[nRF52805] ble app uart + I2C + LIS3DH Acc Output X,Y,Z values from LIS3DH 0!!!

Question

values returned by ACC is always 0 !! 
 shema hardware LIS3DH :

shema hardware NRF52805 && LIS3DH :

twi initi: 
 #define PIN_SCL NRF_GPIO_PIN_MAP(0, 16) // SCL signal pin #define PIN_SDA NRF_GPIO_PIN_MAP(0, 18) // SDA signal pin 
 
 I was based on this link NRF52840: 
 iamjustinwang.blogspot.com/.../nrf52840-ble-app-uart-i2c-lis3dh-acc.html 
 Please help me to fix this. Also, If you think any other approach is simple and efficient, please let me know. Im open to suggestions.

[nRF52805] ble app uart + I2C + LIS3DH Acc Output X,Y,Z values from LIS3DH 0!!!
