Problems with Naze32 and Ublox Neo-6M

[louisdelooze]

When I enable the GPS in Cleanflight, my CPPM receiver does not work anymore, It blocks at 1500 thanks for helping me !

Do you have the GPS on UART1?  It needs to be on UART2 or softserial ports.

It';s on UART2

[quadfather]

That';s odd.  Can you give a bit more detail about what happens?

Does it freeze the RX as soon as you enabled GPS in the configurator?  Or once you arm the board?  Or when you select a GPS flight mode?

My rx inputs freezes when i connect the gps not even if i enable it, when i enable the gps, the sign in cleanfilght is green, but my rx stays at 1500. I tried to change the mode to quad but that did not help.

I don';t understand why the receiver would seize up as soon as you connect the GPS.  To me that suggests a power supply problem or a hardware fault.   

Do you have the basic knowledge to wire up and configure the Naze, or did you just follow some Internet post?  It';s not a judgement!  I';m just asking so we don';t tell you stuff you already know, or assume knowledge that you don';t have.

How are you powering the GPS?  Mine is taking power from the motor output rails on the Naze.  The Naze itself is powered by a dedicated BEC.  If your Naze is powered from an ESC try another ESC or consider a dedicated BEC, at least for testing.  Also might be worth checking the voltage you supply to the Naze with a DMM, it should be 5V or very close to it.

[louisdelooze]

For testing I used
5V usb for the Naze32
5V ftdi power output to gps
4 AA battery pack for receiver,

And i';m a bit new with the naze32 but I already did use a KKMulticopter and Multiwii, I have also programming and electronic experience (arduino, raspberry pi, etc)

[louisdelooze]

When I connect the power for the GPS to the naze there is a red light that goes on.

some screenshots,
(The foto where the receiver inputs are, are frozen.)

It is not the receiver that freezes it are the receiver inputs on cleanflight.

Untick the GPS boxes in Softserial.  You';re not using softserial.

Is your GPS configured to run at 115200 baud?  The factory default is 9600.  I set mine to 57600 using u-center.

Try to power everything from the same power source, e.g. use a UBEC or ESC to power the Naze.  That will also power the RX.  Then tap into the power rails on the motor outputs to power the GPS.  Double-check that whatever you use doesn';t exceed 5.3V.  It';s safe to power the Naze with 5V and have USB connected at the same time.

Is 115200Baud to fast ? I set it to 115200 in U-center

No, it should be OK.  I was just saying what I had mine set up as.

Could it be a faulty Naze32

[quadfather]

Could it be a faulty Naze32

It';s possible.  Did you try my suggestion about powering everything?

[louisdelooze]

It';s possible.  Did you try my suggestion about powering everything?

Yes, so i connected my ESC to the Naze32 and I connected the GPS power from motor input 6, I powered the RX with PPM + My Naze32 is connected with USB

And do you know what that red LED means.
Thanks for all the tips !

Which red LED?  My NEO-6M has a red LED indicating it has power.  The red LED on the Naze means that you have a stabilised flight mode selected, e.g. Angle or Horizon.

I mean on the naze32, weird because it is not on, the led only goes on when i plug the gps in, normal ?

No, I';d say not.  Mine doesn';t come on when I plug in the GPS, only when I select stabilised flight modes.  I';m on CF v1.9.0, but I don';t think this is something they would change.

After searching and searching....... I finally found the solution. There was a small chip near the RX connector and because i';m a genius I bridged 2 pads =D When I was soldering, with the help of a desolder pump I removed the solder and it worked !!!
