Hello, everybody !
I am interested in GPS use for crazyflie. I bought UBLOX MAX-M8C-0-02 but did not succeed yet to be able to get correct functionning.
Furthermore, I did neither find GPS tab in last version (2017-04) of python client nor gps branch in master branch. So I understand I have to use development branch, is that correct ? Have you any help to give me ?

Hi,
The GPS tab, it was using open-street-map and died when mapquest stopped making free mapping tiles available. Because of this and that we have not seen much interest in the GPS tab not much has happened. If you would like to give it a shot that would be great because as of now we don't have any tome to spend on it.
These is also a long thread about GPS development here but it has been a while sine it was updated.

Hello !
My primary goal is to obtain geographical coordinates on GPS tab. Nothing more but not so easy for me.
The steps are:
1/ obtain GPS tab in main gui, using Qt5 library,
2/ display the values on the tab,
3/ display a map, in a passive way, no interaction with GPS data.
All this is now correct. But I did not succeed yet to obtain the 4th step : get a fix from the GPS receiver and the corresponding data. Gui client obtain only 0 latitude, 0 longitude, 0 height(MSL), 0 satellites, etc...
I used technical information from Ublox.
Despite the fact that Jackemoore's gtgps-9 branch is dedicated to Titan receiver, I used it to obtain more information on the console and I fix GPIO pins in gtgps.c with this code in
DeckDriver gtgps_deck with:
.usedPeriph = 0,
.usedGpio = DECK_GPIO_TX1 | DECK_GPIO_RX1,
... I probably miss something.
But no fix after 5 minutes.
Next step will be to write red an blue circles on the map...
My work is now on Github, under the name "Mitteau".
Sincerely
Jean-Claude

Re: GPS
Yes, it's a chip antenna. Perhaps also too close from crazyflie circuits ? Only 15mm.
I have a Garmin sport watch which fix satellites without problems, I think it is a chip antenna. I have not open the watch.
I am making a special tab too dialog with STM32 through radio link.
