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!

[cappedpluto]

you have no idea how much this helped me, i had almost given up on trying to figure this out

[drumminjeff]

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!

[Arrowtake]

Thank you for very clear explanation on how to create network of multiple NRF2401's Learned alot!

[dacelo]

You made it pretty simple! I was very confused from this library till now. CONGRATS!

[webslinger]

Wow! I've been waiting for something like this. Thank you!

[HaiTHaMKoBeIssI]

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

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! 😀

I gave a "like" and I suscribed. Thank you very much for this amazing tutorial. It is so helpful.

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.

Thank you. this video is the best! Wish you all the luck in your life

[capiberra]

Excellent tutorial! Very well explained. Thank you

[Sailingon]

this is excellent im going to make something not sure what but definitely something using your tutorial.

[jstro-hobbytech]

Awesome video. I have a bunch of those nrf modules

[bigpickles]

I've referred to this several times, and your code. Thanks so much, bro!

[gsambolin]

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 ?

DUUDE! awesome video and awesome example. We need more awesome dudes like you.

never success communication while using NRF on bredboard, may b the loose connection or something else, but working perfectly on PCB
