Mavlink communication

SHofmeester

Hi,

We had a C program running on our VOXL 1 that has always worked, including on image-version 3.8.0 with voxl-suite 0.7.0. But on the newest version 4.0.0 with voxl-suite 1.0.0, it doesn't work.

The program receives mavlink messages using MPA and voxl-mavlink-server. It is based on the voxl-vision-px4 module that handles mavlink IO to/from PX4 (https://forum.modalai.com/post/5026).

When we flash the image on the VOXL, the mavlink program still works. But once we use opkg update and opkg upgrade, it doesn't work any more.

Did anything change in a recent update that could have an effect on this program, like something below?

#define PIPE_SERVER_NAME		"i2c-mavlink"
#define VOXL_IO_CH				9
#define I2C_MAVLINK_CH			4
#define I2C_MAVLINK_PIPE_NAME	"mavlink_to_px4"
#define VOXL_IO_NAME			"voxl_i2c_mavlink"
#define VOXL_IO_LOCATION		(MODAL_PIPE_DEFAULT_BASE_DIR VOXL_IO_NAME "/")```


Thanks in advance!

@SHofmeester VOXL1 isn't fully supported with SDK 1.0 so I wouldn't expect things to work just yet.

The amount of time from voxl-suite 0.7.0 to 1.0.0 is a few years so I'm sure there is a long list of reasons why your program no longer works
