NRF24L01 + Arduino Leonardo - Not working

[Daniel Cintra Cugler]

Hi everyone,

I has just bought a NRF24L01 from eBay (http://www.ebay.com/itm/221249727728?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649).

I am trying to use the getting started example from the RF24 library with two Arduinos (UNO and Leonardo).

But I cannot make it work successfully.

I double checked the wires between the arduino and the radio.

LINE GND	Arduino pin GND		Radio pin 1
3V3	3V3		2
CE	9		3
CSN	10		4
SCK	13		5
MOSI	11		6
MISO	12		7

I've read that with arduino leonardo I need to connect the 5,6 and 7 radio pins in the ICSP (link here http://arduinoexamples.wordpress.com/2012/11/11/nrf24l01-com-arduino-leonardo-nrf24l01-with-arduino-leonardo/)

However, even doing such modifications, I cannot make the two radios communicate yet.

Do you guys have some clue what is the problem? There is something special that I need to do in order to make it working in the Arduino Leonardo?

Thanks!

Hello,

I had not previously tested with Leonardo, nor with the NRF24 module you are
using.

However apart from the SPI pins (MISO, MOSI and SCK) being on the ICSP header
and not the digital pins as you note below, the default for the SS pin on the
Leonardo is different to other Arduinos, so you would have to initialise the
NRF24 object like this:

NRF24 nrf24(8, 10);

I have now tested Leonardo successfully with this configuration and the
Sparkfun WRL-00691, and updated the documentation in new version 1.10 to
reflect this.
Cheers.

Hi Mike,

I really appreciated your hint.

I'll try to do this tonight and then I'll post here the results.

Thank you!

[Daniel]

Sorry the delay to answer this message.

Now it is working properly. Problem solved! =)

Thank you so much.

Best,

Daniel

Hello,

I am trying to use Arduino Leonardo boards and nRF24L01+ wireless moduls . I connected SPI pins on the ICSP header pins and connected CE-Pin8, CSN-Pin-10.( http://arduino-info.wikispaces.com/Nrf24L01-2.4GHz-HowTo )  In the code " RF24 radio(CE_PIN, CSN_PIN); " command changed new CE_PIN and CSN_PIN number. But it didn't work.Which library for nRF24L01+ can i use? Can you help me?

Hello,

Did you read about Leonardo connections in the NRF24 library documentation?

Cheers.

Hello Mikem;

I read about Leonardo connections in the NRF24 library documentation.But Leonardos not communicate with them. ( http://airspayce.com/mikem/arduino/NRF24/ )Correct this page tell connection Leonardo with nRF24L01 modul ?

Helo,

the documentation shows how to connect a Leonardo to a Sparkfun WRL-00691.
This is known to work.

Are you are using the Sparkfun WRL-00691?

If not, I cannot help you: the only device I have here is Sparkfun WRL-00691

Cheers.
