Hi,

Sim: Vodafone Italy enabled for NB-IOT.

This is the procedure I follow:

AT+QSCLK=0
ATE1
AT+CSCON=1
AT+QBAND=1,20
AT+CFUN=0
AT+QCGDEFCONT="IP","m2m.vodafone.it"
AT+QRST=1
AT+QSCLK=0
ATE1
AT+CSCON=1

This is the result:

F1: 0000 0000

V0: 0000 0000 [0001]

00: 0006 000C

01: 0000 0000

U0: 0000 0001 [0000]

T0: 0000 00B4

Leaving the BROM

As you can see it keep getting denied.
If I put the sim in a phone it works with the apn “m2m.vodafone.it” so I don’t know what to try.

Hi!

I have an Olimex BC66 DevKit.

I have sent the following commands:

ATE1

Quectel_Ltd
Quectel_BC66
Revision: BC66NBR01A10
OK

AT+QCCID
+QCCID: 8939104590000783742F

AT+CGSN=0

AT+CPSMS=0

AT+QSCLK=0

AT+CEREG=5

AT+CSCON=1

OK

AT+QBAND=1,8
OK

AT+QCGDEFCONT="IP"," m2m.vodafone.it" [APN Given to me]
OK

AT+CGPADDR=1

and these are the results:

CEREG: 0,,,,,0,0

CEREG: 2,,,,,0,0

AT+CEREG?
CEREG: 5,0,,,,,0,0

AT+CEREG?
+CEREG: 5,0,,,,,0,0
OK

+CEREG: 2,,,,,0,0

+CEREG: 0,,,,,0,0

Looks like the registration didn’t happen successfully. What could be the problem? Maybe a command? Maybe the APN? Any hint?
