thanks you, very easy to understand, it cant be more simple and clear , i"ve been trying to understand how to code the mesh network, now it is easy and clear, Thank you for this tutorial......
Thank you! Concise and full of information! According to diagram @3:00 minutes the hierarchy works in that way that the message for the lower nodes can go up/down a straight way from/to base node. When message needs to go to other node in the same hierarchy level or on the other level it must first go straight way up to base node than down to the destination node. But, if we look on the diagram @6:11 minutes it looks that that hierarchy is not respected. How? 1. Base 00 (blue line) to Node 012: first send message to Node 02 than Node 02 will send to Node 012. The line must go through the rectangle of Node 02, not away of it. 2. Base 00 (pink line) to Node 022: first send message to Node 02 than Node 02 will send to Node 022.The line must go through the rectangle of Node 02, not away of it. 3. Node 012 (green line) to Node 01: first send message to Node 02, Node 02 to Base 00 and Base 00 will send message to Node 01. The line must go through the rectangle of Node 02 than to Base 00 than to Node 01, not away of it. All of that to avoid confusion.
This is so awesome! I'm planning to do Spider Cam system to my biggish workshop. One arduino is the "controller" and then on each corner (four of course) of the workshop there's stepper motors to control the single wire. ChatGPT implemented some code for me already for this! 😀
Maybe i missed it in video, but... These modules are great for almost 100m distance, in open area and 2m above ground. Every single tree will drop range significaly. In a house project two of these modules separate by two walls can hardly achieve 8-10m range. If there are bunch of wires in walls behind one of them, range will drop more, and loss of packets will increase. Better solution would be use of PA-LNA versions. Or, to use third one for a bridge between two of them in a node manner as Dejan pointed in video. Beside, local network can mess up things even more. So, channel must be set 108 or above. 115 is pretty much ok. Data rate to 250. The other thing to notice is, these modules has Gremlins. Dupont cables can be used for making a project. For a finish product, dupont cables are out of business. Only hard-wired and capacitor on power lines is a MUST. Or to use an adapter for them, which is pretty good. Good one, btw, Dejan. Cheers.
Hello tnx for the GREAT tutorial. Can I connect a nodemcu to an Arduino which is wired to an NRF module? If yes , can I use the same libraries you used ?
I don't even have and Adruino (yet) and I understood everything. The potential here is ENDLESS !!! One new SUB here. What is the distance of the NRF24L01 module ?
Thanks! The NRF24L01 module distance in open space should be up to 100 meters, and if the model is with the big antennas it should be up to 700 meter. But that would be significantly less if there are obstacles.
@@HowToMechatronics Thanks for your response. Very kind of you. I am looking at a project that will have obstructions in it maximum 150 feet... Wires concrete... etc etc. I would need to find the strongest module of this type out there.
Your videos are really..... Cool..... Can you create...... A full playlist of....... Using NRF24L01 from..... Beginning to.... End...... Complete tutorial........
Wi-Fi uses -master - slave- oops, I mean primary-secondary connections (it's 2020 lol) while Bluetooth is peer-to-peer you can connect a bunch of wifi clients to a hotspot but then that hotspot will not be able to connect to another hotspot ... you would need 2 wi-fi modules on a single device for that, which is really innefficient. wi-fi wasn't designed for this. wi-fi modules are for many-to-one connections where a device can be wither a client or a host but now both, and the networn is encrypted, secured and high-bandwidth ... basically for internet tethering ... that's what wi-fi was designed to do connecting a whole bunch of devices through wi-fi, even if some of them had multiple modules so you could link them together would still be a huge pain in the ass because you would soon get horrible interference because there's only so many possible wi-fi channels so if you want to make a wi-fi network ... just go ahead and get a powerful enough router and connect everything in a single network instead
hello an excellent project, I have a question how you define the, 0 and 10 for each specific node and if I wanted to use another node how can I define that data is the code of node 01 if (header.from_node == 0) if (header.from_node == 10) Thank you
Hi! Thank you for this tutorial. You have laid this out so well. One thing I am confused about is at 7:30, where you explain "header.from_node", I couldn't see how some of these values correspond to the node numbers. First you say, if (header.from_node == 0) { // If data comes from Node00. This DOES makes sense. But then you say, if (header.from_node == 10) { // If data comes from Node012. This is what confuses me. How does 10 mean Node012? Am I missing something here?
Great video. I assume the same can be done with a mix of Arduinos and Raspberry Pi’s at different notes? I am trying to mix Arduinos and Pi’s on the same network.
Thankyou sir, Can this method still be used when using up to 5 NRF24 in both directions(receive and transmit all of NRF24) together sir? Will the response time be long?
Wow, thanks a lot for sharing such a perfect talented tutorial. Can it be applied for ESP32? If not, can't wait to see that u may come out with ESP32 mesh tutorial. 😊
Hi, a very good Tutorial! And it works fine! But i have a question... Which variable i have to change in the code, to create another Mesh-Network? I need a second one in the near of the other.
I have a idea. In code(next to node address), he wrote octal format. Convert 012 to 10. (8^0)x2+(8^1)x1+(8'^2)x0=10 (if you dont understand , google octal format.)
You really know how to explain. Great, please continue. I have a question: Which programmer do you recommend for programming the Arduino Nano? Please supply a link. Thanks in advance.
thank you sir for this excellent video, but its not working when i checked for Node 00 and Node 012 and when i does not connected other nodes (when i want to on or off led of NODE 012 controlled by Node 00) please help me sir
Can we connect node 01 directly to node 02, so that every successful step in the tree the nodes are connected to each other to reduce traffic through the central node?
Good morning...a question...I made up wire harnesses with CE to pin 8 and CSN to pin 10 for another project tutorial. I notice you have CE to pin 10 and CSN to pin 9... Would these work if I changed Node 00 code on line 13 to "RF24 radio(8, 10);" and Node 01 code on line 10 to "RF24 radio(8, 10);" ...just wondering if any of your included libraries reference this? Thanks for making this tutorial...look forward to your reply.
Loved the video but I want to make 4 door sensors and one receiver with led indicators on the receiver so is it posable to change your sketch to do this thanks Bob
Excellent video I have been looking for something like this for a long time. A couple of thoughts first thing can you use an ESP8266 for all nodes if you can which library’s would you use, second if you use an ESP8266 you can do away with the Arduino boards.
thank you a lot, so it has to be 5 level deep network? my network has to be vertically long, not horizontally, because i need a long range coverage, is there a way around this?
Hi. Appreciate your videos. Did you explain the 10microfarrad capacitor? I see it in the schematic, but didn't hear anything about it in this video, or your previous videos. Maybe I missed it, but a refresher would be great.
Thank you! Well I mention the capacitor in the first NRF24L01 Tutorial. It it used as bypass capacitor, or to stabilize the power supply to the module, because when starting transmitting data the module could draw a bit more current, so in such a case the capacitor will help the circuit maintain stable power supply.
Can we use multiple nodes with same address in a network? Actually, my requirement is to send same data to all (up to 20) clients a time and all clients has to send data to master individually.
Can this work over two different networks? So if I have an Arduino board in my house and one in my neighbors house can they still communicate to each other?
Is there a reason you used long instead of int data types? Wouldn't it be more efficient to use an unsigned int and byte for 0 ~1023 and 0 ~180 respectively?
Hello and congratulations for your videos. I'm a newbie. I need to receive information from two sensors on two different cards: I can't diversify the two packages on the receiving card and the result is that I receive only one. How can I do?
Any chance to have a UA-cam video using the SAMD processor instead of the AVR? Currently, the RF24Network doesn't work with any of the faster SAMD boards which are nice to use when using TFT displays for all the nodes in the network.
Sir i want to make address of five digit Integer number like- this_Node = 31211 : Node1= 31222 : So, What i have to do sir or what are the changes i have to do,
I prefer to use Pcbway because they can check my design files mantually and help fix the small design error. So PCB always works perfectly and Fab quality is flawless. Moreover, there is no difference for me between $5 and $2.
Thank you! That's a good suggestion but currently I have quite a big do-to list with other projects and tutorials, so it would take me some time to get to this one. Cheers!
Hi I have Arduino Uno with 3 pins connected to Max7219 with 7-segmentLED. How is it possible to send data to another 4 Arduino Uno using NRF24L01 so I will have exactly the same displays on all my 7-segment LEDs. Thank you
hi sir i have a problem with module nrf24 with using multiples noeuds and one of this noeud play the rules of router sending and receving data can you help mee please
My goodness I've tried so many times and couldn't find a good tutorial to do this. Thanks a lot for making this video!
Justin Straver!
you have no idea how much this helped me, i had almost given up on trying to figure this out
I'm glad to hear that!
I have four modules on the way and I can't wait to do this project :-) thank you for sharing your talent with us.
Best NRF24L01 Network tutorial so far! Thanks for sharing!
Thank you for very clear explanation on how to create network of multiple NRF2401's Learned alot!
You made it pretty simple! I was very confused from this library till now. CONGRATS!
Thanks, I'm glad to hear that!
Wow! I've been waiting for something like this. Thank you!

All of that to avoid confusion.
pretty sure it was just explaining where data goes not HOW it gets there

I gave a "like" and I suscribed. Thank you very much for this amazing tutorial. It is so helpful.
Thank you. this video is the best! Wish you all the luck in your life !!!!!
Excellent tutorial! Very well explained. Thank you
Thanks!
this is excellent im going to make something not sure what but definitely something using your tutorial.
u are really great boss. ur every tutorial is real and good . i follow ur project also try those and be success.
I've referred to this several times, and your code. Thanks so much, bro!

never success communication while using NRF on bredboard, may b the loose connection or something else, but working perfectly on PCB
That's great project description Sir......
sir I faced issue while storing the different sensor data at receiver side . In which the value get shuffled between two variables .
Great job on explaining. Thank you.
Thanks!
Your videos are really..... Cool.....
Can you create...... A full playlist of....... Using NRF24L01 from..... Beginning to.... End...... Complete tutorial........
Great video! - if I wanted to make two systems with this setup so having in total 6 arduinos. Would the systems interfere with each others?
i had the same thought, anyone with an answer pls
Use different channels
at nRF24L01 Network No any protocol follow as nrf24L01.h pipe following
DUUDE! awesome video and awesome example. We need more awesome dudes like you.
Excellent video...can u teach us to build the same network using LORA instead of NRL24
Sir can u make use of Wi-Fi module(esp8266) instead of Bluetooth

is the code of node 01
if (header.from_node == 0)

Hi, a very good Tutorial!
And it works fine! But i have a question...
Which variable i have to change in the code, to create another Mesh-Network? I need a second one in the near of the other.
Node 01 is receiving from node 00 & 012
Then why have u used 0 & 10 to check received data , please reply
I have a idea. In code(next to node address), he wrote octal format. Convert 012 to 10. (8^0)x2+(8^1)x1+(8'^2)x0=10 (if you dont understand , google octal format.)
You really know how to explain. Great, please continue.
I have a question: Which programmer do you recommend for programming the Arduino Nano? Please supply a link. Thanks in advance.
Can you make a tutorial on how to push data from these nodes to cloud for iot use
may be u could send the data serially to a raspberry pi then upload it to the cloud,, or add one node that connects to the cloud directly
Sir can u plz tell me the single line of program that can send the data for maximum distance while using nrf24l01+pa+lna in multiple nodes network.
Please make a video about how to make wireless cat6 transmitter and receiver
thank you sir for this excellent video,
but its not working when i checked for Node 00 and Node 012 and when i does not connected other nodes (when i want to on or off led of NODE 012 controlled by Node 00)
please help me sir
shubham jaiswal have you fixed? I think it need node01 online act as a router in case node012 too far away
great content an super animation/video editing
sir can i write code like (radio.write(main_node, &customKey, sizeof(customKey));)
Can we connect node 01 directly to node 02, so that every successful step in the tree the nodes are connected to each other to reduce traffic through the central node?
Thanks for clear expanatios how to build or install the sencor..
Priceless
Awesome video going to use soon
Hi sir, do you think that it possible 30 tx trasmit to 1 receiver? if more than one tx in simultaneous will be lost data? Thanks so much

In this case you can just use the rf24 library; your application does not need the mesh network.
Great work! Thanks
Great video!
Can this topology behave like an extender? For the example, sending data from node 011 to node 01, then forward it to master 00?
pretty sure it can
but all the correct modules will need to be powered and in range so it wont be like 01 to 0122 without first going thro 012
if i use nodemcu for this project, can u show how make if use nodemcu
please
Please make vedio on gas sensor
hi, great videos! can you please tell what software you use for animation?
Useful video. Excellent
Can i use this method for multihop communication?
I'll make transfer data from node to master, with node is much

hi, if i use an nrf2401 with antenna as transmitter paired with a simple one as receiver , i will get the maximum 1km range comunnication ?
so you can communicate between 3125 NRF at the same time ??
so one NRF can send information to 3124 NRF in the same time ??
Can we use multiple nodes with same address in a network? Actually, my requirement is to send same data to all (up to 20) clients a time and all clients has to send data to master individually.

SOOO NICE !!! this is a great video !
Thanks!
Two set of network nrf24 overlapping, if node00, node01, node011 same.
Is there any unique pipe address as nRF24 ?
Kindly help
Do you believe a bluetooth module can be added to the Base micro controller to send and receive the data from an android phone ?
How can i connect two NRF as receivers with single arduino uno connected with single TX ?
I bought knockoff modules. They lack certain features. Where did you buy yours?
Can u make a video on how to push data from these to cloud
Hello and congratulations for your videos.
I'm a newbie.
I need to receive information from two sensors on two different cards: I can't diversify the two packages on the receiving card and the result is that I receive only one.
How can I do?
Thank you so much - excellent work!!!
Thanks!
Can this same thing done by node mcu using wifi without nrf24l module?
Any chance to have a UA-cam video using the SAMD processor instead of the AVR? Currently, the RF24Network doesn't work with any of the faster SAMD boards which are nice to use when using TFT displays for all the nodes in the network.
Hey, no, not in near future.
Sir i want to make address of five digit Integer number
like-
this_Node = 31211 :
Node1= 31222 :
So, What i have to do sir
or what are the changes i have to do,
How many nodes Could I have In a Mesh Topology?
I prefer to use Pcbway because they can check my design files mantually and help fix the small design error. So PCB always works perfectly and Fab quality is flawless. Moreover, there is no difference for me between $5 and $2.
Excellent carry on
Excellent video, would you be able to expand the tutorial to discuss the rf24mesh library?
Thank you! That's a good suggestion but currently I have quite a big do-to list with other projects and tutorials, so it would take me some time to get to this one. Cheers!
What can the range be if we need to communicate between base 00 and base 01111
verry nice now i get it thanks
