This API is built on Flask and connects to a mongoDB storage attached to this app. The purpose is receiving HTML POST messages from Actility every time a LoRaWAN packet has been received. Spaghetti API stores all the relevant data and prepares them to be fetched with other apps connecting with REST API.

##Description of the API
###Data input
The app route /sc_lpn handles the data input from Actility Thingpark with HTTP POST in the format given by Actility.

App route /gateway can handle the input of new gateways to be stored in the database, when used with HTTP POST.
Arguments:
id: gateway EUI as a string
lat: latitude of the gateway
lon: longitude of the gateway

App route /import can import from a backup point-by-point. All the point information has to be given as arguments. The function is not tested yet, for this purpose, a script needs to be written that transforms the .json backup into a series of POST requests.

##Data output

App route /gateway with HTTP GET returns all the gateways within a certain radius around the center point. Arguments:
lat: latitude of the center point
lon: longitude of the center point
radius: radius in km, output will contain all gtws within this radius.

App route /json returns a .json file for download, containing the current point database. Might take some CPU...

App route /query is filtering the database for certain criteria and only returns the points of interest.
Arguments:
delpoint+timestamp deletes a specific point
track: returns only a specific track number. Default: 20
start: String with start time. Default: 1 year ago
end: String with end time. Default: now
hdop: maximum GPS HDOP. Default: 500
sf: Spreading factor. Default: 7
txpow: Transmission power. Default: 0
device: Filter for transmissions of a specific device EUI only. Default: All devices
