i can't download any log files ,
i'm using apm 2.8
rover 2.5.0 beta
mission planner 1.3.50
when i try to download data apm will disconnect and to be able to connect back to it i have to unplug the power.
sorry for my attitude but i arrived to a point where i spend so much money and time to build a toy to play maybe 1 hour and after that just put it away and do something else but until i will put it away i can't make it work... the whole reason why i'm so frustrated is because to order another board an upgrade like px4 it will take again a full month to arrive from aliexp and i'm just going mental. Why i haven't done this from the beggining? stupid i'm
After throwing the apm to bin ... i took it back reassembled it again and sterted measuring bit by bit all signals etc. What i successfully done is to make the boat travel to the waypoints but in a very bad behavior ... it goes in half circles on it's way to the waypoint. I attached a photo simulating apm's behavior.
The other thing that really makes me mad worst than i ever thought i can get ... is that the ESC get's some crap signal only when the boat is on water and only when the esc is connected to OUTPUT APM (3 used for throttle).ESC connected to RC receiver works perfectly, never stops. Crap signal means that the boat stops after throttle gets above 1700 PWM. This behavior on water is like this ... boat travels one meter after that stops. If i take the boat out from water and put it on the ground and set throttle above 1700 PWM nothing is wrong. You will say that the motor is not powerfull enough to drive in water but believe me that above 1700 PWM and even arround this value i can't stop the motor with my hand on the shaft, and if i manage to stop it pressing hard, the motor still tries to get forward, thing that on water is not happening , on water i have to bring stick to neutral position and move it up again. I've seen some videos on youtube ... people experiencing ESC not sync and the issue was because ground cable from signal connector wasn't connected to ground APM. I done this and still same issue. All i can think about is that the ESC gets some crap PWM while the boat is on water and because with apm 2.8, rover 2.5.0 can't do any esc calibration ... i think the apm will go again to bin... Apologies but is just going forward backward with the apm 2.8 to bin :)))
First suggestion came from TCIII user who said that the esc 12v + - should not come out from TO ESC pin from 3DR power module. Followed his suggestion and connected ESC 12v + - to Battery. Nothing changed
If you have any suggestions please let me know !
