Hello guys. I know this is off topic but i am stuck with RF Communication.
I have an arduino which i want to use as RF receiver and a Raspberry Pi 2 which will act as RF transmitter. The problem is that I just want to replace the USB cable from RPI to arduino with a 433 MHz Tx-Rx pair. I want to do it as USB Serial as i only need to transmit low volumes of data. I also have a USB to Serial converter which I think I may need.In short, i just want to make the process wireless with RF Communication. Please help me out.
EDIT
I dont want to program the arduino over RF or anything but just send data from a running python node like this :
RPI(ROS Python Node) ---> USB to Serial Converter ---> RF Transmitter ---> Air ---> RF Receiver ---> Arduino
This sounds like an electronics question. You may have better luck on the electronics stackexchange forum, or another electronics forum.
This is not a bidirectional connection, so rosserial is out. You have to write your own python node, that sends the commands you want to your base. This has nothing to do with ros.
