BERadioMessage

The most convenient interface on API level.

Import module:

>>> from beradio.message import BERadioMessage

Construct message with nodeid=999:

>>> message = BERadioMessage(999)

Fill with data:

>>> message.temperature(21.63, 19.25, 10.92, 13.54)
>>> message.humidity(488.0, 572.0)
>>> message.weight(106.77)

Encode the message to wire format:

>>> str(message)
'd1:#i999e1:_2:h11:hli48800ei57200ee1:tli2163ei1925ei1092ei1354ee1:wi10677ee'

Decode back:

>>> print BERadioMessage.json(str(message))         
{
    "data": {
        "hum1": 488.0,
        "hum2": 572.0,
        "temp1": 21.63,
        "temp2": 19.25,
        "temp3": 10.92,
        "temp4": 13.54,
        "wght1": 106.77
    },
    "meta": {
        "gateway": "None",
        "network": "None",
        "node": "999",
        "profile": "h1",
        "protocol": "beradio2",
        "time": ...
    }
}

Construct small messages on purpose

Construct and fill message:

>>> message = BERadioMessage(999)
>>> message.temperature(21.63, 19.25)
>>> message.weight(106.77)

Show what’s up:

>>> str(message)
'd1:#i999e1:_2:h11:tli2163ei1925ee1:wi10677ee'
>>> len(str(message))
44

Decode back:

>>> print BERadioMessage.json(str(message))         
{
    "data": {
        "temp1": 21.63,
        "temp2": 19.25,
        "wght1": 106.77
    },
    "meta": {
        "gateway": "None",
        "network": "None",
        "node": "999",
        "profile": "h1",
        "protocol": "beradio2",
        "time": ...
    }
}

Decode message fragments

Apply list continuation by honoring index offsets encoded after family identifier.

Define message:

>>> message = 'd1:#i2e1:_2:h12:t6li8484ei2121ee1:hli5000ei5500ei7710eee'

Decode message:

>>> print BERadioMessage.json(str(message))         
{
    "data": {
        "hum1": 50.0,
        "hum2": 55.0,
        "hum3": 77.1,
        "temp7": 84.84,
        "temp8": 21.21
    },
    "meta": {
        "gateway": "None",
        "network": "None",
        "node": "2",
        "profile": "h1",
        "protocol": "beradio2",
        "time": ...
    }
}
