"Because there is/was lot of new ones without blobs joints on PCB. Yes, best is V2 with switching and blobs but in time of original post was problem to find them and some versions had switching but not easy way to interconnect. "

"Well, thanks for letting us know. I really expected that it will be something with power because it went away when I take off bluetooth module from copter. I can imagine that this will simply change way how is voltage getting off.

Can you give us…"

"So I put freezer bags on hawk and waiting.

Do somebody know what press_temp value means ? C divided by 100 ?

I just disabled GPS precheck (in basement doesn't work even Neo8) and now getting Thr below falsafe so I suppose that arming precheck are…"

"I definitely agree. It is good think that FW is improved and reporting more potential problematic during start-up. Security first, no question, better than see fly away or crash.

But I am trying to get on core - what is real problem. Lot of…"

Amper (DevFor8.com) commented on William Davidson's blog post Market Survey/ What is needed?
"From my perspective - please, please, do nothing. Keep with army stuff and keep away from end customer market. We have enough "nice" video captures from Phantoms on YT and all of them went to more and more regulations.

Doesn't matter if you live in…"

"Fast temperature changes is something what sensors don't like - for example baro can show you big alt changes (even with correct code for temp compensation). This is reason why I am trying to power board and then let it for a while to heat itself to…"

Is it possible that bluetooth module attached to Serial1 makes…"

Amper (DevFor8.com) replied to Randy's discussion ArduCopter-3.2 beta testing
"I am using $9 bluetooth module connected to one copter. Sure, range is limited but still, 5m without cables is much better for configuration than cable :-)

And for Pixhawk - you need only cheap module from china and cable with DF13 to connect it…"
