I have just joined DIY Drones and my son and I are doing things the hard way as we are trying to work things out as we go along.
We have mission planner and the APM 2.5 board
When we try and connect we get error messages saying "Cant open serial port"
We are on Windows 7 and have tried the same exercise on 2 PCs now with Windows 7
We have followed all the instructions but we are at a roadblock that seems to be doing its job very well.
I have searched the forum but I cant find anything that has helped us solve the issue.
We have reloaded drivers, ports, MP and so on.
If anyone has some advice we would love to hear from you.
We use our quad for general GoPro stuff on our outdoor activities but we were keen to get a little GPS control.
Our Youtube name is JBBunno if anyone is interested to have a look.
Thanks in advance
