I am using the sample code provided for the latest Arduino OPCUA library.
It loaded and connected to a 3rd party Integration Objects OPCUA client. I can easily load tags and monitor them. However the current Server configuration has a security mode as None, Security Policy as None and User Authentication Mode as Anonymous. That completely nullifies the whole purpose of the UA part of OPC. There is no documentation defining how to set up the OPCUA configuration within the github site-- GitHub - arduino-libraries/Arduino_OPC_UA. I decided that all of the configuration must be done within the Open62541 API and classes. So I tried entering these documented Open62541 configuration settings.
` /* Create a server listening on port 4840 (default) */`
`opc_ua_server = UA_Server_new();`
`/* Configure server with default settings */`
`UA_ServerConfig *config = UA_Server_getConfig(opc_ua_server);`
`UA_ServerConfig_setDefaultWithSecurityPolicies(config, 4840, NULL);`
`UA_ServerConfig_addSecurityPolicyBasic128Rsa15(config, UA_MessageSecurityMode_Sign, NULL, NULL);`
This did not work. So any ideas on changing the server configuration within Arduino OPCUA for OPTA?
