list wifi

for network in wifi.radio.start_scanning_networks():
    print(f"{network.ssid} [Ch:{network.channel}] RSSI: {network.rssi}")

connect to wifi

wifi.radio.connect(ssid, password)

print wifi info

if wifi.radio.connected:
    print("wifi SSID info = ",wifi.radio.ap_info.ssid)
    print('transmit power', wifi.radio.tx_power)
    print(f"My MAC address: {[hex(i) for i in wifi.radio.mac_address]}")
    print("radio enabled", wifi.radio.enabled)
    print("host name", wifi.radio.hostname)

fetch HTTP request

# Initalize Wifi, Socket Pool, Request Session
pool = adafruit_connection_manager.get_radio_socketpool(wifi.radio)
ssl_context = adafruit_connection_manager.get_radio_ssl_context(wifi.radio)
requests = adafruit_requests.Session(pool, ssl_context)

with requests.get("http://webpage.site") as response:
    print(response.text)

CircuitPython Tricks

get the network time

# specific to the MatrixPortal M4
pool = adafruit_connection_manager.get_radio_socketpool(matrix.network._wifi.esp)
# most modern boards
pool = adafruit_connection_manager.get_radio_socketpool(wifi.radio),

# get the time
ntp = adafruit_ntp.NTP(socketpool=pool)

# print the time
print(ntp.datetime)

For the MagTag use magtag.get_local_time(), but you’ll need to setup the Adafruit IO credentials in settings.toml.

magtag.get_local_time() # sync with the network time
now = time.localtime()
