I try to read the data from the inertial unit with frames of different size for this I need to read the data via the STM32F446 uart, but the functions available with HAL uart do not allow it.

It should allow you to collect at byte at a time.

For example using HAL_UART_Receive_IT() for a one byte buffer in the callback.

The HAL implementation is a bit obtuse, if it gets in your way, limit how you use it.

It is possible to mix coding styles, and to implement your own wrappers around the library internals.
