Question

How do I use the nRF24LU1+ in SPI communication as SLAVE? do the SDK SPI libraries support that or only for nRF24LE1?

Hi Alon, 
 I noticed that you have duplicated the question in the support portal. I suggest that we can continue in the case in support portal. And can update it here once we finish there. 
 I quoted here my instruction, that may be helpful for others: 
 
 [i]There are few differences between nRF24LE1 and nRF24LU1+ you would need to notice: 
 
 
 SPI slave pins are not available by default, you would need to write to the P0EXP and P0ALT register to enable them as SPI slave pins. (Please refer to chapter 13 in the Spec) 
 
 
 Registers are different, please compare and find the different in name and bit desciption from chapter 18 in the nRF24LE1 Product Spec. 
 
 
 Only mode 0 is supported on the nRF24LU1+ (when in LE1 all 4 modes are supported)[/i]
