MultiWii

I do have a U-blox GPS, it is the same problem there. I have also tryed diffrent FC of the same kinde. I cant get theublox center or minigps to work, have an ftdi adapter.

Where in the code do i offset the compass ? I just recalibrated the mag and it is pointing north on the map when the tri is pointing north. Still the problem with the poshold being in the ocean, i set the home position and poshold to the current while the tri was armd throw the BT but that did not h...

Are you sure that the servo works? Take a lock in your code and see what frequency you have set the servo to.If it is a analog servo you should have 50-100 Hz

The FC is mounted in the correct direction. But alright if i offset the compass the tri will fly to the ocean. How do i get it to place the poshold in the current position and return to home in the start position and not the freaking ocean? Could this be manipulated in the code? If so where in the c...

Just did some more testing and upload more pictures in the dropbox: m I am really confused now. First of all, if you take a look at the map picture you can see poshold point somewhere in the ocean far away from me. I tried to setting pos and home in the same position the tri is in (my backyard) but ...

I had the same issue, try holding the reset button on the FC and press upload on the PC. When you se the uploading in audrino relise the reset and It will upload just fine.

I did fly the tri during the summer many times, it flies well. Did also use the headfree function to comfurm that the mag works and i wored like a charm. So everything works great as long I dont use any GPS functions.

But as you can se in the pic, I do have 7 sats lockt and a home position.

Did some test to see if the compass change with high throttle. It did not. I had the BT on during the test and here is some pictures: m Moved the multiwii higher up but still the same problem. One of the motors goes full throttle when i turn gps-hold on. So i disarmed the tri and rotated it 90-degre...

The compass and Mag are calibrated.

ok so lets say that the mag is the cause to this problem, who do you explane that the bluetooth dont work? It is not effected by the functionalty of the mag.

I am using the HK Multiwii PRO: m After a day with product support i did get a new board but still the same problem with that one. I have tried the MTK and ublox GPS. Same issue on both. Did make a test run where i had all the "hot" wires over 15 cm away from the gps and still the same pro...

Well i have the same problem when i have 9 satellites locket.
I am having trouble with the Bluetooth adapter too. I can se the device and pair whit it and connect but it wont transmit or revive, did try to change the TX, RX but did not help.

Because it is not operating correctly. Wvry time i turn on the GPS-hold the quad takes of like in this video: https://www.youtube.com/watch?v=UJrErUl ... H7&index=3


Magnetic declination is set and the compass is calibrated.

Having trouble to change the baud rate on the gps. I have connected it to the pc using an FTDI unit. I don't want to download the ROM file using Flash tool V1.0 Tried Tera Term to se if i can get any info from the gps at all but it don't print any text at all. I know that the gps works because when ...

Ok i have got the FTDI cabel but i cant get it to work whith mini gps.

The Tx of the GPS is going to the Rc of the FC.

I have no way of controlling the gps data but i do have an FTDI cable on the way so i can check that and perhaps change the baud rate of the GPS.

This is my Code. Do you see anything that should do to it? There are several i2c parts which of them do I need to undefine? Config.h --> #ifndef CONFIG_H_ /************************** The type of multicopter ****************************/ //#define GIMBAL //#define BI #define TRI //#define QUADP //#de...

So if I have the wrong baud rate on the GPS and I still gps locks does that mean that the GPS is sending wrong type of data to the FC?

And what if i have the i2c defined when i am not using one, does that effect the gps somehow?

Same thing with #define MTK_BINARY16.

Well i am using the stock MTK GPS and if i change the config.h for the GPS baud rate to 57600 i get satalites loced. Do i reaaly nead an I2C bord for the MTK3329? Here is my gps code: #define GPS_SERIAL 2 // should be 2 for flyduino v2. It's the serial port number on arduino MEGA //#define GPS_PROMI...

Hi, i have had a problem with the multiwii pro since i got it. The issue is that i can’t get the GPS hold to work. I have tried different gps modules and multiwii board and still the same outcome. This is my board: m When i turn the GPS hold the rear motor on my tricopter goes to max throttle. I hav...
