This is my first question here. I want to have a communication channel which will use a 433 MHz RF TX-RX pair. I want to use a Raspberry Pi 2 as a transmitter and an Arduino Mega as a receiver. Is it possible to replace the usb cable using the RF transmitter with a USB to Serial TTL Converter with the Raspberry Pi 2? The communication would be like this :
Raspberry Pi 2 --> Serial (USB) port --> USB to Serial TTL Converter --> RF Transmitter --> Air --> RF Receiver --> Arduino
Now I dont want to program the arduino wirelessly or anything but only have the Raspberry Pi send small (extremely - about 100 bytes/sec) amounts of data from a python code to the arduino wirelessly.
