Problems with network connection
-
I cannot connect to the radio network. Is there an AT command sequence starting from initializing the modem till attachment to the network ?

Updated AT command sequence. The following commands need to be executed as displayed here:
// Turn Off Radio (IMPORTANT)
AT+CFUN=0
// The following commands need to be executed only once
AT+QCFG=“nbsibscramble“,0
AT+CPSMS=0,“00000001”,“00000001”
// !-> Reboot and turn off Radio (AT+CFUN=0)!
AT+QCFG=“band“,0,0,80,1
AT+QCFG=“nwscanmode“,3
AT+QCFG=“nwscanseq“,030201
AT+QCFG=“iotopmode“,1
AT+QCFG=“servicedomain“,1,1
AT+QCFG=“gprsattach“,0
// Turn on Radio
AT+CFUN = 1
// APN
AT+CGDCONT=1,“IP”,“internet.nbiot.telekom.de”
AT+COPS=?
AT+COPS=1,2,“26201“,9
// Check if modem is attached
AT+CGATT?
// Check if modem is registered correctly. Expected result is : +CEREG: 0,5
AT+CEREG?

What is the CGDCONT for the US? Is any thing else different for the US?

Dear Pete,
thank you for your question. It will be answered soon. -

The command for the US is:
AT+CGDCONT=1,“IP”, “iot.nb”
