WLAN step by step ================= The WLAN is a system feature of the WiPy, therefore it is always enabled (even while in ``machine.SLEEP``), except when deepsleep mode is entered. In order to retrieve the current WLAN instance, do:: >>> from network import WLAN >>> wlan = WLAN() # we call the constructor without params You can check the current mode (which is always ``WLAN.AP`` after power up):: >>> wlan.mode() Connecting to your home router ------------------------------ The WLAN network card always boots in ``WLAN.AP`` mode, so we must first configure it as a station:: from network import WLAN wlan = WLAN(mode=WLAN.STA) Now you can proceed to scan for networks:: nets = wlan.scan() for net in nets: if net.ssid == 'mywifi': print('Network found!') wlan.connect(net.ssid, auth=(net.sec, 'mywifikey'), timeout=5000) while not wlan.isconnected(): machine.idle() # save power while waiting print('WLAN connection succeeded!) break Assigning a static IP address when booting ------------------------------------------ If you want your WiPy to connect to your home router while after boot-up, and with a fixed IP address so that you can access it via telnet or FTP, use the following script:: import machine from network import WLAN wlan = WLAN() # get current object, without changing the mode if machine.reset_cause() != machine.SOFT_RESET: wlan.init(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 .. note:: Notice how we check for the reset cause and the connection status, this is crucial in order to be able to soft reset the WiPy during a telnet session without breaking the connection.
