from uart1.h in NaviCtrl code (please take a look at SVN for latest version of header files)
Navigation Data
The MikroKopter will send these data after getting the abbo command 'O' with interval and max bytes per second.
Interval
This value [10ms] is used when starting the abbo.
10 => send the data every 100ms
Max Bytes per second
This value [bytes per second] is used when starting the abbo.
It is used to keep the used bandwith to a specified (max) level according to the maximum data throughput of the communication interface.
A useful value could be 1024 for a good wireless transmission and 200 for a slow transmission like GSM-Modems etc.
Index
The MK will send differnt data sets automatically.
Data that did not change will be sent more seldom than sets that with changed data content.
The different data sets can be identified by the index.
