IOT

Internet of things with the ESP8266 SoC. All of these have been implemented using Arduino IDE (not very proud of it :)

1. OTA (Over the air) internet via AWS web hosting.

• This firmware(the code) to be updated is hosted over a server, aws in this case.

• Checks for the frimware update every specified unit of time.

• However there is no check for a secure transmission of the data through the server. I'm talking about the security certificates (This has not been implemented).

2. Use cases of MQTT protocol.

• MQTT protocol using AWS

• MQTT protocol using ThingSpeak, however I haven't tried enough to get it right all the time. Loss of data and stuff while transmitting the payload.

3. Serial Commuinication using UDP protocol.

• Server-Client based one to one and one to many using UDP protocol.
