MultiWii

I just received my House uBlox 6M GPS Module V2 from RTF Quads and I cannot get any data from the module when connected to my Rev 5 Naze32 board.

The module has power, and I've doubled-checked the Tx/Rx connections as per the example photos.

In Baseflight I have GPS enabled, GPS type set to 1 (Ublox), and baud rate set to 0 (115K)-- all correct as per RTF Quads -- but when I view the GPS tab in Baseflight the lat. & long. coords are all 0's and it says my altitude is 65519 m (woohoo!). I also have GPS enabled on my MinimOsd board but no GPS data is being received from the Naze32.

Radio is an FrSky Delta 8 set to CPPM mode and everything else appears to be working correctly.

I've included my settings from the CLI for reference.

Anyone else run into this, and if so were you able to resolve it?

Sounds like a stupid question but i am guilty of this mistake - have you got the battery plugged in or just powering from the usb?

Not a stupid question. Always with battery.

; )

RESOLVED.

In the Baseflight GUI under the 'Configuration' tab is an option for "Enable GPS (PPM or 3rd serial port required)"

The keyword here is "or" which needs to be changed to "and". I had PPM enabled but that was not sufficient.

Once I enabled the 3rd serial port the green light on the GPS module began to blink and coordinates started streaming in.
