    Below mwf_nrf9160_1.3.2 version showing in link_monitor why mwf_nrf9160_1.3.4 version device not showing in link_mother?

    at_client shall work with both of these mfw versions.

    Can you share any logs or similar? Have you tried reprogramming the device in-question?

     

    Kind regards,

    to see logs first it have to show the device port but its not showing  port in lte_link_monitor.

    but when use  mwf_nrf9160_1.3.2  it showng device port But when i use mwf_nrf9160_1.3.4   its not even showing the device port.

    Thanks

    What do you mean specifically with "device port" ? Do you mean the USB-uart adapter?

    If yes; this is a external component and should not have any effect on the nRF9160 at all.

     

    Can you share screenshots or logs of what your issue is?

     

    Kind regards,

    In this screenshot you have seen  usb0 port in arduino. but its not showing in lte_link_monitor 

    in my device that usb is going to act like a uart0

    Hi,

     

    Thank you for sharing this.

    You can use any terminal you'd like to send AT commands.

    For other ports to be detected in LTE Link Monitor, you have to ensure that the "Show only supported devices" is left unchecked:

    Then it should appear in the list:

     

    Kind regards,

    Håkon
