nrf24LE1 I2C pin resistor

Hello,

I have a problem with getting i2c to work. What I did is enabled the 2-wire block, and tried to send various data as a master(by setting the registers), but I cant measure any chnage on SDA or SCL lines with logic analyzers. I am using 10k pullups on my PCB.

I also tried to program this example as a i2c master, devzone.nordicsemi.com/.../, but again nothing on SDA or SCL. But I am able to communicate with two sensors ,that I have on the same board as the nrf24le1, with the use of arduino.

Any ideas please? Are there already any resistors on the W2SDA and W2SCL pins?
