I just received the Full ArduPilot Mega kit it came from DIY Drones store about 1 month ago, (The Arduino compatible ArduPilot Mega platform-The IMU sensor shield, better known as the"Oil Pan" Revision H) with the Triple Axis Magnetometer soldered onto the board. It came with the "MediaTek MT3329 GPS 10Hz + Adapter Basic" which is plugged in .
I loaded the Aducopter quad 2.5 firmware using the latest missionplanner 1.1.56.
I am only testing it first before I try to fly it. Everything seems to be working, except for the GPS.
I have the oilpan connected to a spektrum receiver and all the functions seem to work, but the GPS does not. I have tried it outdoors and it doesn't have any lock. The GPS status is 0. The GPS light goes on when I power it up, it doesn't blink. The "A" and "C" (red) lights blink alternately when powered up (I guess it is initializing?) and then the "A" light continues to blink (to show disarmed).
There doesn't seem to be a setting on the missionplanner to activate the GPS.
I don't really know what to do to fix this problem. I have tried loading the firmware using the Aduino program with the same results. Somehow the GPS needs to be enabled, but I don't know how to do this.
Do I need to arm the oilpan before the GPS will work?
There is no setting to activate the GPS, it just works but due to the solar storms and aging GPS satellite fleet, GPS signal is very week and is hit or miss indoors with any GPS receiver. You can tell if the GPS module itself has lock (aquired enough satellites) when the led on it goes solid, blinking means no lock or fix and thus you won't get any position data.
Just thought of something since you said you went outside, are you sure you plugged the GPS into the correct port????? One says NOT GPS!!! make sure it's plugged into the ardupilot (red board) not the oilpan (blue board).
The problem is the GPS never blinks. It is always on when I connect power to the oilpan.
OK, it's a standalone device for the most part which sends the ardupilot data so if it has power it boots, blinks and then goes solid. Assuming good power, it sounds like a defective GPS. Call DIY drones, they are extremely helpful on the phone. In this case, I think you have enough justification that it's a bad part. Again, the GPS is largely standalone, so unless you plugged it into the wrong port and fried it, I would pretty much have to assume it is in fact bad. The only other way to know is to rig up a FTDI cable and try to communicate directly with the GPS and see what it's putting out.
FYI this is an old thread on GPS problems and maybe some answers of how to test further are in there.
I was afraid of that. I am in Brazil and it will be very difficult to return it.
I did follow the instructions exactly, and did plug it in correctly. Ok, I guess a call is in order soon.
Here, try this first to be sure
There is a test for GPS from the CLI in the Mission Planner. This should help determine what's going on.
Maybe this too
