External Pitot Pressure Packet

This packet is no longer supported. The External Air Data packet #68 should be used.
13.9.38

Wind Packet

This packet provides Spatial's current 2D wind velocity. These values are only valid
when external air data is provided to Spatial. This can be either through the External
Pitot Pressure Packet, the External Air Data Packet or when a pitot tube is interfaced to
one of the GPIO pins. When this packet is written to the device, it disables the wind
estimation filter and the wind values provided are used statically.
