Greetings,
finnaly got it working :D Problem was with descrambler. Now it gives results
as follows:
Service: 'ok'
Duration: '0000'
Source_MAC_Adress: '232323232323'
Destination_MAC_Adress: 'FFFFFFFFFFFF'
Protocol_version: 'Supported'
Type: 'Data'
Subtype: 'Data'
To_DS: 'False'
From_DS: 'False'
More_fragments: 'No'
Power_menagement: 'Active'
More_data: 'No'
Protected: 'No'
Order: 'Random'
Great
But I still dunno how to estimate initial descrambler state (checked all and
found correct one this time).
Descrambler graph sould be the same as the scrambler from you paper right?
On the receiving side, take the first 7 bits, put them in the scrambler
register, and use the very same algorithm on as on TX side. (Since the
output of the scrambler is fed back the first seven bits are also the
internal state of the scrambler).
