Open LTE LinkMonitor API to any nrf9160 board and firmware stack

Hello,

we are using the nRF9160 on our own hardware and freeRTOS.

Since our toolchain & firmware stack is not using any zephyr code it would be nice to have to API of your LTE Link monitor documented and let the nrfConnect LinkMonitor app also connect to any of the present COM ports on the PC. Would this be possible in the near future?

Greetings

  • Hi Theo,

    1. Please deselect "Auto device/port filter":

    Then you will get the option to select the COM ports present on the PC:

    2. The LTE Link Monitor only send AT commands as strings to the nrf9160 and read out the responses.

    When the "Automatic requests" in settings are checked the LTE Link Monitor application will run through a script sending the strings:

    AT+CFUN=1
    AT+CFUN?
    AT+CGSN=1
    AT+CGMI
    AT+CGMM
    AT+CGMR
    AT+CEMODE?
    AT%XCBAND=?
    AT+CMEE?
    AT+CMEE=1
    AT+CNEC?
    AT+CNEC=24
    AT+CGEREP?
    AT+CGDCONT?
    AT+CGACT?
    AT+CGEREP=1
    AT+CIND=1,1,1
    AT+CEREG=2
    AT+CEREG?
    AT%CESQ=1
    AT+CESQ
    AT%XSIM=1
    AT%XSIM?
    AT+CPIN?
    AT+CPINR="SIM PIN"
    AT+CIMI

    and the application running on the nrf9160 uses the at_host library receives these strings and serializes between the modem and the PC.

    best Regards,
