[REG 5.13.0->5.13.1]: Modbus RTU Serial Master No Response and No Timeout error

    XMLWordPrintable

    Details

    • Platform/s:
      Windows

      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.
