Not getting Sensor Readings in Pysense with FiPy Module

[Archana Kadam]

We are trying to connect to the station and access media using the procedure given the documentation. We are unable to connect to the accurate station and access point to specified IP address and ssid.
Could you please help to this problem

Thank You

@archana-kadam
Do you mean Wifi?
How your trying looks like? Any sample code. And if this is Wifi - what are your security settings on your router - WPA2 or something different?

[Archana Kadam]

@livius
Yes, We are trying to connect WiFi and our router is setup at WPA2 configuration.We tried with sample code provided in the pycom documentation.
We want fipy board to be worked as both station and access point

Thank You

@archana-kadam
Did you fallowed both samples?
https://docs.pycom.io/chapter/tutorials/all/wlan.html
https://docs.pycom.io/chapter/firmwareapi/pycom/network/wlan.html

better show the code and then we can help more -of course without passwords ;-)

[Archana Kadam]

@livius
https://docs.pycom.io/chapter/firmwareapi/pycom/network/wlan.html
we tried with this sample examples.

1. what you get when you do

nets = wlan.scan()
print(nets)

2. is there your net ssid? and is there info about WPA2?
3. do you use static IP?
   this line is for static ip settings - but you must change it to follow your router settings

wlan.ifconfig(config=('192.168.0.107', '255.255.255.0', '192.168.0.1', '192.168.0.1'))

@livius
By using
nets = wlan.scan()
print(nets)
we are getting details of connected WiFI.
Yes we have our net ssid and is configured to WPA2. Yes we were using this wlan.ifconfig(config=('192.168.0.107', '255.255.255.0', '192.168.0.1', '192.168.0.1'))
to configuration. How we can know that our WIFI is connected or disconnected

[livius]

@archana-kadam
you have wlan.isconnected() for that look here:
https://docs.pycom.io/chapter/tutorials/all/wlan.html#connecting-to-a-router

and are you sure that your router have same ip settings? 192.168.0.1?

[Archana Kadam]

@livius

from network import WLAN
wlan = WLAN(mode=WLAN.STA)
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

Using above code we are getting the details of connected wifi. And we have different ip address. Here is the screenshot of our output please go through the image and update.
Thank You

@archana-kadam
than you are connected to wifi - what more do you need?

[Archana Kadam]

@livius
How we can know that is connected to Wifi?
How we can connect to both station as well as access point?

[Archana Kadam]

@livius
Please explain the procedure of connecting fipy to server and how to send data of fipy to server

How we can know that is connected to Wifi?

wlan.isconnected()
but to be really sure - only sending by socket tell this for sure

How we can connect to both station as well as access point?

change mode from WLAN.STA in WLAN.STA_AP

Please explain the procedure of connecting fipy to server and how to send data of fipy to server

simply create socket and send data throught it

e.g. from memory not tested but something like this should work

import socket
s = socket.socket()
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(socket.getaddrinfo('your server ip', your_server_port)[0][-1])
s.send(your_data)

[Archana Kadam]

@livius
Can we send data through pybytes ?
Is a pybytes a server or its just a middleware to send data?

[Archana Kadam]

@livius
From this above code we are getting an error called OSERORR :-01
import socket
s = socket.socket()
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(socket.getaddrinfo('192.168.0.109', 80)[0][-1])
your_data = "Hello"
s.send("your_data")

[livius]

@archana-kadam

From this above code we are getting an error called OSERORR :-01

At which line of code?

[Archana Kadam]

@livius
Line number 6 and 7

[livius]

@archana-kadam said in Not getting Sensor Readings in Pysense with FiPy Module:

Line number 6 and 7

I do not have your source code ;-)
what this lines contain? and why on 6 and 7 - error should be raised only once

[Archana Kadam]

@livius
import socket

host = '127.0.0.1'
port = 80 # The same port as used by the server
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host, port))
s.send('Hello, world')
data = s.recv(1024)
s.close()
print('Received', repr(data))
Here is code to connect to server,but we are enable to connect

[Archana Kadam]

@livius
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())
I tried with code also, but its continuously running but there no output.
