the message using the transmitter, and the Arduino “B” get it through the receiver. The problem is when I want to add the transmitter and the receiver on the same Arduino. For example, if I try to send a message by the transmitter on the Arduino “A” to the receiver always on the same Arduino, the message is sent, but it doesn’t receive it.
I use the Virtual Wire 1.9 library: open.com.au/mikem/arduino/VirtualWire.pdf
Any idea why?
Thank you so much!
