Invalid: Obscure wlan scan bug?
this.wiederkehr last edited by this.wiederkehr
I'm facing obscure wlan bug. After deinit'ing the wlan, subsequently init'ing it and performing a scan, I rarely do find the wlan's I'd expect. This was not a problem when I did not deinit the wlan at all.
This does cause the problem:
form network import WLAN wlan = WLAN() wlan.deinit() wlan.init(mode=WLAN.STA) wlan.scan()
There is an unresolved issue which might be related:
Is anybody aware of similar issue? Is there a workaround?

here you are:
(sysname='LoPy', nodename='LoPy', release='1.15.0.b1', version='v1.8.6-849-baa8c33 on 2018-01-29', machine='LoPy with ESP32', lorawan='1.0.0')
Forget about my code above. I thought this is the problem but it's not. Actually my board freezes when doing wlan operations. However I'm not able to reproduce with a minimum example...
Just forget about it. I'll report back once I have a minimum example which shows the issue ...
Sorry for bothering ...

What device and what firmware version are you running? You can check by running the following:
import os print(os.uname())
When I ran the following code on a LoPy with the latest firmware, this worked as expected:
from network import WLAN wlan = WLAN(mode=WLAN.STA) print(wlan.scan()) wlan.deinit() wlan.init(mode=WLAN.STA) print('===================') print(wlan.scan())
