stm32f407 USB CDC FS multi-packet transfer

[DKola.1]

how to transmit data buffer without splitting? Im using HAL library and it says its allowed to send multi-packet without splitting, but when i try to send data to PC it splitts into max packet size that is 64 byte size

Only Chuck Norris could do this. But he's retired now...

Max packet size for FS is 64 bytes. HAL can send a buffer larger than 64 bytes in one command, but it does so by breaking them up. I don't think it's claiming otherwise.
