Hello everyone pleasure to meet you all I’ve learned a lot from reading posts on my journey to use the Herelink on the Freefly Alta X.
So far I have configured my Alta (on the latest version v1.3) and connected the Herelink air unit to the external telemetry port. PX4 reads this port as Telem2 (conflicting with the documentation from Freefly). I also have a FRX Pro installed on this Alta X with that occupying the Telem1 port.
Using the FRX I can see that while powered on I still have a good SBUS connection as my stick movements reflect over telemetry on the FRX Pro connected to my laptop, however telemetry is not available on my ground unit. The baud rate I am using is 57600 on each of these ports, I have tried a number of different baud rates/telemetry modes without success.
In fact the only success I have had getting telemetry to the Herelink ground unit was very short lived. I was sitting here at my laptop with the radio and drone both powered on, and suddenly the telemetry connected to the ground unit without any change to the parameters. The ground unit tried to get all of the parameters downloaded but failed halfway through and disconnected again. This has happened a few times so far in the last few days of testing, once using a 38400 baud rate.
I should also note that I bought a separate Herelink and tested another ground and air unit with similar results.
So my questions for you all:
Has anyone else tried connecting the Alta X with Herelink?
Does the FRX Pro conflict with the Herelink?
What could be causing this intermittent telemetry issues on my Herelink ground unit?
Would I need to use the other internal telemetry port for the air unit? (removing the FRX Pro entirely)
Why wouldn’t Freefly support Herelink integration on the Alta X when their new drone will have it?
Thanks everyone for your time! Here’s hoping to get to the bottom of this one.
