Notes

  • Multiple commands take a 16-bit Path ID, which allows the use of relative pathnames (using "/" as the path separator and using ".." to refer to a parent directory) as command parameters. The default of 0x0000 refers to the root directory (/). See the Get Path ID - 0x1C command for details on creation and use of temporary values in order to use relative pathnames.

  • For the Directory Open - 0x11 and Get Path ID - 0x1C commands, using an empty Pathname field is equivalent to using "." – both refer to the directory designated by the Path ID.

  • Local File System Request - 0x3B and Local File System Response - 0xBB Response describe the frame contents starting with the File System Command field (and excluding the Checksum field).

  • Local File System Response - 0xBB lists the fields following the Status byte when 0 (indicating a successful operation), and is only listed for commands with additional fields after the Status byte.

  • See Local File System Response - 0xBB for non-zero (error) Status values in the Response.

  • Variable-length names are NOT null terminated. The frame length determines the length of the field.
