What could be happening is that opening the device in pyserial does something with the hardware handshake lines that causes the microcontroller to reset, hence you get the boot output on every new connection. (I don’t know the details offhand about how to configure that in pyserial and how the usual...

By “no longer have access to the REPL”, do you mean that you explicitly detached the UART from stdin/out (using dupterm )? Because if not, you can just send a control-C through the UART and that will break out of your infinite loop and drop you in the REPL – same as in CPython on the desktop. And ye...

I don’t know if there is a better “consolidated place” – I usually just use the search function of the documentation – but the WLAN auth modes are documented at WLAN.scan() , and one can assume that they are the same for WLAN.config() . The documentation there just states “see module constants”, whi...

Can you post the full link to the guide you used? Abbreviated like this it’s not much use. (I’m confused because I’m not aware of any official release of MicroPython for SAMD21 yet. Any reason why you want MicroPython, not CircuitPython on that board?) Are you sure tty.usbmodem411 is the right port ...

Or a NumWorks , which even comes with source code for both firmware and hardware. Unfortunately I don’t know the answers to your questions because I stopped pursuing them myself after I got the NumWorks (which I haven’t done much with either). I suspect you are going to have some trouble adapting Sc...

So, you don’t want the ESP to act as a mass storage device, but you want it to use another mass storage device? Regardless, that won’t work either due to the missing USB. I’m not sure if any MicroPython platform has drivers for that, even those that do have USB. Assuming that your RS232 interface is...

There is, if you want to rebuild the firmware (it’s done in ports/esp8266/modules/inisetup.py called from _boot.py), but I’m not sure you need to – you can just disable it on the REPL after flashing, and it will stay off.

Did you make more progress with https://github.com/micropython/micropython/pull/3034#issuecomment-492205467 This sounds like it would be really useful for the device-initiated case described here? Yes, you are right, if the PC can be online all the time that could be used too. No, I haven’t spent a...

If you can live with initiating the transfer from the PC side (it sounds like you want the opposite), the WebREPL is the easiest way to transfer files wirelessly from and to ESP boards, using either the HTML or command-line client. If you need to initiate the transfer from the microcontroller side, ...
