# Mabasej_Team
We are working on system, that will help tourists in cities to get information about city more easily.

# App
Is made in android studio and supports android devices (Android 6<)

# Server
Wikispot is in testing stages, but it is possible to install it using our [.img file](https://github.com/Tucan444/Mabasej_Team/releases/tag/V1.0) based on DietPi or custom script.

## image install
login credentials
> login: dietpi

> password: WikiSpot


requirements:
1. [WikiSpot image file](https://github.com/Tucan444/Mabasej_Team/releases/tag/V1.0)
2. MicroSd card (recommended: >=16GB, :exclamation: ALL DATA STORED ON SD CARD WILL BE FORMATED :exclamation:)
3. [BalenaEtcher](https://www.balena.io/etcher/) (or another sd card flasher) *link:*  https://www.balena.io/etcher/
4. SD card reader


Install:
1. Download all required files (wikispot.img and balenaetcher) and install BalenaEtcher
2. Insert SD card into computer/reader, open BalenaEtcher -> chose Flash from file -> chose downloaded wikispot.img -> Select your sd in *Select target* -> Flash!
3. :exclamation: WINDOWS will show unformated drive. Cancel it. It is because of uncompatible format for windows :exclamation:
4. After flashing open partition *boot* (should apear as USB), find file *dietpi.txt* and open it in text editor.
   - Accept license by changing `AUTO_SETUP_ACCEPT_LICENSE=0` to `AUTO_SETUP_ACCEPT_LICENSE=1`
   - Change name of WikiSpot `AUTO_SETUP_NET_HOSTNAME=WikiSpot-CHANGE_ME` by changing only *CHANGE_ME* or leave *CHANGE_ME* for random number name *WikiSpot-54346
   - You can set static ip address by changing `AUTO_SETUP_NET_USESTATIC=0` to `AUTO_SETUP_NET_USESTATIC=1` And entering your setting into required lines.
   - If you want to use computer vision plugin with rpi camera set `ENABLE_COMPUTER_VISION_PLUGIN=0` to `ENABLE_COMPUTER_VISION_PLUGIN=1` (*recommended only on RPI4)
   - If you want to use RPI as access point to WikiSpot change `#AUTO_SETUP_INSTALL_SOFTWARE_ID=60` to `AUTO_SETUP_INSTALL_SOFTWARE_ID=60`
   - *wifi setup in testing*
5. :grey_exclamation:For advanced users:grey_exclamation: You can now change contens of WikiSpot server in `/boot/WikiSpot`according to an example in server filesystem
6. Eject sd card from computer, insert it in Raspberry Pi and power it on. :bangbang:Raspberry Pi needs to be connected to intenet via Ethernet (*wifi coming soon*) othervise the setup will crash.
7. The setup will take approximately 25-40 min (RPI 4b (2gb) and 70 mb download speed)
8. Done you can start using WikiSpot and edit contents of WikiSpot with our app (*coming soon*)


## Script install
*coming soon*


## Manual install

      "format": ".jpg",                                              # Format of the file

    }
  ]
}
```

To manualy add new file to server (on setup or via ssh) add file to `server_directory/files`
and add record for file into `files` list in `filesystem.json`. :exclamation:do not forget "," after last record:exclamation:

```

    {
      "name": "new_file_name",
      "format": ".txt",
      "description": "This is how you add new file"
    }
```


### settings.json

```
{
  "time_to_heartbeat": 20,                # Time to ping of another online servers in seconds
  "time_to_heartbeat_offline": 25,        # Time to ping of another offline servers in seconds
  "save_table": true,                     # Save connected servers to reconnect after restart

    "save_message": false,                # Save messages (new server, etc. not messages from  clients) into log.txt

    "ID": [],
    "IP": [],
    "location": [],
    "file_system": [],
    "last_heartbeat": []
  }
}
```

If you want to manually add server on first setup or via ssh fill heartbeat table like this.

```
"heartbeat_table": {                    # Saved servers
    "ID": [1],                          # ID of server as integer (number)
    "IP": ["192.168.1.2"],              # IP of server as string
    "location": [""],                   # Empty string as placeholder. location will be downloaded after first connection
    "file_system": [""],                # Empty string as placeholder. filesystem will be downloaded after first connection
    "last_heartbeat": [10]              # After how many seconds will server try to connect for the first time
  }
```

:bangbang:If the server will be offline for long time (heartbeat + offline heartbeat) it will be removed from heartbeat table. If the save function is disabled server will trying to connect after restart:bangbang:
