Hi Dave,
You're very brave going 500-700meters away and hoping RTH works....I've tried it quite a few times from just 50-70meters away (LOS) and most of the time it works ok-ish but every now and then it just wants to "piss-off" in the opposite direction. Very strange considering I changed nothing in the two minutes between RTH attempts.... Keep your RTH switch finger ready just in case..!

Cheers,
Smithy.

My theory is that the board direction is determined by the GPS and HH is only used to establish a fixed position relative to a point in the horizon - similar to a helicopter heading hold gyro - does not matter what direction the heli is facing.

Update: Not a good idea .. instead of just drifting , on HH after a few minutes the quad starts to spin around. So for now, the board gets a well deserved rest and the MKT3329 GPS goes to the Crius AIO frame.

I found it in theOLD firmwares folder of my MTK_firmware_tools folder.

I rigged up my FTDI unit that I got with my HK MW SE 2.0. Took me a few tries before I realised I needed to hook the RX to TX and the TX to RX. Seems obvious now....

7 satellites under a tin roof! So chuffed!

The main board is running v2.1 firmware. Just uncommented the following lines under the GPS section of config.h

#define GPS_SERIAL 2
#define GPS_BAUD 115200
Would this one also work?

AXN1.51_2722_3329_384.1151100.5.bin

Also when hooking up your GPS to the FTDI unit, do you only have to hook up rx tx gnd v or do you have to use all 6 pins?

So... Am I the only one trying to get it working on ArduplaneNG?

I need people to brainstorm with. I haven't used the Crius AIO, so I don't know how well it outputs signals to APM Planner. So far it's reading the baro and yaw, but I can't get the GPS to show my location and pitch and roll don't do anything at all.

I put MultiWii 2.1 on there to make sure it all works and it was fine.

Hi Tim, You are correct. Only the RX, TX, 5V and GND.
Not sure about the firmware, I didnt use that one.

I used the "MWC Pro GPS (r33) Config" guide in the HK files sections. The specific file to use is the MTK3329_A1.5E_20110118_10Hz_115200.bin - I tried everything else but only this worked for me. It should be part of the "MTK-firmware-tools-for-2.1.zip" you can access as a link from the guide http://code.google.com/p/i2c-gps-nav/downloads/list . Go through the how-to flash PDF but transfer the two bin files (do not mix up the two) you will use to the same directory as the flash tool for easy access from within the tool. Somehow the tool errors out when it takes too long and this is the only way I got the green donut.

Ok thanks for the replies guys.

One more question on the GPS. Is there a GUI program for the MTK GPS like there is for the U-BLOX GPS (u-center)? Just to confirm that the GPS is running at 115200 and 10 Hz.

There is a file which called "Tiny GPS" (I can't confirm the exact name - sorry) included in the zipped file. Connect the GPS via serial to usb card and run the program. Connect to the 3329 (use the correct COM and baud rate) and you are given an option of warm/hot/cold start. If you are connected properly and the 3329 is working right (blinking circle), the GUI will start showing Sats and eventually you will get a fix. Good idea to be very near a window or outside to get good signals.

Can anyone verify if this board is as poorly manufactured as the KK2 board?? I had a pretty bad crash yesterday that ruined my KK2 board. No physical damage done, but now my ACC sensor no longer functions.

I am thinking of replacing the KK2 board with this board. But if HobbyKing continues with their poor soldering and manufacturing skills... i might have to buy my next board elsewhere.

But a bad crash can ruin even the best manufactured devices.

Did you try pushing down on the acc and see if it just not making contact anymore after the crash?

Yeah i did. I get some readings but the result is still "NOT OK"

Are these sensors that fragile & sensitive to impact that they will fail? Im thinking is just a weak solder from a company trying to save $0.03 in manufacturing costs.

Yea maybe a poor solder point. Even with the HK Mega board, we'll have to wait and see when people start crashing and if they'll hold up better than the KK2.

As mentioned previously, a crash can kill any board if hit hard enough or in the right place. I don't think HK actually makes these boards, my guess is that they are just a re-seller and the items are made elsewhere in China.
Mine runs fine so far although I've only had one or two minor "fall-overs", no hard crashes yet. I still find it very stable and nicely made, very adjustable via the WultiWii software too. Am using it for FPV and so far so good.

Cheers,
Smithy.

Yes, all the sensors are in fact delicate, if you crash hard enough solder connections may be broken [no matter who makes the board], PCB traces may crack, or the sensor itself may be damaged internally, the ratings for the sensors do have G force limits, exceed them and they will be damaged.
