Get current Wifi object

[oli]

Hi,

is there a way to get the current wifi-object? if i start the wipy and connect to it, i can login via telnet. but how to get current wifi-object to get my ipaddress, and can send network packets and stuff like that...

thanks in advance!
Regards
Oli

The new API doesn't allow to get objects without re-initializing them, but I've been thinking for a while that perhaps WLAN could make an exception in this area, since it's always enabled and because it is a "system" feature of the WiPy.

However:

Code: Select all

If you can connect via telnet, you already know the IP address, don't you?

To send network packets you just use sockets as normal. You don't need to know the network adaptor object.

But if you did want to have access to the network object then you can save it to a global variable when it's first created in boot.py.

Imagine the scenario where your boot.py changes WLAN mode to station, configures a static IP and then connects to your home router, this way you know the address and you can telnet. You also need to be able to soft reset the board, and keep the connection alive, but, boot.py runs after the soft reset, so WLAN will be reconfigured and you will be disconnected. One way to sort it out is:

Code: Select all

import machine
from network import WLAN

wlan = WLAN()
if machine.reset_cause() != machine.SOFT_RESET:
	# init as STA, set static IP and connect
	wlan.init(mode=WLAN.STA)
	...
else if not wlan.isconnected():
	wlan.connect(...)

But for this we need a way to retrieve the existing WLAN object...

Ok. I guess the same applies to USB objects as well.

Yes, probably.

+1 for a way to get the current wifi object. I was hoping to setup exactly what you suggested where you don't drop the connection across soft resets.

Already implemented in: https://github.com/micropython/micropyt ... a5c513c9a7

I will release a new software version, end of this week. BTW docs are up to date now (for the most part): http://micropython.org/resources/docs/en/latest/wipy/

This is great! Thanks for the hard work. You might want to remove the link to the GitHub wiki page from http://forum.micropython.org/viewtopic.php?f=11&t=713 now.
