Description

Unfortunately:

ussl is missing from the MicroPython build for RP2350/Pico 2 W

So when I try:

import ussl
I get:

ImportError: no module named 'ussl'

Code Size

No response

Implementation

I hope the MicroPython maintainers or community will implement this feature

Feature request SSL/ussl Arduino Nano RP2040 (rp2)

closedby covidiumopened 2022-07-11updated 2022-07-12

enhancementport-rp2

It seems that the current build for Arduino Nano RP2040 (rp2) doesn't have ussl/SSL enabled during the build making it useless if one would like to contact a web server over HTTPS.
I was able to c/p the usocket.py file available in the micropython-lib repo, but this one will automatically try to load the ussl/ssl module for creating the requests over TLS.

Is it possible to recompile or enable the ussl/ssl module for a new build?
Thanks

Assessment

S Sonnet · medium

Both issues are feature requests for ussl/SSL support in the rp2 port, affecting the same module (extmod/ussl) and same port build configuration. The difference is hardware target: #8898 is RP2040 (Arduino Nano RP2040), #17507 is RP2350 (Pico 2 W). A port-level fix enabling SSL in the rp2 build would likely address both. However, RP2040 and RP2350 are distinct silicon with potentially different SSL/crypto implementation paths (RP2350 has hardware crypto acceleration), so the fix may not be identical. Confidence is medium rather than high due to this hardware difference.

Suggested action

Close #17507 as duplicate of the older #8898, or merge both into a single tracking issue for "enable SSL/ussl in rp2 port builds". If RP2350-specific implementation work is needed (e.g. hardware crypto), keep #17507 open and link it to #8898 as related context.
