SPI problem using nrf 24l01+ modules and SD log Shield

Hi all,

I'm new here :slight_smile:

Here is my problem : i'm using
-2 arduino mega 2560
-2 nrf 24l01+ modules
-1 SD log shield (this one http://snootlab.com/shields-snootlab/86-memoire-fr.html)

I had to make a little change on my SD shield because i'm using a mega : in order to divert SPI pins (10 11 12 13 on the SD shield vs 53 51 50 52 on the mega), i followed this link: http://forum.snootlab.com/viewtopic.php?f=30&t=134 .

Nrf 24l01+ modules also use those pins, and here comes my pb:

When I plug pins (module nrf + SD) excepted SD SCK pin, it works fine for the RF module (of course SD can't initialize).

// RF Arduino SD
//GND GND
//3V3 3V3
//CE 53 10
//CSN 48
//SCK 52 unplugged
//MOSI 51 11
//MISO 50 12

But when i plug the whole pins the RF module can't communicate with his pair...
Maybe it is something Master/Slave related?
Do you know that kind of problems?

Thank for your help!

Thanks to your links I know quite a bit about the SD logger shield. How about that other device nrf 24l01+? Need a link to that.
