Get command is appended always to long keep-alive command and never to short keep-alive. * Device sends multiple get commands appended to the 1st uplink. * Device now can operate with both unconfirmed and confirmed uplinks. By default unconfirmed are used. Since some device events still require confirmation from the server (flood or fraud detection), it sends those with confirmed uplinks. Otherwise long keep-alive message with the related reason will be invoked up to 8 times by the device. ### Firmware version 1.5 **Release date:** \ 11 May 2021 * Bug fixed at LoRaWAN MAC Layer ### Firmware version 1.4 **Release date:** \ 20 April 2021 * Add a command for device deactivation (0x0B) * Improve the button press detection logic to handle more than one pressed button at a time ### Firmware version 1.3 **Release date:** \ 1 Jan 2021 * Introduction of new, better optimized firmware libraries * DevEUI, AppEUI, AppKey are not configurable via UART ### Firmware version 1.2 **Release date:** \ 31 July 2020 * Bug fix related to power consumption. ### Firmware version 1.1 **Release date:** \ 22 July 2020 * Initial firmware release --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.mclimate.eu/mclimate-lorawan-devices/devices/mclimate-t-valve-lorawan/release-notes.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
