 # Plugin Architecture
 
-Although the MAVLink spec defines a standard communication protocol to communicate with a vehicle. There are many aspects of that spec that are up for interpretation by the firmware developers. Because of this there are many cases where communication with a vehicle running one firmware is be slightly different than communication with a vehicle running a different firmware in order to accomplish the same task. Also each firmware may implement a different subset of the MAVLink command set.

Also each firmware may implement a different subset of the MAVLink command set.
 
 Another major issue is that the MAVLink spec does not cover vehicle configuration or a common parameter set. Due to this all code which relates to vehicle setup ends up being firmware specific. Also any code which must refer to a specific parameter is also firmware specific.
