I guess that i have two options left. 1. Use it w/o GPS for Stabilize and Circle or 2. Throw it to the BIN

I did it but nothing changed. Is there a way to copy paste what the serial monitor of Arduino is showing so as to check it yourself also?

Although a bit afraid to solder on a such small pad maybe i will try that and report back.

Theo, Connect the gps RX line to the Ap. If all went well, the Ap will setup the gps to 38400 and 4Hz. Open the gps cover and just solder one wire to the gps Rx pad, then solder  the other tip of the  wire to the Ap board Txo plug…

Is there a possibility that the high refresh rate of the GPS (10Hz) might be causing the problem?? I looked around the code under the GPS_NMEA tab and saw that the refresh rate can't be set over 5Hz. If i do then while compiling it pops up a…

I know it is supposed to work but..... I have tried with another GPS of the same type (Locosys LS20033) and it didn't work. I used this GPS on a FY-21AP and it worked. So the GPS is working properly. Unfortunately i don't have another…

Theo, If it is so (38400, NMEA output) try it with only GND, Vc and Tx connect to the Ap board. It should work!

The Locosys LS20033 that comes with the FY-21AP is also configured at 38400 baud rate by default. As per manual page 12 http://www.fpvflying.com/downloads/FY-21AP-manual.pdf The interface and features of the GPS circuit boardTX0：Data transmission.…

That is because remzibi osd gps unit works at 38400 (same as the Ap latest software) baud-rate by default, hence no need to configure the gps unit.

I asked because in this foto asks only for the Tx of the GPS to be connected to the Rxi of the Ardu. http://www.electronicarc.com/catalogo/product_info.php?cPath=43_80&products_id=423&osCsid=7aa040c7962b41f2b1a4023f77e0e7c8 And i got…

Theo, Check this photo: http://ardupilot.googlecode.com/svn/images/wiring_jumpers.png look for inferior left corner You need to connect (gps -->Ardupilot): 1. GND -->GND 2. Vbat +Vbackup  -->diode-->diode-->5V_out 3. Rx…

One more question. For the GPS to be correctly connected to Ardupilot what wires do i need? GND Vin Tx (of the GPS going to IN ) Rx (of GPS going to OUT ) is this needed too???????????? Vbackup

Stabiliztion works perfectly already. To do RTL i need GPS. Can you direct me to a link that show how to connect everything (That is IR sensors and GPS) and the correct Firmware so as to have Stabilization and RTL funcions?

Theo, I remember reading in the past some problem related with shield, gps and the led behaviour. Don't remember if the AP was operational or not with the led problem. Forget the shield, you don't need it to do FPV/RTL.

Maybe i have it all wrong, don't know what to say. I am connecting my gps the way it is shown in the picture below on the green circled pins. Is that correct??
