Has anyone successfully used the APM2.5 (or other APM) with the cheaper NEO-6M ublox gps ?
Did you need any modifications to the source code ?
Thx !

i,m trying again today, i have tried to use the tele and power it up with the wall charger i place the antenna of the gps far away from the tele and still NO GPS on the planner, then i plug the apm to the pc still with the tele connected(which will not work because of the usb) and i got GPS NO FIX so obviously is the tele the problem, how you guys suggest to resolve it?

Heres an example of my exact problem
ok people just a little help for those who have gps lock over usb but no lock on main power.
There are two possible causes to no lock on main power, firstly the amp internal power circuit is not high capacity so if you have everything powered from the BEC's of your speed controllers, if they are low current becs you will find that the power is insufficient to power the whole board, at one point i had a bard that worked until the motors powered on, at which point it would loose its power and brown out.
Secondly you may have interference, the stock gps is very sensitive to interference from the motors and even from the wires running to the ESC's, so make sure to mount it at least 2 inches away from wires and even further away from the motors.
Guys, i am having huge issues with the uBlox GPS modules. Ive had 2 APMs with 2 different GPS modules and both times, the same results.
I am getting a GPS lock on USB ONLY. No lock whatsoever when powering off a 3S 6000mah lipo. Ive checked the voltage under load on both battery and USB and there is .10 of a volt difference. I have tried powering the GPS unit using a regulated dedicated BEC with no luck! As soon as i plug in USB, a lock in under 60 seconds, on battery it just flashes for 30 mins + with satcount of 0
So, i pulled out all the ESCs from the APM to make sure there was no noise being supplied by one of the ESCs BECs. Used my regulated BEC to power the APM and same thing.
No matter what i do i am unable to get a lock on battery! Very odd and frustrating problem!
Any help much appreciated!

I've tried to upload 3DR-Ublox.txt to Crius v2.0, but got errors like this:
Sending: CFG-PRT - B5 62 06 00 14 00 01 00 00 00 C0 08 00 00 00 96 00 00 07 00 01 00 00 00 00 00 81 84 ...
... timeout occurred without receiving an answer. Retrying...!
Than I get View->Messages view->CFG->PRT->1-UART1 and changed BaudRate from default 9600 to 38400.
Uploaded ok!
P.S. You need to press "send" in the down left corner. It is in unusual place and hard to find or to guess, but you have to find press it for settings to take effect:)
