Detecting a device's Hotspot



  • Re: wipy as a wifi device sensor
    Can the Sipy or Wipy detect a cellphone when its HotSpot is turned on? When I use WLAN.scan(), it doesn't appear in the list.



  • @sk said in Detecting a device's Hotspot:

    updated my Sipy last wednesday, so it should all be up to date.

    check version by calling

    os.uname()

    I used static at first when configuring with wlan.ifconfig(...) and it only picked up the general wifi from my router, NOT the hotspot.
    I then commented out the ifconfig() but even then it only picked up the general wifi.

    I reinstalled Pymkr and updated my Sipy last wednesday, so it should all be up to date.



  • @sk
    Did you use a static IP or DHCP when you try?
    And what is your firmware version?
    Current is 1.6.3



  • @livius No it can't connect to the hotspot, even if i write the SSID and key.



  • @sk

    import machine
    from network import WLAN
    
    # configure the WLAN subsystem in station mode (the default is AP)
    wlan = WLAN(mode=WLAN.STA)
    # go for fixed IP settings (IP, Subnet, Gateway, DNS)
    wlan.ifconfig(config=('192.168.0.107', '255.255.255.0', '192.168.0.1', '192.168.0.1'))
    wlan.scan()     # scan for available networks
    wlan.connect(ssid='mynetwork', auth=(WLAN.WPA2, 'my_network_key'))
    while not wlan.isconnected():
        pass
    print(wlan.ifconfig())
    


  • @livius How do I do that? My current program is like this:

    import machine
    from network import WLAN
    import pycom
    import time
    
    #WLAN test
    #Doc = https://goo.gl/hHOcbV
    
    #configure the WLAN subsystem in station mode (the default is AP)
    wlan = WLAN(mode=WLAN.STA)      #Setup WLAN as a STAtion
    
    while (True):
    # scan for available networks, returns a tuple of scanned networks
        tup = wlan.scan()     
        for i in range(len(tup)):       #For all scanned networks
            for j in range (4):
                print(tup[i:j])     #Print networks ssid, bssid, sec, channel, rssi
        time.sleep_ms(2000)
        print("RESCAN")

    detect

    what if you manually write ssid of hotspot wfif?
    can you connect? If yes than it is strange that you do not see it on the list..
