Still broken:

Firmware built using:

make CONFIG=SPRACINGH7RF

[hydra]

Maybe this screenshot helps?

There's duplicate data in self._features at the time FC.FEATURE_CONFIG.features.generateElements(featuresElement); is called from recieiver.js

[hydra]

The feature is already present in the list, and then some code which looks at buildOptions (which I'm not familiar with) adds it again.

I'm not sure why the code in Features exists (the bit that does // Add TELEMETRY feature if any of the following protocols are used: CRSF, GHST, FPORT), perhaps you could shed some light on it? How is it possible to build firmware that doesn't include the feature bit? Surely that's the root cause of this and where the fix should be applied?

In 4.4 we used build API to retrieve build information to retrieve options included
In 4.5 we can retrieve them directly from firmware.

As for 4.5 the telemetry options are not available in firmware so have added them afterwards in software to display telemetry in receiver tab.

Thanks for the info.

I'll leave the fix up to you guys, you should have all you need to replicate the issue and verify the fix, if not let me know. Please ping me if there's an updated fix for me to try.
