dastu08 / esp32-weather-station

This is a project with the ESP32 chip onboard the ESP32-devkitc and a temperature and pressure sensor BMP180. It uses the ESP-IDF framework.

esp32-weather-station's Issues

Encryption of UDP traffic

• Use AES to encrypt the UDP traffic.

Task

This means the strings with the JSON objects should be encrypted, then sent via UDP and on the receiving side decrypt the message to get back the JSON object.

The key for AES should be exchanged before hand and will be included in the ESP32 at the time of compilation.

The encryption needs to take place during the call of the function pl_udp_send. Currently it is called in al_weather_station.

Suggestion

Add an extra component doing the encryption and then define new functions
in the pl_udp component to encrypt the message before sending it via UDP.

accept json

Accept the incoming UDP message to be formated in json.

Some examples

{"type":"get","quantity":"temperature"}
{"type":"get","quantity":"pressure"}
{"type":"get","quantity":["temperature", "pressure"]}
{"type":"set","name":"heartbeat","value":"on"}
{"type":"set","name":"heartbeat","value":"off"}
{"type":"set","name":"heartbeat_interval","value": 30}}
{"type":"set","name":"measurement_interval","value": 5}}

Use a type to either get a value in return or set a value.

For get the quantity has to be specified that will be returned. This should also include lists like "quantity": [ "temperature", "pressure" ].

For set the name of the variable to set and the value should be given.

All field values should be lowercase and use underscores.

Version numbering

• Add version numbering tags in repo.
• Create releases on github for stable versions.
