Device does not wait for a response even specifying hono-ttd=60

[Lando-Ant]

I am using Eclipse Hono and I am experiencing an issue with hono-ttd, that is, when I launch the HTTP POST command from the device to send telemetry data by specifying e.g. hono-ttd=60, the device does not wait to receive a command instead it continues its execution. Moreover, I have no idea where to found the hono-cmd-req-id that should be returned by the device receiving the command.

This is the command I used to send telemetry data from the device: curl -i -u [email protected]:demo-secret -H 'application/json' --data-binary '{ "topic": "org.eclipse.packages.c2e/demo-device/things/twin/commands/modify", "headers": {}, "path": "/features/temperature/properties/value", "value": 45 }' http://${HTTP_ADAPTER_IP}:${HTTP_ADAPTER_PORT_HTTP}/telemetry?hono-ttd=60 After sending the above telemetry data, I expect the device to wait for a command. Instead, the device does not wait and immediately returns: HTTP/1.1 200 OK hono-command: modify-response content-type: application/vnd.eclipse.ditto+json content-length: 361

Thanks in advance for helping out!
