I have a Arduino thats controlled bij a Serial cable and i am looking to change this to Wireles.
Therefore i have got two RN-XV units and two USB interfaces.
I managed to update the Firmware to version 4.41.
The first one i configured as a AP and the other one as a client.
On the AP the green led is blinking at a one second interval.
On the client is blinking much faster.
But if i send serial data to the AP cant see anything on the serial from the client.
Anny suggestions or the direction to a good tutorial.
RN-XV is not directly comparable with ZigBee module which just gives you serial connection without a cable. It's a WiFi module that allows TCP/IP connectivity. So to have a connection between two Arduinos you have to configure one of them to be the server (waiting for incoming connections) and the other to be a client (connecting to the server).
Google for the term "WiFly Arduino library" and you'll find a bunch of libraries for this chipset. Most of them support both roles (server and client) and most do their job reliably. Choose one and have a look at the examples.
