Px4-autopilot: Auto sensor reading after pixhawk startup

[bthnekn]

Hi guys is there any method for sending messages through mavlink console while pixhawk startup or when pixhawk armed.

ı have a sensor called usharp patch from aerotenna like ulanding radar distance sensor ı am reading data when ı write "usharp_patch start" to the mavlink console and watch the data with analyze section. So ı am wondering can ı send that "usharp_start" message to mavlink console when ı power the pixhawk?

Well, maybe changing flight mode features will do that but ı dont know how to change flight mode features either.

btw sensor's driver is uploaded to the pixhawk but ı dont know who did that ı'll publish the driver as soon as find the driver file

Do I understand correctly that you just want to do a nsh command on startup to start a sensor?

If you're already compiling your own code, you can add the command to the startup here:

Yes just try to add a new command. Normally I write "usharp_patch start" command manually via mavlink console in qground control.What I want is actually this starting process of the sensor triggered with startup like the compass or gyro (sensor dont need calibration btw)

Thank a lot for your help ı will examine your link
