How to setup I2C

[TVoge]

I am trying to connect the VL53L1X distance sensor to a B-L072z-lrwan dicoboard so it can send data using the lorawan stack .

This is my first project using a hal and i cant get the I2C connection working.

The output to my serial monitor is: 536872016,status

My code right now:

GPIO init

static void MX_GPIO_Init(void)
{
  GPIO_InitTypeDef GPIO_InitStruct = {0};
 
  /* GPIO Ports Clock Enable */
  __HAL_RCC_GPIOB_CLK_ENABLE();
 
	GPIO_InitStruct.Pin = GPIO_PIN_9;
	GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
  GPIO_InitStruct.Alternate = GPIO_AF4_I2C1;
  HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
 
	GPIO_InitStruct.Pin = GPIO_PIN_8;
	GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
  GPIO_InitStruct.Pull = GPIO_NOPULL;
  GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_VERY_HIGH;
  GPIO_InitStruct.Alternate = GPIO_AF4_I2C1;
  HAL_GPIO_Init(GPIOB, &GPIO_InitStruct);
 
}

I2C init:

static void MX_I2C1_Init(void)
{
  hi2c1.Instance = I2C1;
  hi2c1.Init.Timing = 0x00300F38;
  hi2c1.Init.OwnAddress1 = 164;
  hi2c1.Init.AddressingMode = I2C_ADDRESSINGMODE_7BIT;
  hi2c1.Init.DualAddressMode = I2C_DUALADDRESS_DISABLE;
  hi2c1.Init.OwnAddress2 = 0;
  hi2c1.Init.OwnAddress2Masks = I2C_OA2_NOMASK;
  hi2c1.Init.GeneralCallMode = I2C_GENERALCALL_DISABLE;
  hi2c1.Init.NoStretchMode = I2C_NOSTRETCH_DISABLE;
}

ranging function

void AutonomousLowPowerRangingTest(void)
{
	static VL53L1_RangingMeasurementData_t RangingData;
	//PRINTF("Autonomous Ranging Test\n");
		  status = VL53L1_WaitMeasurementDataReady(Dev);
			if(!status)
			{
				status = VL53L1_GetRangingMeasurementData(Dev, &RangingData);
				//status =0;
				PRINTF("%d,status\n");
				if(status==0){
					
					PRINTF("%d,%d,%.2f,%.2f\n", RangingData.RangeStatus,RangingData.RangeMilliMeter,
									(RangingData.SignalRateRtnMegaCps/65536.0),RangingData.AmbientRateRtnMegaCps/65336.0);
				
					}
				status = VL53L1_ClearInterruptAndStartMeasurement(Dev);
	
				}
//  return status;
}

After measuring the SCL and SDA on an osiloscope i found out that they are both set to 1.
