    Hello guys,

    I tried to send a couple of AT commands to xDot EU868 module (xdot-firmware-3.0.0-EU868-mbed-os-5.4.7.bin firmware), for example AT+NSK, AT+DSK, or AT&V. But the module did not respond. While on others, AT+NA, AT+NJM the module responded.

    Any of your suggestions, thoughts.

    Thanks for the support / help.

    What output do you get?
    How is the module connected?

    I get nothing. Connected via UART.
    By the way, I have two set of models xDot MTXDOT-EU1 (EU868) and xDot MTXDOT-NA1 (US915). With US915 Model I have no problems with interaction.

    You get nothing every time you try AT&V?
    But AT+NA is always successful?

    How about ATI?

    It sounds like a connection issue.

    There are firmware updates available:

    Exactly, AT&V no reply every time.
    For ATI I get:
    MultiTech xDot
    Firmware : 3.0.0-rc7-mbed144
    Library : 3.0.0-mbed144
    MTS-Lora : 3.0.0
    OK

    3.0.0-rc7 looks suspicious.

    Try the 3.0.0 firmware from downloads or update to 3.1.x or 3.2.1

    Thanks Jason,
    I will try the new firmware and give you know the results.
