MissionPlanner Connection issues

[jtripp (Jett Tripp)]

I have some problems getting my MissionPlanner to connect to my RaspberryPi based quadcopter. I can’t seem to get it to connect using my telemetry radio, or through usb cable. I am new to this and I am not sure what could be wrong.

Image and ArduPilot version: Buster - ArduCopter3.6

  When I try to connect mission planner to my quadcopter it can't make a connection. As far as I am aware it should be able to detect that it is plugged in via usb and connect through that. I also have a telemetry radio pair that won't sync up (lights never turn solid green) and so it won't connect over that either.

Step by step actions:
When following along with the documentation for MissionPlanner I have installed it and all of the drivers it automatically pulls up in installation.
Then when I open mission planner up and try to select the connection method it pulls up no com ports
When auto is selected and then I go to initial setup → install firmware → arducopter 4.0.0 and answer the pop-ups it simply errors out saying port auto does not exist.

If using any additional hardware please provide exact make and model:

Hi @jtripp,

It’s not possible to start Ardupilot and establish a connection with MissionPlanner until all the tests are passed.

Based on your screenshot, you have an issue with a barometer test. Please, make sure that the barometer is covered with a foam.

Once the barometer test is passed, please start the ArduCopter using emlidtool.

As far as I am aware it should be able to detect that it is plugged in via usb and connect through that.

Please note, Raspberry Pi is a PC, so you can’t connect it to another PC via USB cable. You can use UDP or telemetry to establish a connection with MissionPlanner.
