"powerdownnow" – turn off modem immediately without waiting for pending actions to complete "startlwm2m" – start the LwM2M protocol "startmqtt" – start AnyNet Secure MQTT application "startudp" – start UDP telemetry application "stop" – stop AnyNet Secure MQTT, LwM2M, or UDP telemetry application. Use this to cleanly shutdown before power off. | OK After AT+ETMSTATE="stop", AnyNet SMARTconnect™ returns to idle and the following response occurs: +ETM: IDLE or +ERROR: | #### Example ``` AT+ETMSTATE? +ETMSTATE: 0 OK ``` --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://docs.eseye.com/smartconnect/at-command-reference/management-at-commands/etmstate-check-current-state.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
