    Is there any way to get clock info from AT interface?

    I’m using xDot/mDot modules and I’m expecting they are synchronized by the LoRaWAN Network (as specified in LoRaWAN Application Layer Clock Synchronization Specification v1.0.0). Isn’t it?

    Now… I’d like to get the date information at application level, in order to synchronize my application behavior.

    Is it possibile? any suggestion how to do that?

    Thanks,
    Luca

    The App Layer clock sync is not implemented.

    Following the protocol in the specification will allow you to get the date information at the application level through the network server.

    Thanks Jason.
    I try to repeat what I understood, just to check my comprehension:
    – Multitech doesn’t implement The App Layer clock sync at Network Server side (inside the GW I suppose)
    – The FW of mDOT/xDOT is not compliant with LoRaWAN 1.1 so it doesn’t implement DeviceTimeReq MAC command
    – You suggest to implement this service at application level, above xDOT/mDOT AT firmware and above LoRaWAN Network Server

    Can you confirm my understanding?

    Thanks,
    Luca

    Yes, that is the intent of the LoRaWAN Application Layer Clock Synchronization Specification v1.0.0.

    We have not released xDot/mDot with LW 1.0.3 or LW 1.1 support with DeviceTimeReq/Ans.

    Is it LW 1.03 or LW 1.1 support in roadmap?
    More or less… do you know when they should be available?

    Thanks,

    LW 1.0.3 should be available this year and LW 1.1 next year.

    When the LW 1.1 will be available on xDot/mDot side, how can I figure out to get the time/date at application level?

    I immagine to operate with a Network server compliant with LW 1.1.
    In this case, can I suppose to have new AT commands to get date&time from the module?

    What about the accuracy that can I expect?

    Thanks,
    Luca

    Is there anybody can answer to my question above?
    Can you give me also a more accurate expected date for the LW 1.1 availability next year?

    Thanks a lot,
    Luca
