## Installation API Python de Huawei

~~~

pkg_add py3-pip  

ln -sf /usr/local/bin/pip3.6 /usr/local/bin/pip 

pip install huawei-lte-api

# API: /usr/local/lib/python3.6/site-packages/huawei_lte_api/api

# For more API calls just look on code in the huawei_lte_api/api folder, there is no separate DOC yet

~~~ 

## Consulter l'API Huawei ( en Python )

~~~ python

from huawei_lte_api.Client import Client

from huawei_lte_api.AuthorizedConnection import AuthorizedConnection

from huawei_lte_api.Connection import Connection

connection = AuthorizedConnection('http://admin:MOTDEPASSE@192.168.8.1/')

# connection = AuthorizedConnection('http://admin:MY_SUPER_TRUPER_PASSWORD@192.168.8.1/', login_on_demand=True)

# connection = Connection('http://192.168.8.1/')

client = Client(connection)  # This just simplifies access to separate API groups, you can use device = Device(connection) if you want

print(client.device.signal())  # Can be accessed without authorization
