File system commands

To access the file system, Enter Command mode and use the following commands. All commands

block the AT command processor until completed and only work from Command mode; they are not

valid for API mode or MicroPython's xbee.atcmd() method. Commands are case-insensitive as are file

and directory names. Optional parameters are shown in square brackets ([]).

FS is a command with sub-commands. These sub-commands are arguments to FS.

For FS commands, you have to type AT before the command, for example ATFS PWD, ATFS LS and so

forth.

Error responses

If a command succeeds it returns information such as the name of the current working directory or a

list of files, orOKif there is no information to report. If it fails, you see a detailed error message

instead of the typicalERROR response for a failing ATcommand.The response is a named error code

and a textual description of the error.

Note The exact content of error messages may change in the future. All errors start with a capital E,

followed by one or more uppercase letters and digits, a space, and an description of the error.

If writing your own AT command parsing code, you can determine if an FS command response is an

error by checking if the first letter of the response is capital E.

ATFS (File System)

When sent without any parameters, FS prints a list of supported commands.

ATFS PWD

Prints the current working directory, which always starts with/and defaults to/flashat startup.

ATFS LS [directory]

Lists files and directories in the specified directory. Thedirectoryparameter is optional and defaults

to a period(.), which represents the current directory. The list ends with a blank line.

Entries start with zero or more spaces, followed by filesize or the string<DIR>for directories, then a

single space character and the name of the entry. Directory names end with a forward slash (/) to

differentiate them from files. Secure files end with a hash mark (#) and you cannot download them.
