For my tests, running the latest beta firmware (shown below) I got no problems; all AT commands display correct info:
Current Firmware
Version 4.0
Firmware Type release10301
Compile Time 2023-05-12
AT+QCAINFO
+QCAINFO: “PCC”,1650,100,“LTE BAND 3”,1,264,-68,-13,-31,10

OK

+QENG: “LTE”,“FDD”,420,04,3502100,264,1650,3,5,5,D2,-68,-12,-36,13,15,-40,-
+QENG: “NR5G-NSA”,420,04,916,-71,30,-11,528990,41,11,1
OK
However when clicking “Export Debug Info” function, there are some unsupported commands by Quectel modem:
"msgs": [
{
"cmd": "AT",
"result": "AT\r\r\nOK\r\n"
},
{
"cmd": "ATI",
"result": "ATI\r\r\nQuectel\r\nRM520N-GL\r\nRevision: RM520NGLAAR01A07M4G\r\n\r\nOK\r\n"
},
{
"cmd": "AT+GMI",
"result": "AT+GMI\r\r\nQuectel\r\n\r\nOK\r\n"
},
truncated ............................................
{
"cmd": "AT+QCFG=\"nwscanmode\"",
"result": "AT+QCFG=\"nwscanmode\"\r\r\nERROR\r\n"
},
{
"cmd": "AT+QCFG=\"band\"",
"result": "AT+QCFG=\"band\"\r\r\nERROR\r\n"
}
I believe these commands should be replaced in the next firmware release with the equivalent ones as they are no supported anymore
