Have you installeed drivers for FTDI USB<->SERIAL on Windows?( Drivers page )
Here is the connection diagram with color of wires on my CRIUS CN-06
[GPS side] [FTDI side]
GND --------black-------- GND
RXD <------green--------- TXD
TXD --------yellow------> RXD
Please note: colors of your CRIUS cable may differ from my one. Please refer to pins assignment label at CRIUS board.
You should NOT connect to USB directly! You should use USB to SERIAL TTL converter based on FTDI chip.
which config file do you mean? What I know, I always check, whether is SBAS configured for EGNOS and I leave there in configuration just first three relevant EGNOS satellite because that fourth one in from my locacation invisible. R.
I tried using these files from this thread with NEO-6m and APM 2.5. I'm also using firmware 2.9.1b. When i use loiter mode my quad sometimes towels in a direction like the gps is telling the apm its position has changed drastically. I also live in europe and this GPS cant use galileu satellites. I didnt had this problem when i used LEA-6H with MPNG
so i have to program my APM with arduino right? Never done that although it must be easier comparing to MPNG. Does the NEO keep its setting if it looses the battery? I just have t put AP_GPS_UBLOX_cpp on the libraries? Is that file safe to use? Did you experience that toweling movent after loitering for a bit?
