IS someone succes to work with nrf51 board

I have got the official Nrf51 DK board with nrf51422 component.

I did not succes to make working spi with the sx1276.

WIth another board, i don't have any problem. I look to timing diagram with a logic analyser and all seems ok... but the sx1276 does not reply !

Is someone succes with a nrf51xxxx component ?

Have you check the nReset and SPI NSS pins? I see the NSS pin we use in the driver is shared with LED4, could this be the issue?

I used the pin 1,2,3,4 for spi communication as defined in some official example of the nrf51 sdk. My sx1276 works well with other board (i made a tiny test with an arduino board). Maybe i need to test my nrf51dk spi with a simple eeprom. To see if the problem is the same....

But actually timing diagram seems really identic between (arduino+sx1276) or (nrf51+sx1276). This is really strange....
