I am facing a problem with APM2.5 while connecting to Mission Planner latest version, my APM2.5 has arducopter hex v3.1.2 firmware in it. Previously I did not face this issue, but after updating my MP to the latest version I am getting this problem, here attached what my MP is showing while connecting... Please suggest me a solution ASAP...apm_MP_Issue.png
the comport is in use by some other app.
Have you figured this out?
I have tested with the latest beta build 1.1.5256.22569 and it works fine. it seams like a non mission planner issue. make sure noe other programs are using the serial port. a restart might help if there is a lock on the serial port somehow.
