I tried hooking a friend's Phantom 2 Vision up to my computer. It took 3 computers to find one it worked with. I installed the latest drivers and application from DJI each time. So I get it connected. I get a screen showing the versions of the various firmwares. I press "Update All". If I press that it says all are up to date. If I press the Basic, Advanced, tools, etc buttons, it says "Main Controller firmware mismatch. Please upgrade your firmware!" If I press the "Phantom' button at the top, it gives a long winded spiel about not doing so unless you are an experienced pilot. I backed out of that until I learn more. I had an FC40, so I am familiar with the usual setup. I mainly wanted to activate the IOC, set the limits and program the right switch for RTH. So what is going on? I'm lost. Thanks.
