nRF52832 and mpu6050

[cd.barahona]

I am trying to program mpu_simple https://github.com/Martinsbl/nrf5-mpu-examples with Segger, and I get to connect sensor MPU6050 to my board but I do not receive datas of sensor.

I have configured Segger with the device and twi. The code is this:

Can you tell me why I do not receive any datas of sensor MPU?
