General getting started information

Please refer to the main Knowlegdebase page for modem-independent configuration tips.


BG96 NB-IoT

Initialization

KORE Narrowband can be made accessible by setting iotopmode to 1: AT+QCFG="iotopmode",1,1.

Operator selection

Calling AT+COPS redundantly can adversely affect connection times. We recommend using automatic operator selection: AT+COPS=0.

Low-power modes

While the BG96 supports low-power modes for eDRX and PSM, support for these features will vary by visited network and location. The commands for each of these settings are:

  • eDRX: AT+CEDRXS

  • PSM: AT+CPSMS

Known issues

1. DNS servers may not be provided by the network with the Twilio Narrowband SIM

Modem firmware versions prior to BG96MAR03A06M1G may not receive valid DNS servers upon connection. Affected versions include, but are not limited to, BG96MAR02A06M1G and BG96MAR02A07M1G.

This issue does not impact GSM connections maintained by the Narrowband SIM.

This issue can be observed by connecting to the network and executing the following commands, noting the 0.0.0.0 DNS addresses:

AT+QICSGP=1,1,"iot.nb"
OK
AT+QIACT=1
OK
AT+QIACT?
+QIACT: 1,1,1,"x.x.x.x"
OK
AT+QIDNSCFG=1
+QIDNSCFG: 1,"0.0.0.0","0.0.0.0"
OK

Attempts to resolve a host name to an address will fail:

AT+QIDNSGIP=1,"www.twilio.com"
OK

+QIURC: "dnsgip",565

Recommended solution Update the BG96's firmware to version BG96MAR03A06M1G or above.

Workaround Provide DNS servers manually after connection with the following command:

AT+QIDNSCFG=1,"8.8.8.8","8.8.4.4"

This example uses Google's DNS servers, but you can use the DNS service of your choice.
