Falco,
I capped my OpenTx at version 2.3.14 as everything I needed worked well with that release. Before that when OpenTx 2.3.9 was out, Jim Drew made an accommodation in the XPS-J1 module code to work around a bug in the OpenTx XJT-16 implementation. OpenTx later fixed their problem with OpenTx version 2.3.10. I finally upgraded to OpenTx 2.3.14 because it fixed a problem where the little lithium battery in the transmitter that saves the memory was being depleted too quickly.
So, now I'm sitting at OpenTx 2.3.14 for a couple of years without any troubles with the XPS-J1 module.
It is possible that EdgeTx introduced some new bug in their XJT-D16 implementation that is causing your problem.
