How do I know the exact version on my modem. when i send “ATI”, I just get generic model name and revision

Quectel
RM520N-GL
Revision: RM520NGLAAR01A07M4G

I’d like to know if it’s a custom version like RM520N-GLAAP or similar.

When I open a connection with modem throught “picocom /dev/ttyUSB2”, the modem starts automatically to send informations in a loop sequence. How do I stop the loop?

thanks

Thanks for the documents. They are very detailed. But unfortunatelly I don’t find any comparation about Carrier Aggregation between GLobal and EUropean versions.

Could you kindky tell me if my RM520N-GL (Revision: RM520NGLAAR01A07M4G) can perform same total aggregation of carriers in Italy (Europe) as the RM520N-EU?

I tryed to customize aggregation:
AT+QNWPREFCFG= “lte_band”,1:3:7:20:28:38 (Set LTE n 1, 3, 7, 20, 28, 38)
AT+QNWPREFCFG= “nsa_nr5g_band”,3:28:78 (Set NR5G NSA 3, 28, 78)
AT+QNWPREFCFG= “nr5g_band”,3 (Set NR5G SA n3)
OK

But I just get this result:
+QCAINFO: “PCC”,100,100,“LTE BAND 1”,1,201,-81,-9,-52,3
+QCAINFO: “SCC”,1500,50,“LTE BAND 3”,1,201,-79,-13,-56,0,0,-,-
+QCAINFO: “SCC”,2900,50,“LTE BAND 7”,1,20,-84,-10,-64,0,0,-,-
+QCAINFO: “SCC”,3350,100,“LTE BAND 7”,1,20,-86,-12,-66,0,0,-,-
+QCAINFO: “SCC”,1650,100,“LTE BAND 3”,1,201,-78,-13,-55,0,0,-,-

Last question:
There any chance to flash the RM520N-GL version with RM520N-EU firmware?

thanks
