There are two WiFi -interfaces, one for the station (when the ESP8266 connects to a router) and one -for the access point (for other devices to connect to the ESP8266). Create -instances of these objects using:: - - >>> import network - >>> sta_if = network.WLAN(network.STA_IF) - >>> ap_if = network.WLAN(network.AP_IF) - -You can check if the interfaces are active by:: - - >>> sta_if.active() - False - >>> ap_if.active() - True - -You can also check the network settings of the interface by:: - - >>> ap_if.ifconfig() - ('192.168.4.1', '255.255.255.0', '192.168.4.1', '8.8.8.8') - -The returned values are: IP address, netmask, gateway, DNS. - -Configuration of the WiFi -------------------------- - -Upon a fresh install the ESP8266 is configured in access point mode, so the -AP_IF interface is active and the STA_IF interface is inactive. You can -configure the module to connect to your own network using the STA_IF interface. - -First activate the station interface:: - - >>> sta_if.active(True) - -Then connect to your WiFi network:: - - >>> sta_if.connect('<your ESSID>', '<your password>') - -To check if the connection is established use:: - - >>> sta_if.isconnected() - -Once established you can check the IP address:: - - >>> sta_if.ifconfig() - ('192.168.0.2', '255.255.255.0', '192.168.0.1', '8.8.8.8') - -You can then disable the access-point interface if you no longer need it:: - - >>> ap_if.active(False) - -Here is a function you can run (or put in your boot.py file) to automatically -connect to your WiFi network:: - - def do_connect(): - import network - sta_if = network.WLAN(network.STA_IF) - if not sta_if.isconnected(): - print('connecting to network...') - sta_if.active(True) - sta_if.connect('<essid>', '<password>') - while not sta_if.isconnected(): - pass - print('network config:', sta_if.ifconfig()) - -Sockets -------- - -Once the WiFi is set up the way to access the network is by using sockets. -A socket represents an endpoint on a network device, and when two sockets are -connected together communication can proceed. -Internet protocols are built on top of sockets, such as email (SMTP), the web -(HTTP), telnet, ssh, among many others. Each of these protocols is assigned -a specific port, which is just an integer. Given an IP address and a port -number you can connect to a remote device and start talking with it. - -The next part of the tutorial discusses how to use sockets to do some common -and useful network tasks. |
