S.BUS vs PPM / RFD telemetry quality

Hello to all!

First I will start with questions, below is the description of my problem:

  1. Does S.BUS load the connection more than PPM?
  2. Can the yaapu script in TX16S display telemetry using mavlink transmission or does it only receive data from S.BUS?

For a few years I have been using brilliant RFD radio modems without any problems (mavlink telemetry + ppm), but a few days ago I decided to buy RFD TXMOD v2 and TX16S MK2 radio, because my dream was to have basic telemetry data on the radio. From what I understood, in order to get telemetry via yaapu script, I have to set RC connection to S.BUS instead of PPM. This caused a terrible slowdown in telemetry data via wifi (I have not managed to start via yaapu yet - but I do not know whether to bother with it if S.BUS loads the connection more). My priority is smooth transmission of telemetry, I have never had a problem with the PPM signal. I can’t increase the air speed to more than 64kbps. Before I started testing it, I was sure that the TX16S would simply receive telemetry from the RX/TX modem.

I searched the whole forum, including a great thread Combined RC and Telemetry on a single link (TXMod v2, RFD 900x, TX16S, GCS, Matek H743) - #39 by atex
where @xfacta explained the topic in detail, but I’m afraid of slowing down the transmission to use telemetry in the TX16S via S.BUS.

I would be very grateful for your help :slight_smile:
