Hi,
I am searching for an Android App that can handle the S.Port Passthrough data from Ardupilot (I am interested in the text messages, therefore non-passthrough Frsky-telemetry is not an option). I find a lot of Apps, that can handle plain mavlink data, but I do not use any external telemetryradio. I can interface the telemety stream from my FrSky module to my phone via usb- or bluetooth-serial. I use a rc-radio which can not handle the lua apps available.
An arduino program, that displays everything on an oled or lcd screen would also be an option.
Some way of displaying the Frsky Passthrough Telemetry (not regular FrSky Telemtry). Either with an app on my phone, or a Passthrough-to-Mavlink converter (Mavlink data can be displayed by multiple apps). The difference between the normal and passthrough telemetry is, that passthrough also sends the textmessages from the FC. The app you suggest only seems to be able to display normal Frsky Telemetry, but correct me, if I am wrong
