STM32 I2C bootloader issue

hi all,
 I have a program to use a USB2I2C bridge to program the STM32L4 via I2C protocol.
Now I face a problem when I try to implement the protocol. When I send "Get"(0x00, 0xff), I can receive the NAK.  But I cannot receive any other data.

anyone try this I2C bootloader before?  I check the stm32flash, but not many hints from that.
thanks
