eth_device decorator is used to implement an api to ethernet devices.
|
|
|
When eth_device decorator is used it adds two parameters to any function (ip and port)
|
|
|
|
|
|
#Definition

@eth_device

def enable_rf()

cmd = "xxxxx"
|
|
|
payload = "xxxxxx"
|
|
|
|
|
|
return cmd, payload
|
|
|
|

#How to call this function:

answer = enable_rf(ip, port)
