[Question] Replacing RFM69 with NRF24L01

[static]

Good evening all!
I've been following Eric's progress with the Uber setup since it was mentioned on hackaday.com, and finally have gotten to a point where I can actually start tinkering with it.  I saw the thread with discussion of the various merits of different wireless radios, but I haven't been able to find anything in regards to actually switching radios.  A year or so ago I purchased a large quantity (20+) of NRF24L01 radio modules from some .hk site with the help of Google translate, and I'd really love to use those for home automation rather than buying RMF69s at 5 or 6 bucks a pop when I have them on hand.  My experience with design is almost entirely in hardware, so maybe it's easy, maybe it isn't.  I don't really understand the wireless transmission on a low enough level to recode the entire node sketch, but if it's as easy as adjusting a few things and dropping in the NRF library instead, I could have some serious deployment happening.

tl;dr, Does anybody know how hard it would be to use NRF24L01s with this setup instead of RMF69s, and/or has already done this and would be willing to share their code or give me a few pointers?

Thanks!

I'm looking for this as well. I have managed to get the arduino and RasPi talking with the nRF24L01+ as I am attempting to take the Ethernet Shield out of the picture. (tutorial I used for this: blog.riyas.org/2014/08/raspberry-pi-as-nrf24l01-base-station-internet-connected-wireless.html)

I also have an abundance of the nRF24L01+ as I ordered from China and am working on getting this going. As noted in Step 16 of the instructable, someone has been working on the library to avoid using the arduino all together as a gateway and only use the RasPi, which is what I am working on as well for the nRF24L01+'s.

If you're committed to using nrf24l, I'd recommend you check out the MySensors.org site.

Thanks DemonDreamer.. I have moved on over to that site and so far am having some good luck.

I just wanted to report back that I am successfully communicating with the nRF24L01+'s using Arduino Uno with Ethernet Shield(Gateway), Arduino Nano 3.0(sensor) and RasPi(openHab) using the information I obtained fro the link DemonDreamer provided.

Later this week or weekend I will be putting together a tutorial and providing all the code via github.

Thanks again DemonDreamer!!

Wow, that was fast!  Looking forward to your writeup for sure.  And yes, thanks DemonDreamer!  That site was actually enormously helpful.  I need to start compiling a list of sites that are helpful on various Arduino topics, as I honestly spent a lot of time searching before posting here and never ran across that particular resource.

Hi Puregrain, I am also interested in using nrf24l01 modules. Is your code posted anywhere?

I also build MQTTEthernetGateway from mysensors.org, but I am absolutely not happy: the gw gets stuck after a while, I have to setup Mosquitto to be able to use other libraries than MySensors library and I was not able to bridge MQTTEthernert Gateway and Mosquitto. Mysensor is just not stable and poorly documented, you have to dig deep in the forums to get the information you need.

So I went back to this place here, hoping someone will just edit the code for using nrf24l01, I´m to dumb to get it to work all by myself...
