How to receive variable length I2C messages?

Hello, I'm trying to write an I2C slave using HAL which can accept variable length packet sizes.  I know this question has been asked before but haven't seen any solutions yet! 

The master can send data packets of variable length - all the HAL I2C methods seem to need a 'length' parameter. 

Has anyone found a solution to this?

Could you please have a look to these examples under the STM32L4 firmware package :

• STM32Cube_FW_L4_V1.6.0\Projects\STM32L476G_EVAL\Examples\I2C\I2C_TwoBoards_RestartAdvComIT
• STM32Cube_FW_L4_V1.6.0\Projects\STM32L476G_EVAL\Examples\I2C\I2C_TwoBoards_RestartComIT
