Assigning a Static IP Address at Boot Up
If the users wants their device to connect to a home router upon boot up, using with a fixed
IP address, use the following script as
/flash/boot.py
:
import machine
from network import WLAN
wlan = WLAN() # get current object, without changing the mode
if machine.reset_cause() != machine.SOFT_RESET:
wlan.init(mode=WLAN.STA)
# configuration below MUST match your home router settings!!
wlan.ifconfig(config=( '192.168.178.107' , '255.255.255.0' , '192.168.178.1' , '8.8.8.
8' ))
if not wlan.isconnected():
# change the line below to match your network ssid, security and password
wlan.connect( 'mywifi' , auth=(WLAN.WPA2, 'mywifikey' ), timeout= 5000 )
while not wlan.isconnected():
machine.idle() # save power while waiting
Notice how we check for the reset cause and the connection status, this is crucial in
order to be able to soft reset the LoPy during a telnet session without breaking the
connection.
Multiple Networks using a Static IP Address
The following script holds a list with nets and an optional list of
wlan_config
to set a fixed IP
