"I received my APM 2560 in the mail today, and promptly assembled it. Looks like my problem was localized to my old APM, so it must have been a hardware issue. Either I screwed something up with the assembly or it was dead on arrival. My AC boots…"

"Doug,   Sorry about the late reply, had to work late last night and didn't get a chance to work on the copter.   I'm using 2.0.33beta for the firmware and for the APM Mission planner its 1.0.26 build 1.04.4203.31490.   What…"

"Glad to hear that worked for you, Tim!  I'm curious what version numbers you have for Mission Planner and AC2.  I just updated this morning with MP 1.0.24 (build 1.0.4201.29409) and AC 2.0.33 Beta.  However, MAVlink still times…"

"Thanks Paul!  I ran various component tests, all with passing results.  Or at least I got sane data out of them.   ArduPilot Mega BMP085 library test Pressure:0 Temperature:0.00 Altitude:44330.00 Pressure:101000 Temperature:26.50…"

"Guys,   I just tried the latest AC2 code via the latest APM mission planner and now the mavlink connects OK. Until I tried this combination of software firmware, I was getting the standard timout commands in the console. Now, the artificial…"

"Doug, Great minds think alike eh? I was PMing you when you posted here.  You should load the Arduino IDE if you haven't already Its pretty straighforward. Next download AC2 latest version to disk manually so you know where it is, then run…"

"In general MAVLink connect issues mean that your IMU isn't booting up, which is usually due to a hardware issue. If you got to the Mission Planner Help tab and click the box to enable the console, and then close and restart, you can see the…"
