I’ve just wired up the RFD 868+ and TXMOD V2 with Pixhawk 2.1, all is working well so far but I got couple questions regarding this system.
What are all those telemetry pins, why do I need 4 of them ? I mean there is: CTS (TX), RTS (RX), TX and RX + RCin on servo rail. Can somebody explain what is going on on all those pins and why do I need 4 ? Normally, I’d expect only transmitting and receiving pin for telemetry + RCin.
Is there any other way to use PPM for RC control, than plugging in pin 15 to RCin port on servo rail ? Isn’t it possible to send RC control link PPM via telemetry port to control the aircraft straight from the Taranis ?
Is there any other way for displaying telemetry data on Taranis X9D+ apart from Yaapu script ? It was possible with crossfire, but Taranis wont discover any sensors with RFD900.
