4. Description of your issue:

I would like to implement the stratux GDL90 protocol but I am unable to find a documentation for the AHRS Report message. Example of such a message:

7e:4c:45:01:01:00:00:00:00:00:00:00:00:00:00:00:00:7f:ff:ff:ff:7f:ff:7f:ff:b7:49:7e

Would be nice to point me to the right place in the world-wide web.

Stratux has different ways to report AHRS. The most common one is probably the Foreflight-like message. See https://www.foreflight.com/connect/spec/

Thanks, I found this documentation and I have already seen such messages. However the message in question - which I receive at a regular interval with the newest stratus-build - starts with 4c:45 ("LE" in ascii).

7e:4c:45:01:01:00:00:00:00:00:00:00:00:00:00:00:00:7f:ff:ff:ff:7f:ff:7f:ff:b7:49:7e

I found a mention of this prefix but the link to the mentioned sourcecode is not valid anymore. cyoung#332 (comment)

Update: I viewed the project at this time (good to have a rich git-history) and found the mentioned sourcecode:
https://github.com/cyoung/stratux/blob/dbca0fb0b08e229b3656288f1a39eaf6ed00564b/main/ry835ai.go
Seems the method at this time was makeAHRSGDL90Report().
Where can I find this implementation in the current sourcecode?

Whereas I am now able to implement the message (hoping that the content has not been changed since then) a documentation about it (and links to the other documentations) would be nice.

Again thanks for your quick support!
