Ah, that's it. Thank you very much.

Cheers,

Hi,

You also need to load the mavlink_decoder module with the proper settings.
Something like this:

    <load name="mavlink_decoder.xml">
      <configure name="MAVLINK_PORT" value="UART0"/>
      <configure name="MAVLINK_BAUD" value="B115200"/>
    </load>
    <load name="px4flow.xml"/>

Hi,

I want to use the flow sensor, but when I try to build everything I get the following error: /home/finken/paparazzi/var/Quad_Lia_ovgu/ap/modules/optical_flow/px4flow.o: In function `mavlink_register_msg': /home/finken/paparazzi/sw/airborne/./modules/datalink/mavlink_decoder.h:166: undefined reference to `mavlink_tp'
collect2: error: ld returned 1 exit status
make[1]: *** [/home/finken/paparazzi/var/Quad_Lia_ovgu/ap/ap.elf] Error 1
make[1]: Leaving directory `/home/finken/paparazzi/sw/airborne'
make: *** [ap.compile] Error 2

In the airframe I tried to load it like this:
<modules>
 <load name="px4flow.xml" />
</modules>

Do you an idea what might cause the error?

Cheers,
Dirk
