nrf51822

module costs 6.18 euro on ebay, 32 bit arm 16k sram, 256k flash!!
compatible with nrf24 radio and bluetooth smart.
I'm impressed!
Seems compatible with arm mbed, and there even exists arduino add-on ? (looks like commercial...)
I will look at existence of linux tools, will order one, and see if porting mysensor on this is easy...

Thanks a lot for this, that's exactly what I was looking for.
This is very cheap, small, and low power.
I'm still waiting to receive one to try.

Please note the existance of existing libraries including a wiring library which looks great:
https://hackaday.io/project/5794-nrf24le1-wiring-library
It is written by Justin who just posted above.
There is also a rf24.h there, I don't know if it is compatible with arduino's lib?

It seems you have made your own digitalRead/Write?

I'm still very new to all this.
I will start to setup a dev environment (ubuntu) and try to compile your stuff.

Do you plan something else?
Create a library? Is MySensor only C++? Is there a plan to create a C MySensor library?
Too bad that most MySensor examples are in C++...
Would you like to create a github repo?

Hi

I'm new to mysensors. i'm looking for ready made low cost and compact solution, and found that the nrf24le1 which has an integrated 8051 based MCU, is very very cheap and ultra low power:

Also on ebay.

It is programmed with an arduino, it has opensource compiler and library (sdcc and wiring library)

I think it could make a great sensor board, if mysensor library was ported to it.

As I don't know much about mysensor library content, maybe someone could tell if the porting effort is difficult?

Thanks
