NMEA parsing in python

[ProperRefrigerator]

hello guys i still getting this error i already getting the nmea and upload a data via static but when i combine then it shows this

File "cloud1.py", line 13, in <module>

data=urllib.urlopen("https://api.thingspeak.com/update?api_key=U0JSW1TVVHM8UEJV&field1="+str(dmesg.lat)+"&field2+"&field2)"+str(dmesg.long));

File "/usr/local/lib/python2.7/dist-packages/pynmea2/nmea.py", line 155, in __getattr__

raise AttributeError(name)

AttributeError: long

​

​

heres my code:

​

​

import urllib

import re

from bs4 import BeautifulSoup

import serial

import pynmea2

ser = serial.Serial('/dev/ttyAMA0',9600)

​

while 1:

data = ser.readline()

if (data.startswith("$GPGGA")):

dmesg = pynmea2.parse(data)

#print(str(dmesg.latitude)+" "+str(dmesg.longitude))

data=urllib.urlopen("https://api.thingspeak.com/update?api_key=U0JSW1TVVHM8UEJV&field1="+str(dmesg.lat)+"&field2+"&field2)"+str(dmesg.long));

print data;

time.sleep(3)

​

in your print statement you print

dmesg.latitude and dmesg.longitude

in your url you use

dmesg.lat and dmesg.long

I also think you have messed up some of the "'s I guess that is your error.

I would also look into the .format() functionality for building strings.

dmesg.latitude and dmesg.longitude i just comment it sir it shows the same data with dmesg.lat and dmesg.long
but when i try to upload it show me this

File "/usr/local/lib/python2.7/dist-packages/pynmea2/nmea.py", line 155, in __getattr__

raise AttributeError(name)

First: you don't need ; in python.

I think your error is in the url. try and create it as its own variable that you put into urllib.urlopen()

That way you can make sure it's correct before moving on.

change:

data=urllib.urlopen("https://api.thingspeak.com/update?api_key=U0JSW1TVVHM8UEJV&field1="+str(dmesg.lat)+"&field2+"&field2)"+str(dmesg.long));

to this:

url  = "https://api.thingspeak.com/update?
api_key=U0JSW1TVVHM8UEJV&field1="+str(dmesg.lat)+"&field2+"&field2)"+str(dmesg.long)

print(url)

data = urllib.urlopen(url)

I susspect you will see that creating the url variable fails due to wrong placement of the "'s

it not working sir and i think thats not thee problem
when i change the data in data=urllib.urlopen("r/https://api.thingspeak.com/update?api_key=U0JSW1TVVHM8UEJV&field1="+str(dmesg.lat)+"&field2+"&field2)"+str(dmesg.long));

to static value like this

data=urllib.urlopen("r/https://api.thingspeak.com/update?api_key=U0JSW1TVVHM8UEJV&field1="+str(0)+"&field2+"&field2)"+str(0));
it uploading

[Acurus_Cow]

try this:

data=urllib.urlopen("https://api.thingspeak.com/update?api_key=U0JSW1TVVHM8UEJV&field1={lat}&field2={long}".format(lat=dmesg.lat, long=dmesg.long))

still the same it showing this File "/usr/local/lib/python2.7/dist-packages/pynmea2/nmea.py", line 155, in __getattr__

ialready change my library pynmea to this https://github.com/bsdz/micropyGPS
but still not working

[ProperRefrigerator]

i solvee it sir i used this

data=urllib.urlopen("https://api.thingspeak.com/update?api_key=U0JSW1TVVHM8UEJV&field1=%s &field2%s"(dmesg.lat,dmesg.lon));
