CONFIG_FS_MGMT_MAX_OFFSET_LEN

(No prompt – not directly user assignable.)

Type: int

Help

Maximal byte length of encoded offset/size, within transferred CBOR frame containing chunk of downloaded file. This value affects how much of data will fit into download buffer, as it selects sizes of fields within headers. NOTE: This option is hidden intentionally as it is intended to be assigned from limited set of allowed values, depending on the selection made in FS_MGMT_MAX_FILE_SIZE menu.
