RPi as a 'node'?

[Bens]

Hi Skywatch,

Not sure you are still looking into this.
It can be done, and I have done it. Actually, all the documentation is there.
You can directly connect the radio to the Pi2 and you could modify the PiSerialGateway not to act as a gateway, but simply use the sending part.

@Bens
Do you have a link to the documentation, please?

I'm also interested in the link

Ok - long delay I know, but I am now looking at this again.

Any updates out there?

I'm not sure if anyone has actually tried it, but according to the documentation you can follow the instructions for creating a raspberry pi gateway, and turn it into a node by adding

 --my-gateway=none

It would be interesting to hear what your use cases are. Wouldn't it be easier to send data over the rpi's network connection?

Thanks for the fast reply!

As you know I am still on a learning curve with this, but getting more focused as I go.

My use case would be mainly to use a raspberry pi zero attached to touch screens at various locations for display and control. I think that this approach would give the best processing bang for the buck, certainly faster at screen refersh and processing that a pro mini. More memory too for the screen as well....

Secondly I would be thinking of using pi zero with a camera and using motion detection and the possibility to send snapshot images (not sure how to implement this yet!).

@skywatch cool ideas. Thanks for sharing.

@mfalkvidd Thanks for the helpful hints! :) Theres a long cold winter to fill!

:) :) :)

I forgot to add that the pi zeros should not be on ethernet or wifi and therefore I would like to do it all via the NRF24L01+. It would probably be cheaper to use android tablets, but that would require wifi (unless anyone has attached a working nrf to a tablet?) and wifi is not that secure.
I have a lot to learn before I get to that point though! ;)
