Initialization and Connection

Inkplate2 uses ESP32 to handle WiFi connections. This page demonstrates how to connect your Inkplate board to an existing WiFi network.

WiFi Connection Example

from inkplate2 import Inkplate
import network
import time

# WiFi credentials
SSID = "YOUR_SSID_HERE"
PASSWORD = "YOUR_PASSWORD_HERE"

inkplate = Inkplate()

inkplate.begin()

# Connect to a WiFi network using given SSID and PASSWORD.
sta_if = network.WLAN(network.STA_IF)

connected = False

if not sta_if.isconnected():
    inkplate.println("Connecting to network...")
    sta_if.active(True)
    try:
        sta_if.connect(SSID, PASSWORD)
    except Exception as e:
        print(f"Wi-Fi connect error: {e}\n")
        print("Check your credentials!")
    else:
        timeout = 30  # seconds
        start = time.ticks_ms()

        while not sta_if.isconnected():
            if time.ticks_diff(time.ticks_ms(), start) > timeout * 1000:
                print("Failed to connect within timeout")
                break
            time.sleep(0.5)
        else:
            connected = True
else:
    connected = True

if connected:
    inkplate.print(f"CONNECTED: \n{sta_if.ifconfig()}")
    
inkplate.display()

network.WLAN()

Create a WLAN network interface object and connect to WiFi access point

Function parameters:

Type	Name	Description
int	interface_id	Set to network.STA_IF for connecting to access point, or network.STA_AP to allow other WiFi clients to connect

WLAN.active()

Create a WLAN network interface object and connect to WiFi access point

Returns value: Returns current state if no argument is provided

Function parameters:

Type	Name	Description
bool	is_active	Activate/Deactivate network interface if arguments is passed

WLAN.connect()

Connect to the specified wireless network, using the specified key (only works in STA interface)

Function parameters:

Type	Name	Description
string	ssid	Network SSID
string	key	Network password

WLAN.isconnected()

Check the connection status

Returns type: Bool

Returns value: Returns True if connected to a WiFi access point and has a valid IP address. In AP mode returns True when a station is connected, otherwise False

WLAN.ifconfig()

Get/Set network interface parameters: IP address, subnet mask, gateway and DNS server

Returns type: Tuple

Returns value: When called with no arguments, returns a 4-tuple with the above information

Function parameters:

Type	Name	Description
Tuple	(ip, subnet, gateway, dns)	Network parameters
