CFA835 pull up resistor for SPI data ready signal

Hi,
I've connected CFA835 to Arduino uno using SPI interface and running CFA835-I2C-SPI-Example. The code times out on receive data, since SPI data ready stays high. The logic analyzer confirmed it too. I've tried [10K - 100K] Ohms range for pull up resistor without any success.
What is the recommended pull up resistor for SPI data ready signal?

Thanks,
Reza

Hi Reza, We would have recommended 100kOhms, so I'm surprised to hear that didn't work for you.

Could you submit this problem to our support ticket system (email support@crystalfontz.com)? That will ensure you get a response back
