Veikko Vierola replied to Garth Tissington's discussion APM1 MediaTek GPS errors"Try it again in an open position so that the buildings will not disturb the GPS signals. In the init phase the GPS HDOP/VDOP is always wandering around a bit but the error will be smaller according to time."

My quad flies just fine in Stabilize mode. Very stable.However, when I try auto mode. It becomes very erratic and in the most recent test I didn't get back to stabilize before it came down hard. Only a broken prop :-)I have the log file and I've been trying to understand what it is tell me. IT has thousands of enties and I just don;t know how to read it. I have searched and read the blog posts and even found the "APM Log visualizer" (which seems to have problems with APM1 files) but…See More

Garth Tissington replied to Garth Tissington's discussion Reciever Inputs not working"Thanks Chris,
I'm going to assume you are an employee of 3drobotics?
If not, you can just ignore the rest of this message. I have a little timing problme with RMA return.repair. I've sent the following email to the customer…"

"Thanks for checking all that--you're not showing any connection at all. Your power/electrical connections look right, so I think this board needs to be replaced.
Sorry about the hassle, and thanks for your patience in the debugging.…"

same result.
Here is the log of what happens when I click connect

3D RoboticsChris Anderson replied to Garth Tissington's discussion Reciever Inputs not working
"Can you try another PC and USB cable? If that doesn't work, you may have a defective board and should contact customer support for a RMA and a replacement. "
Garth Tissington replied to Garth Tissington's discussion Reciever Inputs not working"Yes, I believe that is how I have it connected. But maybe you could double check.
I have confirmed that the rx signal/+/- are correct. I've already tried another USB cable. I guess another PC is my last option. Alas, I…"
Garth Tissington replied to Garth Tissington's discussion Reciever Inputs not working"Well, it's not always crc errors. Just generally garbled text on the terminal session. Then either lost packet errors or crc errors.
I reinspected every solder joint. No sign of anything that looks suspicious. So I went…"

"Can you describe how you're powering the board? For APM 1 on the benchtop, it should be:
--USB to APM
--Fully charged LiPo powering the RC rail via an ESC.
--If you're got it on a multicopter, you should disconnect the four-wire…"
DeveloperMichael Oborne replied to Garth Tissington's discussion Reciever Inputs not working
"When connecing via usb, you should not have any crc errors, or only 1 or 2. if you are gtting more than that verify all your soldering for dry joints and shorts.
Michael"
Garth Tissington replied to Garth Tissington's discussion Reciever Inputs not working"I think what you see in the terminal session is just messed up communications.
If it was doing this from the start I'd have guess it was a bad solder joint. But everything worked fine for a couple of hours.
Anyway, this is what I get…"
