Raspberry Pi Pico: nRF24L01 over SPI 

Not only a great tutorial but provided background information in a clear concise manner. THANK YOU!

This is exactly what I was looking for. Your series on ESP01 helped me a lot, and now this is what I needed to port some projects from STM32 to RPI Pico... keep up the good work. I'm sure this channel will grow a lot. I'll suggest a second part of this one adding the MESH network capabilities of the NRF24L01.

What a shame that you don't seem to have added to this channel for a couple of years. Your tutorials are wonderfully clear, well-presented, and helpful.

Just subbed, such a wonderful work through. Keep them coming

Detailed presentation for good understanding, good.

Thanks! Great example, I’d be happy to see more data transmission, receiving and parsing tutorials.

man, exactly what i wanted. i thought i'm gonna search for days. but OH NO it only took 5 min finding this. thank you soooooo much

I spend most of my today's time learning from your videos; You have a talent when it comes to teaching, you're natural. Can you create another pico tutorial with GSM module, preferably SIM800L , to post sensor reading to a cloud database like mongodb or any nosql db. thanks and stay blessed my brother

Thank you for an nice video! I wish a merry Christmas. Best regards from Germany.

Your content is getting so good. Nice job

Thank you for another excellent video!! Definitely a weekly highlight and I’m sure my local electronics store is also grateful for your content 😄. May you please include a LoRa module at some stage?

Helpful videos, I love this board. I've never before ventured into microcontroller land I'm usually dealing with FPGAs and very low level mixed signal/power stuff. But this thing is so easy to use I dont have to bug a software person anymore to get prototypes working :)

perfect for a project I have in mind - you must have been reading my mind LOL!

Great video and beautiful explanation. Thanks regards Chris

Good content, well presented. Thank you.

absolutely fantastic tutorial! thank you!

Interesting and well presented thanks

Excellent video, very clear :)

Very nicely explained thank you

Thank you. very helpful.

Keep it up mate ❤

Very nice video, clear, concise and informative! Thank you so much. Is it possible to do this with circuitpython as well?

Hi! Really informative video! Would love to do a project implementing these, but is there a driver for just a regular raspberry pi 4? And what differences to your code would I need to make?

On many Arduino/nRF24L01 projects on the web, they state that reliability can be improved by adding a 10uF capacitor as close as possible to the nRF24L01 power pins. Inexpensive adaptor modules are available that have a 3.3V regulator and filter capacitors.

I've been looking for a Video just like this I'm still in the middle of it but I looked up info to do this project last week

oh man you saved us ❤️😀

Excellent video! do you know where we can find documentation of the other pipe line addresses? I looked in the nrf24l01 datasheet but didn't find it there.

I finally understand the SPI and i2c pin uses! Nice video. I have a question on utilization of thr feature with a developed program called lightshowpi, but even if you don't know what that is my question for now is simple enough. Can you operate csp1's gpio's in dependant of csp2's pins, both from csc's request? 2 seperate wireless gpio additions rather then extensions. The reason I ask is I'm trying to get away from 10 cords spidering everywhere from my pi4, and with a wireless receiver I hope to use minimum 2 gpio out pins for light channels. Have 6 receivers with 2 seperately controlled lights and minimum 8 controlled channels, so some receivers would be acknowledging the same command some of the time.

sir how can ı control 433 Mhz tranceiver and receiver with two pico one connect push button and the other connect led there are no library (virtulwire) for pico

When using these modules, add an electrolytic cap across the power and ground pins, right on the RF module board. Otherwise, you'll have all kinds of weird problems trying to communicate, especially with longer packets.

You are excellent

I really like your presentation style... relaxed and clear - just perfect. But I do wish your content was a bit more "hardcore" (less Python, more Assembly. More chips and discretes, less modules) but I also suspect that that would be kinda pants for audience development.... so ignore me and keep up The Great Work.

Great video. I set it up on one pico, and all seems fine. However I am trying to set up a pi 4 as the receiver, and I can't seem to find a compatible library. I am novice, but I can't seem to get any of the existing libraries to work. I would love to see you connect a pico to a pi 4.

Maybe few for now, but sir you have a subscriber from India 🇮🇳 too, 👍.

OMG YOU DID IT :D!! Hahaha thank you

great project the driver can be use for nfr24l01+?

so wait: I can attach on one Pico or Pi4 1 nrf module that will be the controller, and then on 6 other Picos 1 module and 1 Raspberry can talk to and listen to 6 others, right? or in fact each of them can talk to each other even (ok, then it will be messy to handle it). To make it every power efficient, every client is only listening, once the command comes from the controller, the client does his job (i.e. get temperature, etc. from sensors connected to it) and sends back to the controller. Then it goes to sleep (RX) again. Did I get it correctly? Btw, what would be the advantage/disadvantage between nrf vs wifi connected client (i.e. ESP)?

Hi! I'm trying to send and messages between a Pi Pico and an Arduino Uno but I haven´t figured out how to do it. Do u know a way to make it possible?

If i want create a multiCeiver is required increase the pipe´s list? or instance a new nrf object and with "for loop" start to listen each pipe one by one? thanks.

Can u try communicating esp32 and pico with nrf24l01? I'm not able to do it

For an immense improvement in performance with the nRF24L01 set the PICO SPI baud rate to 48000 in nrf24l01.py ie change - self.init_spi(48000) ( it was 4000000 )

im trying to make a small car and im trying to use this pico and nrf module......how do i do that?

Is is possible to get a troubleshoot on why it doesn't work when some of us try? Possible causes etc... Because i've seen a bunch of people including myself tried the very same things you showed and the LEDs don't light up on the other Pico.

Can you please help to how we can control BLDC with rpi Pico

Hello, I followed your instrcution but for some reason I can see the transmitter the led is blinking, but from the other pi pico does not read anything

Excelent video, tanks. Can you show how to use IRQ pin at nRF24L01?

Could you made video on nrf24l01 as a ble mode with Raspberry pi pico

is it possible to expand or increase raspberry pi pico GPIO

Hi Tim, wrt the AUTO-ack you smartly introduced: the code is activated with writing "0b11111000" to the EN_AA register (reg #1): nrf.reg_write(0x01, 0b11111000) # enable auto-ack on all pipes. The datasheet however says: "bits 6+7 are to be zero ONLY (section 9.1 Register Mapping) and use bits 0,..5" to activate auto-ack for any of the pipes 0..5. Am I missing something here ?

Does anyone know why I am getting a Hardware not responding error for the board. I have followed the instructions in the video but it never seems to work

Is It Possible To Use Tensorflow?.

Great video!!, the link for the module drivers on github doesn't work, can you please enable them again? 😇

OSError: nRF24L01+ Hardware not responding pease help

Hey can you please do a video on using ads1115 ADC converter on pi Pico ,

Fantastic series you are making regarding the PICO. I will be watching every one you make. Really clear instruction and your voice over is just perfect !!! Keep making more such videos !!! I have a few questions if I may. I have completely replicated your set up so that I can get started using nRF24L01. However, so far I can not get it to work Both Pico main.py scripts are running and I have ensured that the pipes are switched in the second Pico to ensure the TX RX side of things When I press the button, only the light on that Pico lights up and I get the print that shows tx1 and tx9 when you press and release the button. On the receiving Pico, nothing appears to be received as the rx 1 rx0 does not show. I get teh same when I press the button on the other Pico. I have checked the wiring of the nRF24L01 at least four times on both Picos to be really sure I have it right I have replaced both nRF24L01 module with new ones to make sure I do not have a bad module The except OSerror: is never fired off as I do not see a print for "message Lost" The only possible difference that I can think of so far that could be is that the version of the nRF24L01 driver might possibly be different to yours ?? Would you have any other suggestions to make to help me trouble shoot this issue and resolve it please ?? Many thanks

Great Video! Could you do one with two pi 4b's? I'm having trouble getting mine to work...

I have a problem. The receiver is extremely slow and unreliable, it seems like all messages are getting lost. The transmitter and receiver are only about half a meter apart.

Could you please show what you mean with: the only difference in the software if the two picos is: ? I did not get the point about how to change the pipes.

Is it possible to adress more than six devices? Like giving 10 devices the same adress and using an additional device id in the payload?

Hi, does this library work on esp8266 or esp32?

Heĺlo , I need some help i can get the data transmit and receive successfuly but the problem i get is 10-20time i send and i receive 1 time can you fix this lag delay? thank you in advance

Im confused, got scripts working on both my nrf modules, they can both send and receive. But when I press a button only the pico connected to the button led turns on. The other doesnt get the message and led doesnt turn on.

Something very odd going on with your demo code, or my understanding of how these work. When the button changes state, it transmits the state, presumably on the tx_pipe. Then it returns to listening, presumably on the rx_pipe. The receiver receives the data without listening on the transmit pipe, where the data 'should' be being transmitted. Also, changing the pipes[0] and pipes[1] to exactly the same address has no effect on your code. It behaves the same.

The github link is broken, is there an updated link anywhere?

It doenst work can someone please help me? I did every thing like in the video but it wont work I need Help please.

Also Could You Do A LoRa Tutorial With The PICO?.

Can you please make a video for transmitting data pi Pico to Arduino Uno via nrf24l01 🙏🙏🙏

does your code mean to say that 1 Pico should have pipes = (b"\xe1\xf0\xf0\xf0\xf0", b"\xd2\xf0\xf0\xf0\xf0") and the other has pipes = (b"\xd2\xf0\xf0\xf0\xf0", b"\xe1\xf0\xf0\xf0\xf0") ...because the communication isn't working for me yet

Bro can we use nrf24l01 as wifi module, i mean can we connect it to cloud

please sir nrf24l01 & raspberry pi pico based 7 channel transmitter & reciver making vedio next please ?

your voice recording peaks at -20db, please bring it up to -9db

I love how with such even voice you can keep rattling off all the part names and acronyms. I would resort to saying the wireless thingy after one or two attempts.

Oh stop it Master Slave is completely appropriate name for electric circuits.

4:14 Oh for fuck's sake. I'm out.

computerlivesmatter ffs

PC meets electrical engineering :-(

Don't need any woke renaming BS.

If the terms master and slave offend you then you should find another hobby.
