New API - EMA - error “connection type disallowed,”

adam_saye1

Hi All,

A new API EMA has been created but the team are receiving a “connection type disallowed” log output msg in the ADS log. Websockets / 15000. The DACS id has been successfully tested in the DACS GUI.

Any ideas?

Many Thanks

Thank you for reaching out to us.

I assume that you are using an incorrect connection type when establish a connection to ADS.

When using a Websocket connection to ADS, the EMA configuration should look like this:

		<Channel>
			<Name value="Channel_6"/>
			<ChannelType value="ChannelType::RSSL_WEBSOCKET"/>
			<CompressionType value="CompressionType::None"/>
			<GuaranteedOutputBuffers value="5000"/>
			<Host value="192.168.42.195"/>
			<Port value="15000"/>
			<WsMaxMsgSize value="61440"/>
			<WsProtocols value="rssl.json.v2, rssl.rwf, tr_json2"/>
		</Channel>

The ChannelType must be ChannelType::RSSL_WEBSOCKET and the consumer must be configured to use this channel.

		<Consumer>
			<!-- Name is mandatory -->
			<Name value="Consumer_6"/>
			<Channel value="Channel_6"/>
			<!-- Dictionary is optional: defaulted to "ChannelDictionary" -->
			<Dictionary value="Dictionary_2"/>
			<XmlTraceToStdout value="0"/>
			<DefaultServiceID value="1"/>
		</Consumer>

If this doesn't solve the issue, please let us know the EMA version (C++, Java, or CSharp) and version number used by the application. Moreover, please share the EMA configurations used by the applicaiton.
