OSError: [Errno 1] EPERM

[FlydGitHub]

Hi Can anyone help with a wifi error?

OSError: [Errno 1] EPERM

The context is line 15: wlan.connect(ssid, password)

I have tried everything to fix this without success.

My platform is the 2040 Challenger NB - 8MB,

Thanks

EPERM looks like a Windows error not Micropython. Try:

try:
    wlan.connect(ssid, password)
except OSError as error:
    print(f'error is {error}')

Thanks Dave,

Now I get:

%Run -c $EDITOR_CONTENT
error is [Errno 1] EPERM
waiting for connection...

Line 50:

raise RuntimeError('network connection failed')

Have never seen a RuntumeError() but then again I haven't used the Pico. Seems different to the many problems I have had connecting to WiFi on the ESP32.

Are you running an IDE and also what editor are you using?

[FlydGitHub]

1. Thonny - current version
2. Mac
3. The Challenger has 8MB and wifi is provided by an onboard ESP8285 chip for wifi

Which Micropython image are you running?

Show us the full wifi connect method.

These devices will start in the AP mode.

For a bullet-proof connect script see here:

and wifi.py

import network
import secrets
import time
import urequests
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect(secrets.SSID, secrets.PASSWORD)
print(wlan.isconnected())
astronauts = urequests.get("http://api.open-notify.org/astros.json").json()
number = astronauts['number']
for i in range(number):
print(astronauts['people'][i]['name'])

3. I see a consistent issue with MP, I install a module, and it still companies it's not found, eg in this case 1st line network

Ŷour board seems not directly to be supported by MicroPython. And if you use the standard RP2040 firmware, then there is not network module. RP2040 boards with WiFi support are e.g. the Pico W board or the Arduino Nano RP2040 connect. Does Challenger supply a MicroPython compatible WiFi network module for your board?

[FlydGitHub]

The claim is the the Challenger supports both MicroPython and CiriutPython

[robert-hh]

I looked at their web site, and it's a typical marketing claim. Yes, they support MicroPython and CircuitPython. But they do not tell to which extend. No word about WiFi and MicroPython or CircuitPython.

Thank you Robert, I very much appreciate you checking out there website.

I was interested which WiFi module they use. It's based on a ESP8285 chip with the standard espressif AT interface. They provide support for it in the Arduino libraries.
