please try the latest planner
Thank you michael all connecting ok on the latest mp.
this is happening to me as well, if i restore back to version 1.1.50 it works fine any version after that i cannot connect.
Is this via usb?
what apm version
if xbee what usb board are you using?
also try disabeling "reset apm on connect" in the planner options
I am using APM2.0 purple board, MP 1.1.55, 2.4ghz Xbees in DM mode, one on APM2 in the router mode, the other 2 in end device mode at 38kb. One end device connected to loptop on com 4 in MP 1.1.55 at 38k and it works great ! The other Xbee in end device mode connected to my er9x TX displaying MavLink data at 38kb. Works great.
The only problem I was having was at the 57kb rate. Just can't get it to work. 38kb does work great.
Change serial3_BAUD in MP preferences to 38k and all other coms to 38kb and see if that fixes it.
Same here, I'm on xp , using APM1.4, via usb
no problems with 1.1.50 (had to get back to this version, tried first with 1.1.55,1.1.54,1.1.53,1.1.52 in that order)
So this morning, i tried with 1.1.55, i could load/update apm with 2.5.0 anytime, but could not do anything else (like the setup, or editing Pid's ; Always time out .. always the ""no heart beat packet received")
.. my 2cts for what it can help , thanks Michael for the really good work anyways !
Please try again with 1.1.56, which is specifically updated to address the issue a small minority of users are having with DTR .
Thank you Chris
not really blocking but good to know the bug is spotted and aimed at and apparently solved; What could be the bug so specific to xp?
I'll report as soon as i can, but unfortunately not quite tomorrow, so hope someone else will confirm the bug is gone long before that :)
no bug here on usb or 38kb xbee
btw I am running windows 8 consumer review !
How were you able to install APM Planner to Windows 8?
When I try it tells me I need Framework 3.5.
I've updated to latest firmware (with MP) and this version of mission planner and am still having this issue
try enableing or disableing the reset apm on connect in configuration > planner
