I'm working on the Apache PLC4X project where we implement industry PLC protocols using Netty. We are currently encountering a problem with decoding responses as soon as the size of these exceed a limit of 512 bytes.
As soon as the size of the response exceeds these 512 bytes, the decode method of our MessageToMessageCodec based protocol layer implementation only receives a 512 byte large ByteBuf. Directly after this, the method is called again with the rest of the packet.
How would be the correct way to handle this?
