I managed t get two arduinos communicating whit each other via the nrf24L01+. Now im wondering if is it possible to send whit some android app a wifi signal, that arduino would read and turn on/off home lighs, gates, or someting. I dont wanna use ethernet shield and local server, i just need to know if its possible to communicate from my phone directly to arduino.
Thanks in advance
There is no NRF24L01 (protocol) support in smartphones, so it will not work.
So is there any other way to communicate DIRECTLY from phone to arduino? I wish to open my front gates, garage gate and front lights via my phone(30m distance, 2 solid concrete walls in beetwen)?
Or is only way to set up a server and communicate through it?
Bluetooth could be used for a direct connection (if smartphone implies Bluetooth),
but over 30m with walls... I doubt it (would be hard for an NRF24L01 too).
well nrf24l01+(whit atnenna) worked whit another one on tested distance of 110 meters (whit around 10% data loss, which i fixed whit repetitive sendings and quality check) and around 40 meters whit a whole house in beetwen. But whit phone wifi it probably wouldnt yea. I will look into bluettoth options.

The ESP8266 Arduino compatible WiFi module might make more sense for this application than the NRF24L01. Assuming you have a WiFi network covering your nodes, it will speak a protocol compatible with your smartphone.
The NRF24L01 approach would require something to translate between its packet protocol and WiFi as available on the smartphone.

thanks, i wil lcheck it out if it works via my arduino and smartphone and if it does, i will be moving to atmell AVr and this wifi module and hopefully i manage to make it work :DD

Nrf do other chips as well.
Do you know of a comparison chart anywhere that compares which chips do what please.
This NRF

This NRF version:
has about 800-1000 meters range in open view. And at only 3€ price is a ver good idea if you need to wirelessly communicate two diferent microcontrolelrs or arduinos.
you can use NRF24l01 directly with smartphone

good look
