- Decide which drone autopilot you are going to fly with. APM or PX4?
- When you update your autopilot firmware, make sure you choose correct autopilot.
Those FlytConsole widgets that do not work with APM will show you this message. Instead use APMPlanner or Mission Planner for APM or QgroundControl for PX4, for frame, calibration etc.
It seems you had installed PX4 while updating your firmware, which is supported by FlytConsole. That's why you got the widgets working.
Also, how are you connected to Pixhawk? via Uart or USB? For APM, yesterday I came to know that they recommend to not use USB of Pixhawk for connecting to Companion Computer. I hope you are using UART of Pixhawk.
No, ofcourse FlytOS would work with any Companion Computer of your choice, and is not restricted to FlytPOD. Please take a look at this and post your log here.
Offboard is same as GUIDED mode. Just configure FLTMODE parameter in mission planner accordingly.
