3.2.10 Telemetry Info 

 

 

When a compatible GPS, voltage sensor, or OSD are connected to the DragonLink 
receiver and the pin assignments are correctly configured, or when MavLink Decode 
is used to capture telemetry from a valid MavLink stream, the incoming telemetry 
data will be visible on this tab for diagnostic purposes.
