Pages: 1 2 3

I'm trying to use modemcmd
I can only install it using pip install
when I ty to use pip3 install modemcmd
I get :

Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Collecting modemcmd
Could not install packages due to an EnvironmentError: 404 Client Error: Not Found for url: https://pypi.org/simple/modemcmd/

so what will be a good solution for this problem?

Thanks,

Looks like you don't have the library installed. Did you also try to install it?

It's like this.

pip3 install modem-cmd

I'm getting this error now

python3 GetAllData_Working_backup.py
Traceback (most recent call last):
  File "GetAllData_Working_backup.py", line 5, in <module>
    from modemcmd import modemcmd
  File "/home/pi/.local/lib/python3.7/site-packages/modemcmd/__init__.py", line 2, in <module>
    from serial import Serial
ImportError: cannot import name 'Serial' from 'serial' (/home/pi/.local/lib/python3.7/site-packages/serial/__init__.py)

this is the full code , I have only import the wanted packages

import asyncio
import websockets

import time
import datetime
import serial
import pynmea2
from modemcmd import modemcmd
from modemcmd import ModemcmdException
from modemcmd import ModemcmdTimeoutException

from gpiozero import CPUTemperature


ser = serial.Serial('/dev/ttyUSB1',9600,timeout = 0.5)

ModemInfo = '/dev/ttyUSB2'

It now read from wrong package,it shall read from pyserial and then sub-folder serial.
Rename or delete python3.7/site-packages/serial/ folder and try again.

You could of course use virtual environment,it's build into Python and then will avoid conflict like this.
Example.

tom@tom:~$ python -m venv modem_env
tom@tom:~$ cd modem_env/
tom@tom:~/modem_env$ source bin/activate

** it's seem like a easier option

Thanks,

Linux – Rename, Move, Copy and Delete Files (mv, cp,rm)

I just want to be sure
I will remove this folder using

rm python3.7/site-packages/serial/

then install using

pip3 install pyserial

is this correct?

rm -r /home/pi/.local/lib/python3.7/site-packages/serial/

pip3 install modem-cmd dos install pyserial.
Look at my demo before where i install it.

Ok
now I don't get this error

but when I try to run the code I get that somehting is wrong with the modem-cmd package

import time
import datetime
import serial
import pynmea2
from modemcmd import modemcmd
from modemcmd import ModemcmdException
from modemcmd import ModemcmdTimeoutException


ser = serial.Serial('/dev/ttyUSB1',9600,timeout = 0.5)
ModemInfo = '/dev/ttyUSB2'

try:
    result = modemcmd('/dev/ttyUSB2', 'AT+CSQ', 2)
except ModemcmdTimeoutException as e:
    print (e)
except ModemcmdException as e:
    print (e)

but I get this error:

Traceback (most recent call last):
