nerfnet: Wireless Networking over nRF24L01 2.4GHz Radios

[@jirkasvitil2762]

Good job, you kinda reinspired me to continue my Lora communicator project. Thank you for inspiration.

[@bigmouthstrikesagain4056]

Could this be used to create a off grid wireless mesh net similar to the Internet?

[@cory3640]

This is awesome and has many applications, you could use this directly aside LoRa, and pass serial data to the internet.over mqtt.

[@KolibriFPV]

Awesome project, can't wait to see updates on this! Btw, if you might be interested, please try out these on LoRa modules. I've been wondering for quite a while on making a proper stable network using them. So far the main library I used for LoRa mesh is the Radiohead library, a pretty old one, yet works for the least. Yet, it just couldn't seem to provide a higher performance. Is it possible to tinker around nerfnet to be able to use LoRa? Knowing that it uses a SPI too as it's interface Cheers!

[@ArtiZirk]

This is really cool. I wonder if something similar would be possible with LoRa radio modules over long range.

[@TheResistorNetwork]

Yeah, definitely possible. I have been thinking about learning about those LoRa modules for a while now. Thanks for the comment!

[@carlosblanco5118]

I second this idea!

[@neilhendin2545]

Awesome hack -- wound up with a pack of these radios by mistake (ordered ESP8266's and got these instead)

[@TheResistorNetwork]

Haha, thanks Neil!

[@nakiradu77]

Thanks !

Firstly Thank you for making this video, I am happy to find this video over internet. I want to establish communication between Raspberry Pi 5 and PC (desktop) over RF. In this communication, simply, I want to transfer some sensor data with live video streaming from pi to PC. please guide me for this process. I am a beginner in this field. Not much knowledge about it. My project is restricted to use RF link communication. Help me please

Hello i tried it but not working Compiler problem

[@AdityaDikonda]

Hey! That’s great work, I’m in my junior year at college, and I’ve taken up a project which is very similar to this. I’ve watched your videos and still would need help. Could you help me?

[@SteveWrightNZ]

What, no PtMP??

[@UntrackedEndorphins]

What if you used two radios for each pi? one for transmitting and one for receving, would that help with anything?

[@TheResistorNetwork]

Yeah definitely. I had also considered bonding multiple nerf0/nerf1 interfaces together to improve throughput. I have started hacking on a next generation protocol that should add support for beacons, repeaters and basic routing. Still early stage but hopefully that will make it trivial to use multiple radios in parallel!

[@UntrackedEndorphins]

@@TheResistorNetwork cool! Also, are the packets encrypted? Or could anyone sniff the radios and get the data?

[@TheResistorNetwork]

@@UntrackedEndorphins They are presently unencrypted and unsigned! This means that it is possible to implement a replay/timing attack against the network as well. The next gen protocol will have flags to indicate that packets are signed but I will likely implement that later on since this is just a hobby project for now.
