PYB (Bundled Code Report)
You can store compiled code in flash using the
os.bundle()
function in the MicroPython REPL; refer to
the
Digi MicroPython Programming Guide
. The
PYB
sub-command reports details of the bundled code.
In Command mode, it returns two lines of text, for example:
bytecode: 619 bytes (hash=0x0900DBCE)
compiled: 2017-05-09T15:49:44
The messages are:
n
bytecode
: the size of bytecode stored in flash and its 32-bit hash. A size of
0
indicates that
there is no stored code.
n
compiled
: a compilation timestamp. A timestamp of
2000-01-01T00:00:00
indicates that the
clock was not set during compilation.
In API mode,
PYB
returns three 32-bit big-endian values:
n
bytecode size
n
bytecode hash
n
timestamp as seconds since 2000-01-01T00:00:00
PYE (Erase Bundled Code)
PYE
interrupts any running code, erases any bundled code and then does a soft-reboot on the
MicroPython subsystem.
PYV (Version Report)
Report the MicroPython version.
PY^ (Interrupt Program)
Sends
KeyboardInterrupt
to MicroPython. This is useful if there is a runaway MicroPython program
and you have filled the stdin buffer. You can enter Command mode (
+++
) and send
ATPY^
to interrupt
the program.

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 (File System)
FS
is a command with sub-commands. These sub-commands are arguments to
FS
.
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.
