Packager buffer overflow for vectors sized above 3

[pierrebarroca]

When I try to add a vector with size above 3 the package buffer overflows.

Below the error log on dymola

dymosim started ... "dsin.txt" loading (dymosim input file) MDDUDPSocket.h: Opened socket for sending. MDDUDPSocket.h: Waiting for data on port 10002. The following error was detected at time: 0 MDDSerialPackager.h: MDD_SerialPackagerAddDoubleAsFloat failed. Buffer overflow.

The stack of functions is: ModelicaDeviceDrivers.Packaging.SerialPackager.addRealAsFloat Modelica_DeviceDrivers.Blocks.Packaging.SerialPackager.Internal.DummyFunctions.addRealAsFloat

Does it help if you increase the buffer size or utilize the automatic buffer size propagation feature in packager block and sender/receiver block?

[pierrebarroca]

I tried with autoBufferSize checked and also changing userBufferSize. You can trigger the same error with the TestSerialPackager_UDP example in the library by changing the size of the vector inputs for addReal and addFloat blocks.

The addReal block raises error for vectors with size above 3 and the addFloat for vector sizes above 2.

Did you adapt the settings in all three blocks: sender, receiver and packager block?

I solved the problem. Indeed, I was adapting all the settings settings only on the sender and receiver and not in the packager block. Thank you @tbeu !
