Hi,
I have CHINA TELECOM and CHINA UNICOM sim card. When I test with bg77, I can’t join to NBIOT. Below is my log, After set to NB search mode, AT+COPS=? will never return any response over 1 min. What is the problem?
[10:30:23.097]收←◆
RDY
AT+QCFG=“nwscanseq”,03
OK
[10:30:25.148]收←◆
APP RDY
AT+QCFG=“iotopmode”,1
OK
[10:30:27.199]收←◆AT+QCFG=“band”,F,2000095,2000095
OK
[10:31:27.786]收←◆AT+COPS=?
And if join ok, can I use AT+QPING=1,“www.baidu.com” directly? Or need any other set?
AT+QCFG=“NWSCANSEQ”,03,1 // config to search NB network first
AT+QCFG=“nwscanmode”,3,1 //LTE ONLY
AT+QCFG=“iotopmode”,1,1 //LTE Cat.NB1 only
AT+CFUN=0
AT+CFUN=1
For the AT+COPS=?,the module will search for available networks around and looks like “blocked” until the search is completed.
Note: It will clear the previous network configuration, such as AT+COPS=? and AT + COPS = XX but AT + COPS? will not be.
