Raspberry Pi I2C setting

I want to use raspberry pi's I2C, but there is something wrong.

I checked raspberrypi property and condition was shown as follows.

DeviceAddress: 192.168.3.27

Port: 18734

BoardName: Raspberry Pi 3 Model B

AvailableLEDs: {'led0'}

AvailableDigitalPins: [4,5,6,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27]

AvailableSPIChannels: {'CE0','CE1'}

AvailableI2CBuses: {'i2c-1'}

AvailableWebcams: {}

I2CBusSpeed: 0

i2c-1 is enabled, so I used scanI2CBus as folllows

scanI2CBus(mypi,'i2c-1')

The answer is as follows, adress was not shown.

ans =

uint8

0

If anyone know how to solve this problem, please tell me.

Are you connecting any I2C device to your Raspberry Pi? What device are you connecting?

scanI2CBus only detects the address of the I2C device when I2C device is connected.
