The problem with ESP board spurious reset happens at disconnect time on Windows (clearing DTR before RTS triggers a reset). Previous workarounds tried to detect possible ESP boards and apply the correct DTR and RTS settings when opening the port. Instead, we can manually clear RTS before closing the port and thereby avoid the reset issue. Opening the port can keep the default behaviour (RTS & DTR both set). close() is called from a finally block in the mpremote main module (via do_disconnect()) - so this should always happen provided the Python process isn't terminated by the OS. One additional workaround is needed to prevent a spurious reset first time a Silicon Labs CP210x-based ESP board is opened by mpremote after enumeration.

mpremote -- MicroPython remote control
This CLI tool provides an integrated set of utilities to remotely interact with and automate a MicroPython device over a serial connection.
The simplest way to use this tool is:
mpremote
This will automatically connect to a USB serial port and provide an interactive REPL.
The full list of supported commands are:
mpremote connect <device> -- connect to given device
device may be: list, auto, id:x, port:x
or any valid device name/path
mpremote disconnect -- disconnect current device
mpremote mount <local-dir> -- mount local directory on device
mpremote eval <string> -- evaluate and print the string
mpremote exec <string> -- execute the string
mpremote run <file> -- run the given local script
mpremote fs <command> <args...> -- execute filesystem commands on the device
command may be: cat, ls, cp, rm, mkdir, rmdir, sha256sum
use ":" as a prefix to specify a file on the device
mpremote repl -- enter REPL
options:
--capture <file>
--inject-code <string>
--inject-file <file>
mpremote mip install <package...> -- Install packages (from micropython-lib or third-party sources)
options:
--target <path>
--index <url>
--no-mpy
mpremote help -- print list of commands and exit
Multiple commands can be specified and they will be run sequentially. Connection and disconnection will be done automatically at the start and end of the execution of the tool, if such commands are not explicitly given. Automatic connection will search for the first available serial device. If no action is specified then the REPL will be entered.
Shortcuts can be defined using the macro system. Built-in shortcuts are:
- a0, a1, a2, a3: connect to
/dev/ttyACM? - u0, u1, u2, u3: connect to
/dev/ttyUSB? - c0, c1, c2, c3: connect to
COM? - cat, ls, cp, rm, mkdir, rmdir, df: filesystem commands
- reset: reset the device
- bootloader: make the device enter its bootloader
Any user configuration, including user-defined shortcuts, can be placed in .config/mpremote/config.py. For example:
# Custom macro commands
commands = {
"c33": "connect id:334D335C3138",
"bl": "bootloader",
"double x=4": {
"command": "eval x*2",
"help": "multiply by two"
}
}
Examples:
mpremote
mpremote a1
mpremote connect /dev/ttyUSB0 repl
mpremote ls
mpremote a1 ls
mpremote exec "import micropython; micropython.mem_info()"
mpremote eval 1/2 eval 3/4
mpremote mount .
mpremote mount . exec "import local_script"
mpremote ls
mpremote cat boot.py
mpremote cp :main.py .
mpremote cp main.py :
mpremote cp -r dir/ :
mpremote sha256sum :main.py
mpremote mip install aioble
mpremote mip install github:org/repo@branch
mpremote mip install gitlab:org/repo@branch
