Description
We coded a small app to test some Modbus devices, it works without any problem in 5.13.0, but when I try to compile and run the same code in 5.13.1 it stops working.
When I send a request I do not get any errors, replies, and no timeouts.
The first request goes out, and the modbus device does what is should do, but after that I get no reply objects finished signal, and any other request will not go out, the rtu master only sits there and does nothing. When I disconnect it, it only writes out a
qt.modbus.lowlevel: (RTU client) Aborted replies: 6
debug text.
I also tried it with the Qt Modbus Rtu Master example, and the same thing happens, it works in 5.13.0, but not in 5.13.1.
