    HI , I have a general question. Our Modal AI VOXL2 has a Quectel RM502Q-AE . Does it only support 5G SA & NSA or can the device connect to LTE band ( B4 for example) ? I noticed that Quectel AT command provides option for both 4G/5G mode preference and datasheet suggested it supports LTE band

    echo -ne "AT+QNWPREFCFG="mode_pref",LTE:NR5G\r" | busybox microcom /dev/ttyUSB2

        That's what my understanding is too based on the datasheet. But how do I make the quectel modem only look for LTE . I used below command to set LTE only mode but it didn't work

        echo -ne "AT+QNWPREFCFG="mode_pref",LTE\r" | busybox microcom /dev/ttyUSB2

        Is there any internal configuration or config file that is overriding user command

          @IFTEKHAR-HASAN I also updated the AT command on voxl-modem-start.sh to connect to LTE but I am getting error with AT command as seen in "systemctl status voxl-modem"

          Can you let me know if you see any issue here . or does the AT command has any issue?

            @IFTEKHAR-HASAN I have used this AT command at!selrat=06 to force only LTE mode on a Sierra cellular modem in the past.
