Post by amy123 on codesys mqtt publish serialization ^{CODESYS Forge talk (Post)}
Hello, I am using the CODESYS IIoT Libraries SL MQTT Publish. Does this publish block only support publishing STRINGS as a readable format? I can publish ENUM, STRUCT, BOOL; however, MQTT Explorer will only display strings. When I use Wireshark, I can see that it is publishing something, but it looks to be publishing a serialized version which is a bunch of 0s or random text. If so, is there any way to deserialize this information back into a readable format? See pictures, where I have a BOOL TRUE that gets published as 001. Then see where I publish a STRUCT and it's an incomprehensible combination of 0s - only the string variable is displayed. Or, is it expected that you convert everything to a string before publishing? Any help is greatly appreciated! :)
