DVB Adapters API

In the Astra interface, you can manage DVB Adapter configurations and control their status using HTTP API methods.

Adapter configuration

{
    "id": "...",
    "name": "...",
    "type": "...",
    "enable": true,
    "adapter": 0,
    "device": 0
}

name - adapter name;
type - adapter type: S, S2, T, T2, ATSC, ISDB-T, C, C/A, C/B, C/C;
enable - true if adapter is enabled;
adapter - number of adapter in the system: /dev/dvb/adapter0
device - number of the device in the adapter: /dev/dvb/adapter0/frontend0
other options depends of the adapter configuration

Obtain Adapter configuration

Request: GET /api/adapter-info/{id}

id - unique adapter identifier

In response will be JSON with adapter configuration

Modify Adapter configuration

Request: POST /control/

{
    "cmd": "set-adapter",
    "id": "...",
    "adapter": {...}
}

id - unique adapter identifier
adapter - adapter configuration

Restart Adapter

Request: POST /control/

{
    "cmd": "restart-adapter",
    "id": "..."
}

id - unique adapter identifier

Remove Adapter

Request: POST /control/

{
    "cmd": "set-adapter",
    "id": "...",
    "adapter": {
        "remove": true
    }
}

    "signal_db": 0,
    "snr": 0,
    "snr_db": 0,
