ans =
0000  fixed leader
0080  variable leader
0100  velocity profile data
0200  correlation profile data
0300  echo intensity
0400  PG
1003  garbage
3000  binary fixed attitude
30E0  binary var. att with BT off;
30E8  binary var. att with BT on;
2000  navigation

0500 status  (useless)


If there are two ping types:
0001 fixed leader
0081     etc
0101
0201
0301
0401

The header is the only type that is not duplicated.


mode 1 BB; mode 10 NB
   If only one, this is it;
   if two ping types, then 0100 will always be BB, 0101 will
   be NB, etc.
