Note that you need to logoff and log back in again (or reboot) after changing groups.

You can use the id command to confirm your group membership.

You need to surround the argument to http_get in quotes.

It should definitely be possible to do. Basically, it mostly boils down to how much memory you have. But you can use exec to execute a string containing python source code.

...For the bare-metal ports, malloc doesn't appear to exist at all. m_malloc gets mapped to gc_alloc inside the py/malloc.c file... Does that mean that, on bare-metal ports, C allocates memory from the Python heap? The python heap is the only heap available on the bare metal ports. The code would n...

Right - if you allocate something in C land (using malloc or whatever) then a pointer to that object either needs to be stored inside a python object or needs to be stored someplace in the root pointers area or the garbage collector will consider the alloced memory to be "unused" and will free it t...

Also keep in mind that the STM32F411CEU6 only has 512K of flash. The default firmware and filesystem take up 376K Due to the way the flash is laid out, this means that the only available flash block is a 128K one that starts at the 384K mark. Due to RAM memory constraints you can only use 64K of any...

Disabling the REPL won't really help you.

You can still run esptool.py and download the entire flash and then just grab stuff from the filesystem using code running on the host.

@davef posted about the WEACT and UART1, and then the post was deleted. The mpconfigboard.h file for the WEACT sets up the REPL to mirror on UART1: https://github.com/mcauser/WEACT_F411CEU6/blob/40061c9ed43dc7fb5e0363f808843ce2cda7e0e1/mpconfigboard.h#L35-L36 You'll want to comment out those 2 lines...

No. This is because there is no USB on the ESP32. It uses an external USB-to-serial chip and there is no way to get MCS through a USB-to-serial chip.
