Based on the MAVLink Messaging tutorial ( https://dev.px4.io/v1.10/en/middleware/mavlink.html ) I followed all the step, but when I compile the code I get the error: error: ‘MavlinkOrbSubscription’ does not name a type in mavlin_messages.c.

It appears the example has not been updated. You need to file an issue. If you look at the 1.10 version of mavlink_messages.cpp is used there, but not on master. If you switch to the tag 1.10.1 your .h file is there, but not on master.

If you do this it will switch to that tag: [image] Also google “How To Checkout Git Tags”

Thanks! Last night I play a little bit with github and I was able to learn how to search a file into different version. Right now, I try to understand how to clone locally, on my linux machine, a previous version of the PX4. Best regards!

Well you could just download the zip file for that tag.

I used: git clone --recursive -b v1.10.2 https://github.com/PX4/Firmware.git px4-firmware_v1.10.2 but when I build PX4 v1.10.2 I get errors. Now I will tray with 1.10.1.
