Error in new update in command Hitag

I tested new update and see error.
When i tried write data 00 00 00 22 to page 6 of transponder and used "snoop" command i see log:
ETU     :rssi: who bytes
---------+----+----+-----------
+        0:    :     c0
+   1456:    :     9a  92  96  a4
+   1456:    :     64  80
+     756:    :     00  00  00  44

So password was 4D 49 4B 52, in log it looks like password *2 and data is *2

Re: Error in new update in command Hitag

Use a different angle, distance or antenna. This will solve your problem.

Furthermore, you see that it seems to miss the first bit, which makes the Manchester decoding fail (1 bit shifted). This is indeed the same as if you value is multiplied by 2, but it actually just shifted, because the first bit is missing wink

A better trace should solve the bit-shift problem as well!
