00:00:00,900 --> 00:00:07,140
Until now, we focused on the LoRaWAN protocol and we've explained the transmission from the end-device

00:00:07,140 --> 00:00:08,700
to the Application Server.
2

3
00:00:09,090 --> 00:00:14,580
So, now that the data is decrypted on the Application Server, we'll focus on retrieving this data and
3

4
00:00:14,580 --> 00:00:18,870
storing it in our application that we call the IoT Platform.
4

5
00:00:19,170 --> 00:00:23,880
This IoT platform is where the data will be stored and available to the end user.
5

6
00:00:24,150 --> 00:00:30,060
It's a kind of supervision system and it can be, for example, a mobile application or a simple web

00:00:30,060 --> 00:00:30,690
page.
7

8
00:00:31,140 --> 00:00:36,240
The dialogue between the LoRa server and the IoT platform can be done in many different ways.
8

9
00:00:36,540 --> 00:00:42,900
We'll explain the most common situation, which are HTTP on MQTT protocols.
9

10
00:00:43,170 --> 00:00:48,390
For each of these two solutions, we'll make some demonstration to receive data from the end-device.
10

11
00:00:48,420 --> 00:00:50,610
This is what we call the Uplink stream.
11

12
00:00:50,940 --> 00:00:56,230
And of course, we will also work the other way around; from the IoT platform to the end-device. 
12

13
00:00:56,250 --> 00:00:58,530
It's what we call the downlink stream.
13

14
00:00:59,040 --> 00:01:04,110
But before diving into these two protocols, we'll explain clearly what the IoT platform is.
14

15
00:01:04,140 --> 00:01:06,480
And it's what we're going to do in the next video.
