<![CDATA[Quectel RM502Q-AE support for LTE bands]]>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

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

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
