Detecting a device's Hotspot

[sk]

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.

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..

@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")

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

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

@livius
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.
