I'll recheck wiring tomorrow, but pretty sure it wouldn't work on OTX if it was a hardware issue. I happen to have an oscilloscope, but no serial analizer. What should...

I did a few measurements. If by pin1 you mean the top pin, then there is a signal on that one. (running OTX or EdgeTX) It does not look clean...

pin5 (the bottom one right under GND) looks like this: 

well, it's a very basic and cheap scope... Why does it work on OpenTX though?

 Connections look ok to me, but there is definitely a hardware issue here. When i connect the probe to pin1, the module loses telemetry even on OpenTX. Now i...

BTW just came back from the field where i had 2 flights on OpenTX. Not a single glitch,
