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. For example:
n test
n EIO transfer aborted
n ECONNRESET user aborted transfer
n EEXIST already exists
n EINVAL invalid command
n EINVAL invalid name
n EINVAL invalid parameters
n EIO I/O failure
n EISDIR path is directory
n ENOBUFS buffer allocation failed
n ENODEV volume offline
n ENOENT does not exist
n ENOSPC file system full
n EPERM cannot overwrite dest
n EPERM not a secure file
n EPERM secure file
n ETIMEDOUT timed out
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 CDdirectory
Changes the current working directory todirectory. Prints the current working directory or an error
if unable to change todirectory.
