of the fixed body part, and +1 if there's a dynamic part - there're 3 types of dynamic blobs with uint16_t offset/uint16_t size with uint16_t offset/uint32_t size with uint32_t offset/uint32_t size /* aligned to 8 bytes */ - strings are transmitted in UTF-16 with no termination and packet into a uint16/uint16 blob metze (This used to be commit 79103c51e5c752fbdb4d25a0047b65002828df89)
