oops sorry. Possible to move in the right sub forum????

Hello multicopter geeks I am opening this new topic to get your opinion on the "best" configuration to build the quadcopter for "everyday" flight What parts do you prefer to fly with - Flight controller - motors - ESC - GPS device - MVC version - additional sensors - if flying wi...

Hi Dramida
Great news. This is the end of our difficulties

Do you think the ublox should be covered against the sun light? Hi vpb. No GPS is really no sensitive to sunlight. Only to "exceptional" solar activities. Hopefully this are rare events and this is mostly predictable in advance. Hopefully because many flighing assets are using GPS nowaday...

About POS HOLD with GPS, just one time I saw it's nearly locked to one position (with baro, ofcourse), all other tests showed that it went around about 1-4m. I intend to do POS HOLD PID tuning explained in EOSBandi document. The RTH feature works great! Hi vpb Since Baro is important for the POSHOL...

Still dont know why I cannot config my gps to work at 10hz/115200 with quadwalker 's instruction, (solder pin 13&14&15, 13&14, de-solder all, solder & desolder battery ), maybe I'll try again sometimes. Thank EOSBandi & quadwalker ! Hello guys Sorry long time I had no time to up...

Hello When PosHold and AltHold are activated, do you have your position well kept? In my case, my quad is flying slowly to the left, mostly 5 or 10m from the position I activivated then he is coming back to the position wanted but staring again going back to the left and backward as well. After 2/3,...

Are you using this and have the ublox with the pins 13,14 and 15 soldered? I changed the I2C sketch to perform the same and so far the only remaining issue is the damm GPS not starting at first try. Hi iceWind. I only have pins 13 & 14 soldered together. Pin 15 remains unchanged. My GPS is a Ne...

I mean even horizontaly. The quad is realy moving 5m in any direction from the position I'm switching on POSHOLD

EDIT.: I tested with my LEA-6H in my Crius ext. board, looks like it's not working... nothing serial from GPS. Changing back to 58600 it works. For ALT hold sensitivity, change this value in config.h: #define ALT_HOLD_THROTTLE_NEUTRAL_ZONE 20 I'm using my copter with 80 value instead of 20..... HI ...

Looks like it works for the Ublox LEA-6 module on the Crius Extend board as well. Don't forget to change the SBAS setup in GPS.ino for you area of the world. Also remember, that altitude is set to centimeters, not meters in this version. Great if it is becoming more and more "Generic" Cor...

For those who would like to test using UBLOX Neo 6m at 115200/10hz, here the GPS.ino attachment file modified As my Neo 6m gps seems supporting this rate, let's have a try from you side if you wish The GPS.ino was modified to scan 115200 as well during the the GPS init phase to setup the binary mode...

Hi Dramida .... In my case if it was having an ascending or descending behavior, it is continuing to go up or down even after switching the POSHOLD!!! I probably misunderstood something POS. HOLD. will hold geographical position of your multi and not altitude. For that you need properly tuned ALT. ...

Hi Andrej

Yes I saw that thanks to dramida. I was missing the GPS.zip attchment. Anyway, it was funny to test by myself and learned how all that stuff is working. GPS is a real magic box
cheers

Hi Dramida I made a test this morning to see the result on the fisrt plug. After 2/3min I got my GPS active. Red and green leds were "dancing" pretty well FYI I have soldered only pins 13&14 together I need to learn now how to use the POSHOLD. When flying and switch on the POSHOLD, is ...

I think that it can work at the fisrt boot. I need more time to test since my code was working until tonight From what I read, working at first boot is due to joining together pins 13 & 14 I will keep you informed but normally nothing very fundametaly different from Bani's code except he ensured...

HI Dramida THanks. I didn't figure out that an attachment was available in the EosBandi post. His code is pretty nice From my side, using 115200b and 10hz seems to be working. I can see working well in u-center but also when inside the FC my red and green led are flashing pretty well and in the MWGu...

Hello I have Crius GPS and FC AIOP and I've made the nice modification by soldering on the GPS the pins 13&14 together This is working like a charm. Starting from default 38400baud and setting 115400baud/10hz from the MW 2.1 software modified. So no more problem due to the lack of power for the ...
