n Circuit Assembly
Repeat!
Since these are radio modules, you’ll need
at least two
modules to talk to
each other. Duplicate the connections between another Redboard and
n module. Don’t forget to attach the antenna to your n
if you have the RP-SMA version.
Arduino Code
There are a lot of libraries available for this module, but we recommend
using the RF24 library, originally written by maniacBug, and updated for
Arduino 1.6x by TMRh20.
You can find the most up-to-date version of the library here. Alternatively,
you can download this zip and install it into your Arduino IDE libraries
folder. If you need help with the library installation, please check out our
tutorial.
DOWNLOAD THE RF24 LIBRARY
Once you have your code properly installed, open up
Examples
→
RF24
→
GettingStarted.ino
.
Check out the User Configuration section of the code, and make sure you
update yours as shown below.
/****************** User Config ***************************/
/*** Set this radio as radio number 0 or 1 ***/
bool radioNumber = 1;
/* Hardware configuration: Set up nRF24L01 radio on SPI bus pl
us pins 9 & 10 */
RF24 radio(9,10);
One radio should have the
radioNumber
set to
0
and the other should be
set to
1
.
Upload the code to your Redboards. Once you have them both set up, you
can open up two terminals set at 115200 bps, 8-N-1, and you should see
the following appear on the terminal.

*** PRESS 'T' to begin transmitting to the other node
Press
T
in one terminal, press
R
in the other, and wait until you start
seeing your radios communicating! You should see something similar in
your terminal.
