2 27-Jan-2021, 09:58 PM (This post was last modified: 27-Jan-2021, 10:24 PM by coyote_dc5.) So one of my quads uses ESC sensing over a separate wire and another does not. Both run 8k/4k bidirectional dshot600 with gyro RPM filters so my question is what the advantage over doing full telemetry over a separate wire vs just the standard PWM wires from each ESC?
I assume its something to do with speed and reducing the chances of desyncs?

103 bidirectional dshot does provide a sort of telemetry without an additional cable.
rpm filter does need bidirectional dshot, the esc telemetry you mention wont work with bf filtering.
i dont use esc telemetry, someone else shiuld answer this question xD i see no need

796 ESC telemetry (only available on BLHeli_32 ESCs) is quite useless in my experience unless you want to clutter your OSD with a load of extra items. It provides RPM values of each motor, current being drawn by each motor (only if the ESC has separate shunt resistors for each ESC), and temperature of each ESCs. I found it to be a gimmick and don't use it. I just use the analogue current sensing which gives a total current for all ESCs and I don't care for the RPM or temperature values of each motor in my OSD.
