Here is something confusing to me........ My APM2 will not arm the motors until I push the reset button.
I use a 7.4v batt through a BEC to power the board. All of my esc's are opto isolated. I run a 5800mah 4s batt for the motors. I have powered the board both ways with or without the jumper through the input and output. The only way I can arm the motors is resetting the APM2 while the batteries are plugged in either by pushing the reset button or unplugging and replugging the APM2.
i have same thing .... the APM2 seems not to boot up correct until i press the Reset button.
I just finished calibrating the esc. The motor ran after I calibrated it. Somehow, now I can't arm the APM2. Is there anything I need to do on the Mission Planner before I can use it? I followed the guide and it said something about a FLY mode switch. Where is that on APM2?
Try this.. I am been doing this stuff all day!! :D
1. Take the props off
2. Plug the APM2 in via USB - connect
3. Calibrate your Radio
4. Put the throttle in high position
5. Unplug usb
6. Plug In Battery
7. Lights on APM2 will Cycle (leave throttle high) wait til all the beeps
8. Disconnect Battery
9. Plug In Battery
10. Lights on APM2 will Cycle (leave throttle high) wait til all the beeps
11. Move throttle to lowest
12. Confirmation beeps
13. Unplug battery
14. Turn off TX
1. Turn on TX
2. Turn on Quad
3. Arm motors (lowest + right) watch leds. motors should arm.
4. give a little throttle to test
1. Disarm motors (lowest + left)
2. Unplug Quad Battery
3. TX off
Don't turn tx off before quad!
something apm2 won't boot with certain ESC apparently. if this is the case boot with usb power first, then try to hook up battery. disconnect usb and arm
Run motors command to double check outputs. :D Hope this helps, I am not flying yet. Still on hand tests/preflight with some issues I think.
Do you have to do that all the time?
ok, will check on the 1500 on the yaw. My lowest point seems to be 1100 and high about 1900 on my Futaba with 100% travel. Should I be lower then 1000 and the min and about 2000 at the max?
ok, this morning I went ahead and retried the arming without doing any changes yet. But this time, I took my time and held yaw right for little longer till I saw the blue/red light changed its blink sequence. I knew now it was ready. I tried it out, and the throttle worked fine. I have tried it for a few times and its working. Removed the batt and tried again. Still working. So, the problem was me not giving the APM2 enough time to arm.
I have the same problem... APM2 will not arm the motors... Some time I get solid blue light
Some times I get normal lights but still no arming..
This Fix works every time, for me...
Unplug the tail servo on my tri copter... Boots fine... test motors.. plug in tail servo... go fly..
btw... I have 5 amp BEC and 5.2 volts, measured all the time..
correction... APM2 arms the ESC sometimes... Has nothing to do with the tail servo.. !!
