I just bought an ArduCopter Kit a few weeks ago and finally assembled it. Now I have some issues communicating with the board via the APM Planner.
Here is a bit of history of my problem:
1. I was able to connect, download and configure the software using APM Planner
2. I setup the RC, ESCs and everything else successfully
3. I've assembled the kit completely and was able to arm and control my servos fine
4. After swapping the ESC connections to configure the correct direction for all motors. Reconnected to battery and everything worked well.
5. Installed the propellers and connected the batteries. Some ESCs start beeping and the servos were twitching
6. After that I could not re-arm my ESCs but the RX was working since I've seen the send blinking
7. Disconnected the the ESCs and battery and tried to re-program the board. Then I realized i cannot connect anymore.
Here is exactly the symptom i got now:
Can somebody help me figure out what's wrong? There is nothing more upsetting than having everything work for 10 minutes and then stop...
I want to mention that I've tried connecting with different USB cables, have no driver or connectivity problem as I was able to communicate well with this board initially.
Does this point to a bootloader issue?
Is there anything else i should test, try, measure to provide more insight? Any thoughts?
Thank you very much for help,
If you can connect again via the CLI, do a "reset" in the setup menu. If you can't connect via the CLI there may be an issue with the hardware and you should arrange for a return/replacement from the store you got it from.
This sounds similar to problems that we had.
As a test, try to load the code and do a setup using Arduino.
You can also try to load the PiratesNG code, although that code is limited to just flying, and no navigation.
If you download and install the code/Arduino, you will find Arduino based examples that let you test each of the sensors on its own.
Then, if you can return the boards with not too much hassle................
Did you fix your soldering or your problem at all? My USB cables and connection seems to be OK, but I got the same problem. Please let me know of any idea.
I have the exact same issue and I've noticed that playing with the USB connector help me to get it connected but only a few second unless I hold it on a very precise position .....
For that price of hardware I guess we could expect a bit more than a 35cts USB connector not able to hold the cable correctly ....
I ve been through forums and have seen that quiet a lot of people have an issue with that connector.
I guess I am on my way for a RMA ......
Hopefully it wont take too much time, so frustrating ...
my connector is fine........ do i have 2 bad cables that got ruined at the exact same moment? probabilities are low.
I did. should i send both the IMU and the oilpan?
Hello agmatthews, Thanks for you answer, I ve contacted the support to ask them if I could do that :)
I've the same weird problem,
and in addition, I can't do a physical Reset on my board IMU (nothing happen even if I do a reset on the red Board APM with a tiny wooden stick).
So, I've tried 2 things maybe that can help you for the diagnostic:
If I open with arduino the serial monitor, nothing happen even if I'm right configured (CR and Bd rate)
but when i Hit the button Send, the TX Orange Led on the IMU sensor board flash.
I've tried to enter "reset" but nothing happen.
Thanks for helping :)
Your board reaction looks similar to the reaction of my old board. I tried everything on mine, I even bought a programmer in order to re-load the bootloader, but nothing worked.
Lots of people solved similar problems to yours by re-soldering the USB connector, did you check if yours is OK?
