you also need this:

at!band=9
AT!reset

62

AT!band=9,1,“groupo”,1, 0000000000000000,0000000000000004

results in ERROR

63

how about

AT!band=13,1,“groupo”,1, 0000000000000004,0000000000000000

64

yes that worked - isnt that setting the GSM mask tho?

65

did you check AT command user guide?

66

I think I see… the 1 after groupo means those masks are for LTE?

67

yeah - i got it now :smiley:

AT!band?
Index, Name
13, groupo,
0 - GW: 0000000000000000
1 - LTE: 0000000000000004 0000000000000000
3 - NRNSA: 0000000000000000 0000000000000000
4 - NRSA: 0000000000000000 0000000000000000

AT!LTEINFO?
!LTEINFO: Unavailable

OK

68

how about AT!GSTATUS? now?
Did you set the APN correctly in AT+CGDCONT?

69

No I forgot to set APN, I usually do it via a drone program not with AT commands. Looks like the syntax is

AT+CDGCONT=1,“IP”,“lte” ?

70

AT+cgdcont=1,“IP”,“lte”
OK

AT+cgdcont?
+CGDCONT: 1,“IP”,“lte”,“0.0.0.0”,0,0,0,0,“”,0
+CGDCONT: 2,“IPV4V6”,“ims”,“0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0”,0,0,0,0,“”,0

OK

AT!gstatus?

71

it says there is no such band

72

what does that mean? The network doesnt exist on that band? I have extensive diagnostic info about the network if that will help you

I dont see “no band” in the documentation for !lteinfo

73

i have no idea then, you need to find distributor for help

74

my phone says “LTE FDD 1800 band 3”, does that help you?

75

I get this now too

AT+COPS=?
+CME ERROR: operation not allowed

76

I think distributor can help you

77

distributor of what? the network?

78

distributor of EM9291 module

79

do you know what is causing the +CME error?

80

Do you see this error when setting at!band=0?
