Documentation for the Advertisement object

[Mark Tyers]

Is there any documentation that explains the data returned in the Advertisement object?

[Barry Byford]

Not sure I understand the question. Could you clarify.

Do you mean this:

https://github.com/TheCellule/python-bleson/blob/master/bleson/core/types.py#L390

More generally, all of the HCI information is documented in the Bluetooth® Core Specification:

https://www.bluetooth.com/specifications/bluetooth-core-specification/

It is rather a large tome so take a look at. If you are looking at advertisement data received then:

7.7.65 LE Meta event on page 2379 is probably a good place to start.

For work I've done elsewhere I think that breaks down as:

# pkt[0] = Packet Type (0x04) Is packet type

# pkt[1] = HCI event type (We only interested in 0x3e?) LE Meta Event

# pkt[2] = Length of packet

# pkt[3] = LE Meta Event sub event (see LE_META_EVENT_LOOKUP)

# pkt[4] = Number of reports in packet

# pkt[5] = Advertisement Report Event Type (see ADV_RPT_TYPE_LOOKUP)

# pkt[6] = Address Type (see ADDRESS_TYPE_LOOKUP)

# pkt[7:13] = Mac address

# pkt[13:] = Advert packet information

# pkt[-1] = Receive Strength Signal Indicator (RSSI)

There is also a Beacon Advertising Cheat Sheet posted by Jos Ryke available at:

HI,

You could access Advertisement.raw_data:  https://github.com/TheCellule/python-bleson/blob/master/bleson/core/types.py#L386

Then pass it to a parser such as:   https://github.com/xorbit/py-decode-beacon/blob/master/decode_beacon.py

A/that iBeacon parser is perhaps something worth adding to Bleson.

All the best

Wayne
