## 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:Rosedor123@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
