No data from magnetometer on MPU9255

I have a problem with reading data from the magnetometer on an MPU9255. The accelerometer and gyroscope work properly, but I do not receive any data from the magnetometer. I am working on the STM32F103 target.

Has anyone any idea what is wrong with code below?

uint8_t Settings = 0x00;
uint8_t SettingsM = 0x00;   
uint8_t SettingsL = 0x22;   //mode2 16bit 
//settings accelerometer and gyroscope
HAL_I2C_Mem_Write(&hi2c1, 0xD0, 27, I2C_MEMADD_SIZE_8BIT, &Settings,1,1000);
HAL_I2C_Mem_Write(&hi2c1, 0xD0, 28, I2C_MEMADD_SIZE_8BIT, &Settings,1,1000);

//Power Down mode
HAL_I2C_Mem_Write(&hi2c1, 0x0C, 0x0A, I2C_MEMADD_SIZE_8BIT, &SettingsM,1,1000);
HAL_Delay(100);
//16 bit output mode 2
HAL_I2C_Mem_Write(&hi2c1, 0x0C, 0x0A, I2C_MEMADD_SIZE_8BIT, &SettingsL,1,1000);

You need to enable the I2C bypass mode on the MPU9255 to communicate with the AK8963 directly. Set the BYPASS_EN bit in the INT Pin / Bypass Enable Configuration register (register 55) at the beginning of your program with:

uint8_t BypassEnable = 0x02;
HAL_I2C_Mem_Write(&hi2c1, 0xD0, 55, I2C_MEMADD_SIZE_8BIT, &BypassEnable,1,1000);
