WLAN - Wireless Local Area Network

2024-01-17

This class WLAN is primarily used for controlling the Wi-Fi network card.

Supported module model: FCM360W

Example:

# This example demonstrates the functionality of connecting the Wi-Fi network card to a hotspot and performing network communication.
import network
import utime
nic = network.WLAN(network.STA_MODE)
while nic.status("station_if") != 1011:
    print("Waiting for connection...")
    nic.connect(ssid="your_ssid", password="your_password")
    utime.sleep(1)
print(nic.ifconfig())

# Now use socket as usual
import usocket
addr = usocket.getaddrinfo("python.quectel.com", 80)[0][-1]
s = usocket.socket()
s.connect(addr)
s.send(b"GET / HTTP/1.1\r\nHost: python.quectel.com\r\n\r\n")
data = s.recv(1000)
print(data)
s.close()

Constructor

`network.WLAN`

class network.WLAN(mode)

Initialize WLAN network card and return a WLAN object.

Parameter:

mode - Wireless network card operating mode, int type.
- network.NONE_MODE : 0 - Idle mode.
- network.AP_MODE : 1 - AP (Access Point) mode, supports only wireless client connections.
- network.STA_MODE : 2 - Station mode, connects to a wireless network, such as a router or mobile hotspot.
- network.AP_STA_MODE : 3 - AP+Station mode, supports both wireless client connections and connection to a wireless network.

Note:

Only one WLAN network card object can be created. Attempting to create more will raise an exception: ERR_WLAN_NETIF_IS_BUSY.

The WLAN network card has a total of four working modes as mentioned above. These four modes are actually operations on two network interfaces: the softap interface and the station interface. When the mode is AP_STA_MODE, both softap and station interfaces coexist. Therefore, when calling some interface-specific functions, the interface parameter needs to be specified to indicate the intended interface, or else it won't be clear which interface you are targeting.

Example:

# Create Station mode and connect to a specified AP
import network
nic = network.WLAN(network.STA_MODE)
nic.connect(ssid='your-ssid', password='your-password')
nic.status("station_if")
