By following this B4J Code Snippet and sample project how-to-connect-to-a-mqtt-broker-that-requires-a-client-certificate I have been able to successfully connect to my MQTT broker when run B4J in Debug or Release compilation modes. The code snippet works very well and I only needed to add my three certificate details and the MQTT broker URL to make it work.
However despite many attempts, I am unable to get it to connect when I use the built-in packager to build a standalone executable.
If have tried adding:
However when I build try to build and a standalone executable, the sample project crashes. When I run Run_debug.bat, I see the following debug information:
I suspect there may be a #PackageProperty I am missing, but I really am not sure what to do from here.
