• Added a fix for the OpenTX Integration of Servo Frame rates

• DIAGNOSTIC: in the Vibrations tab added the new value “Global Vibrations” that correspond to the vibrations area / surface and must be lower than 200
• DIAGNOSTIC: in the Vibrations tab changed the grey area to evidence the vibrations at low frequency
• DIAGNOSTIC: added the description of the unit of measurement used in the vertical vibration scale
• DIAGNOSTIC: In the “Recorded Logs” tab, changed the cursor from a vertical line to a cross to be able to intercept the lateral scale values
• DIAGNOTIC: renamed “RxAux1 %” to “RxB-Aux1 %”, “RxAux2 %” to « RxB-Aux2 %”, “RxAux3 %” to “RxB-Aux3 %”

Crashes all the time

The app is good, however you can not use it as it crashes all the time. Don’t try to update using the app otherwise you will kill the unit. The log also does not work well. If they fix the bugs, it will be great.


Works well.

The app works well. When I first used it it would constantly crash, but with the current version it have been very nice to have.

The app works great. Can’t beat it for making changes at the field or doing firmware updates at home.
