RDA5807 noise

[ITstreet1]

Hello,

I made a barebone setup with a RDA5807 module with soldered pins, and Arduino Nano. With TEST5807M basic sketch on known frequency all I get is noise. Everything is connected ok.

The sketch output is:

What I have did wrong? Do I need pull-up resistors on I2C lines?
