Re: [Paparazzi-devel] ardrone2_raw + flight recorder

[Christophe De Wagter]

If you use a SIRF GPS you must manually configure it to binary sirf protocol and sufficiently high baudrate. (there is no gps_sirf_center module yet to do this automatically for you)

The altitude of -4000 is because the baro's used to give relative pressure before while digital sensors give absolute pressure (on ground 1023hPa at sea-level).  A separate branch is addressing this issue.

Also, it thinks its altitude is -4157m, which is a little worrying :-)

If I switch the gps from ublox to either nmea or sirf, I get this compile error:

/home/ben/git-work/paparazzi/var/ardrone2_raw/ap/firmwares/rotorcraft/main.o: I\

n function `main':

main.c:(.text.startup+0x7c): undefined reference to `gps_ubx_ucenter_init'

main.c:(.text.startup+0x42f6): undefined reference to `gps_ubx_ucenter_init'

main.c:(.text.startup+0x62da): undefined reference to `gps_ubx_ucenter_periodic\

I presume this means I need to change more config somewhere - any hints?

So, actually, I can fix that, by removing this line:

    <load name="gps_ubx_ucenter.xml"/>

but ... I don't get GPS in the telemetry. For now, I left the flight recorder in its default mode, which is, I believe, NMEA and 4800 baud, so I set the gps to nmea and baud rate in  the makefile to B4800. I've confirmed that I can speak to it from sirf center with those settings.

Now what?
