I have been having a few issues with 2.8 and have seen in mission planner that there is an option to install an old firmware. When I click this menu all it gives are long sets of charachters. I was wondering if anyone knew what code in the menu corresponds to Arducopter quad 2.7?
Does anyone know how to do this? I'd like to install 2.8.1. Mission Planner wants me to pick 2.9.1. If I select from the drop down list for older firmware I too get long lists of hex characters. Which choice represents 2.8.1?
It turns out you can just start at the top of the list and choose one. The screen will update with the firmware numbers after you make a selection and before you choose to load it. It works well.
