In all the years that the Nike+ Ipod deal been out there, has anyone published an algorithm or method to decode the Hex data coming out of the Reciever? I'm talking about this data:
FF 55 1E 09 0D 0D 01 70 C5 07 30 A5 FD AE FA C4 BF 32 0C 52 86 08 AF C9 EA 1C 56 31 CA B8 02 33 32 79
FF 55 1E 09 0D 0D 01 70 C5 07 30 A6 45 59 1F 91 DC 8E C4 FB 66 37 DB 010 9E 75 69 6F 99 08 C4 0A 95 BE
FF 55 1E 09 0D 0D 01 70 C5 07 30 A7 1C 94 06 1A 84 A8 010 9A 22 E8 F8 8B F9 67 44 0E 6B AB BB E0 C2 53
The only information I have found is more than two years old and very limited.
FF 55 : Apple Accessory Protocol header
1E : length of packet data (from mode through data before checksum)
09 : mode for Nike+
0D 0D : command
01 : unknown (start of parameter)
70 C5 07 30 : my transmitter’s ID
A5 : appears to be a counter, always starts with A, counts from 0-F
next 21 bytes : unknown
I know it's been done because there are websites like johnnyjogger.com that give you the distance and time data. Well Johnny is not responding to emails, and Google is not relinquishing anyone secrets either.
Have any of you guru's worked on this?
