WebREPL setup fails in PicoW when no boot.py exists on device

bug

import webrepl_setup fails by default unless the user happens to have created a boot.py file on device. Creating an empty boot.py makes import webrepl_setup succeed and ask for a password and reboot.

Pico W
MicroPython latest release 1.20

Getting WebREPL running on my PicoW had a ton of user friction, we need to make it so it's a lot more straightforward, perhaps by enhancing webrepl_setup to ask if they want to auto connect to WiFi, and ask for SSID/pass. Since WebREPL is useless without a WiFi connection.

I'm able to connect to serial REPL, but when I attempt to import webrepl_setup it raised an ImportError

is there no webrepl for ESP32?

Assessment

Q Qwen · high

Both issues concern the webrepl_setup module, but they describe fundamentally different problems. Issue #11661 is about WebREPL setup failing on Pico W specifically when boot.py doesn't exist, with a request for interactive WiFi configuration. Issue #3579 is about the webrepl_setup module not being present in the ESP32 firmware build at all (ImportError: no module named 'webrepl_setup'). The root causes are different: one is a runtime behavior issue dependent on boot.py existence on RP2, the other is a build configuration issue where the module wasn't included in the ESP32 firmware. They share the webrepl component but address different bugs on different ports.

Suggested action

Keep both issues open as they address different problems. Issue #11661 should be tracked for the Pico W boot.py dependency and interactive WiFi setup enhancement. Issue #3579 should be investigated for ESP32 build configuration to ensure webrepl_setup is included.
