Raspberry Pi Tutorial 35 - Wireless Pi to Arduino Communication with NRF24L01+ Part 2

How to establish two way communication between a Raspberry Pi and an Arduino using a NRF24L01+ transceiver. These are inexpensive transceivers allowing for high speed long range communication sending upwards of 2 Mbps. This is a master / slave setup between the Raspberry Pi and Arduino, following up on a previous setup tutorial.

Clearest and most efficient tutorials anywhere on micros. Outstanding.

You sir are a hero. I've been dreading taking on communication between the pi and a arduino for months and you just helped me do it in a day. Thank you! Subscribed.

[peterryder]

Worked great for me. Thanks very much for taking the time to do this tutorial. No way I would have done that myself.

[MauroPolgatti]

Really great work.
I spent days following other tutorial with no
In no time following your video I have the communication between my arduinos and Rpi 2.
THANK'S

[akovbych]

Thank you for your tutorials! Everything works fine, everything is clear!
It will be very interesting to see tutorial how send information from sensors, that connected to Arduino (like current sensor or temperature) to Raspberry and handle this information - build graphs with depending on the time and so on. Can You create tutorial about this?

increible, amazing, perfect VIDEO, bless you

[brightmurima]

thank you for the tutorial, i tried tutorial 34 and it worked out perfectly but now with tutorial 35 my arduino is not receiving from my pi. i am using raspberry pi 4b. Any Solution?

let's make it modern and futuristic GETSTRING: "HELLO UNIVERSE"..😄..thanks for the tutorial...with salute

[jasperdegraaf]

First of all, thank you for these very clear tutorials!
I have a question regarding the NRF24L01+ transceiver modules. Do I have to worry that these modules may interfere with a 2.4GHz WiFi signal? Since my local area is already quite crowded with 2.4GHz WiFi signals and I don't want to cause any trouble with either the WiFi signals, or the signals of the transceivers.
Thank you very much!

thanks for the great video! But I'm having some trouble. I am attempting to send a message to the arduino from the Raspberry pi. The message changed based on a switch. Everything is working properly except for the fast that either A)the Raspberry Pi is only sending the first character of the list, or B) the arduino is receiving it wrong. for example "hello world" is sent, I only receive "h" 32 times. I am out of ideas on what could be wrong.

Thank You for giving the amazing Video. I have followed the video but i am unable to send data from Raspberry Pi 2 Model B. It all worked fine to receive data from arduino to RPi but radio.write() function does not work while sending data from RPi. i get the following error


Runtime Error:Please set pin numbering mode using GPIO.setmode(GPIO.BCM) or GPIO.setmode(GPIO.BOARD)

i had set the mode to GPIO.BCM in my python program

[srikrishnajujjavarapu]

your imported package is showing some warnings regarding some redefinitions of some constants. Is it fine ?

[raffotirator]

thanks for tutorial, but happen a strange think: i can communicate from arduino to raspberry, but when i send a message from rasp to arduino it don't works!

[inhibited]

if you have two temperatures to send instead of hello world, is there a way to figure out a second pipe address, or do you just open and close the pipe to send data? I am getting data from level indicators x, y, z, so I might need multiple pipes

[hamoodelholandy]

Great video __
but im asking how to send Array of integer from Raspberry pi to the Arduino

[ahdhs]

hello, please can you work on the same vedio but by using DHT22 sensor

[sanjays]

i tried hard with the tutorial ...i dont get any error but the two boards are no communicating....meanwhile im not even getting error too....i hav also used 10uf capacitor still the condition is same

[icrodriguez]

thank u so much papu! it worked excellent

[TheVermasachin]

Hello, first of all, thanks for putting these nice videos, they are really good.

So I was successful in running the ONE way communication code. However in this tutorial, its seems raspberry pi is getting timedout on every message. Therefore not rcvg any message in my Arduino. Any advice as what I should check to fix the timedout issues?? I am very new to Arduino and raspberry pi so not able to troubleshoot.

Appreciate your help.

Also do you have the codes for these examples on github or elsewhere? just want to make sure that I dont have any typo in my code

[boherrmannsen]

how would it look if going the other way? from the pi to the arduino?
