RF 433 MHz communication between Arduino UNO/Feather32u4 and RPi

Projects Networking, Protocols, and Devices

Hello!

Me and my friend are doing our thesis-project in university and the last step is to communicate from a Raspberry Pi to the Arduino(we have the UNO and Feather 32u4 available), wirelessly. We have tried bluetooth with no luck and are now trying RF instead. We only need to send minimal data (ex. a number) and are wondering if anyone here have done any similar projects and maybe how we can proceed further? We have tried example-code of RadioHead and piVirtualWire but have not given any result and we are using the most commonly used cheap transmitter and reciever.

UPDATE: rpi-rf is now working on the Raspberry Pi where both transmission and receiving is done on the Pi, now we need to somehow receive it on the Arduino instead. The fix was to screw on the thing on the receiver.

Thanks in advance!

which Feather 32u4 are you using - is it the 32u4 Bluefruit LE ?
if your a looking at BLE try a web search for raspberry pi ble arduino

Hello horace, sorry for the late answer! Yes we have the Bluefruit LE. We have at the moment ditched the arduino and is instead using two RPi's with RF-communication instead, the communication works but is not as reliable as we thought because sometimes it works and sometimes not. We have also tried soldering antennas to the transmitter and receiver but unfortunately this do not help that much.

how far apart are the devices? what protocol are you using over WiFi? TCP, UDP, ?
