I have connected APM 2.6 flight controller with raspberry pi 3B through serial port. I have enabled the UART over raspberry pi as well and also have checked whether the UART on the raspberry pi is working fine or not. I have used minicom to check the availability of serial ports on raspberry pi, and it seems that the port on the pi end are working pretty fine.
The problem which i am facing is that, while connecting through UDP to mission planner i can get all the live data from the sensor while the mission planner can't load the parameters and is stuck with the dialog box showing "Getting parameters".
Moreover there is no file in the raspberry pi for the parameters. Some help will be greatly appreciated. Thanks in advance.
