OSError: -202

[Josverl]

OSError: -202 is an error code that indicates a failure in the getaddrinfo() function, which is used to resolve a hostname to an IP address.
This error can (will) occur when the hostname is invalid, the network is unreachable, or the DNS server is not responding.

Maybe we should add a list of the common ones to: https://docs.micropython.org/en/latest/library/errno.html

Microbit has one: https://support.microbit.org/support/solutions/articles/19000126750-python-oserror-codes

[awchen9]

After connecting to WiFi, run

import mip
mip.install('sensor')
Installing sensor (latest) from https://micropython.org/pi/v2 to /lib
Package not found: https://micropython.org/pi/v2/package/6/sensor/latest.json
Package may be partially installed

Is the URL ' https://micropython.org/pi/v2' or 'https://micropython.org/pi/v2/package/6/sensor/latest.json' incorrect.
How to solve it

[glenn20]

First, you should check and verify that your internet access on your micropython board is working. If that is working, the next thing to check is that your DNS settings are correct so that hostname lookups are working.

Note that if you dont have internet access from your micropython device, you can still mip install packages using mpremote mip install fron your computer (if your micropython device is attached to your computer via usb/serial).

Is it like this

[bixb922]

There is no module called "sensor" in the Micropython library. What module or driver are you trying to install?

The command mpremote mip install works at the command prompt of your PC, and not at the >>> prompt. Please try on your PC. mpremote is a useful utility program, see https://docs.micropython.org/en/latest/reference/mpremote.html

This is not an actual solution. However, I resolved this error on the Xiao ESP32-S3 board by downgrading the firmware to the following version:

v1.22.0 (2023-12-27)

Link to firmware: https://micropython.org/download/ESP32_GENERIC_S3/

I hope this helps folks running into this error. It took me too long to find a temporary fix for this issue.

The following thread led me to try this approach.

Hopefully, there will be another fix soon that doesn't require downgrading the firmware.
