APM 2.5 and 3DR GPS uBlox LEA-6 - "NO GPS" problem in Mission planer - Discussions

Hi!

I build kit arducopter quad, and go to test it.

But GPS don't work.

I try everything,

1 reset APM,

2 erase APM,

3 upload 2.8.1

4 and 2.9.1

5 I test every pin and wire from Ublox module to APM board, all OK

6 I upload Firmware 7.03 to Ublox, and upload config to Ublox

7 I test Ublox works fine with u-center 7.02 and lock sattellites

8 I connect Ublox to APM, and "NO GPS" message still appears.

9 I use Terminal, TEST>GPS , and only dots ........

I think problem with APM.

I don't know what to do.

What do you recomend to me ?

Did you solve your problem?

I just received my LEA-6h with firmware 6.02 and I don't know if I should upgrade to 7.03 like you did.

I just bought AMP2.5. "No GPS" for me was because I used wrong cable for the old style GPS. After I used right cable for the new style GPS and plug in to the right port, I made my GPS working. Hope this helps.
