nRF24LU1+: Erasing pages does not work

I'm trying to erase the page 32 of a nRF24LU1+ via SPI (using a Bus Pirate).

What I did so far:

  1. Display the first 16 bytes of content of page 32: 0x03 0x40 0x00 0x10
  2. Enable writing flag (WREN): 0x06
  3. Check if setting the write flag was successful: 0x05 0x01
  4. Erase page nr. 32: 0x52 0x20
  5. Display the first 16 bytes of content of page 32: 0x03 0x40 0x00 0x10

Result: The content is still there. Also the WREN flag is still enabled.

What did I do wrong? Did I miss something obvious? Is the chip really a nRF24LU1+? The marking says "NRF 0 LU1PA 1410NR".

Any help is welcome!
