BT telemetry - wrong measures

Post by Pyxis »

Hi all,

I succeded to wire and configure a HC05 module into my 9XR-pro to use it for sending data to Telemetry viewer android app, so far so good :)

But as you can see in the attached picture there're two wrong measures (all others are quit good ;) ) : battery percentage and altitude, maybe is there a relationship with my last demand to display correctly Alt and Bat % (especially) on the telemetry's dashboard ?

Any idea ?

Thanks a lot in advance !

For altitude, the raw value is sent to the BT module, while the displayed value is changed by the altitude set as the zero height, either by using the "Reset Alt" option or by the first valid height received.

For the battery %, do you know which value is actually correct?

So the displayed value on the app should change as soon as "Reset Alt" is selected but it is not the case. While on the 9XR telemetry screen "Alt" goes to zero normaly

Regarding the battery %, the 9XR telemetry screen displays the good value, not the app

Last thing I forgot, the modes texts don't match at all the real status of the UAV (stabilize, loiter, etc.)
