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
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).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?
