I have this function which handles connections to multiple barcode scanners. I noticed that the onError and onClose events are not getting triggered, even when disconnecting the scanners.

Where can I find the socket class to inspect it? In Simplifier’s ‘Code’ section I can only find the js files for websocket, but not for socket.

I am relatively sure that these events still worked under Simplifier 8. Was there a change here in Simplifier 9?

 

function fxConnectSocket(sUrl, sVarName, fxOnData = () => {}) {
let socket = new Socket();
const aParts = sUrl.split(‘:’);
const iId = Math.floor((1 + Math.random()) * 0x10000).toString(16).substring(1);
const handleConnection = (status) => {
sap.ui.getCore().getModel(‘variableHolder’).setProperty(/${sVarName}, status);
};
const reconnect = () => {
console.log(Socket ${iId} of type ${sVarName} connection to ${sUrl} closed. Reconnecting in 1 second...);
setTimeout(() => socket = fxConnectSocket(sUrl, sVarName, fxOnData), 1000);
};
socket.open(aParts[0], parseInt(aParts[1]), () => {
handleConnection(‘Connected’);
console.log(Socket ${iId} of type ${sVarName} connection to ${sUrl} opened.);
}, (event) => {
handleConnection(‘Disconnected’);
console.log(Socket ${iId} of type ${sVarName} connection to ${sUrl} failed with code ${JSON.stringify(event)}.);
// reconnect();
});

socket.onData = fxOnData;

socket.onError = function(event) {
handleConnection(‘Disconnected’);
console.error(Socket ${iId} of type ${sVarName} had an error:, JSON.stringify(event))

reconnect();
};
socket.onClose = function(event) {
handleConnection(‘Disconnected’);
console.log(Socket ${iId} of type ${sVarName} connection to ${sUrl} closed because of error ${JSON.stringify(event)}.);
reconnect();
};

return socket;
}

Hi Deniz,

 

You can find the code for the sockets in our GitHub repository. This plugin is included in the mobile Client.

I don’t think there was a change in the Sockets code in recent times, so it should not be related to the update.

I hope this helps you out in identifying your issue.
