@Djalma-Ribeiro Awesome thank you, just wanted to make sure your RB5 had the SDK loaded properly, which it does.
It's not absolutely necessary to upgrade the SDK, if you do want to you can follow the steps here: https://docs.modalai.com/Qualcomm-Flight-RB5-sdk-installation/#how-to-upgrade
One note, if you try to upgrade the SDK while PX4 is running it will fail. So in order to upgrade the SDK you would have to disable PX4 from starting systemctl disable rb5-px4-start and then reboot your drone before upgrading your SDK.
