Learn how to attach BC66-T-BE DVK from Quectel to NB-IoT network

This chapter explains how you can attach the BC66-T-BE DVK to the NB-IoT network. I recommend to read the chapter "Setup Quectel BC66-T-BE DVK" first.

🚧

If you are only interested in the conclusion of the AT commands to configure the network setup go to chapter "'AT Setup Commands" end of this document.

📘

In case you are looking for any documentation documents goto the setup chapter of the device.

After you switched on the device and deactivated the auto-sleep (AT+QSCLK=0) and activated the echo of inputs (ATE1) you can configure the network setup for the module with the following steps:

Set mobile operation band: AT+QBAND=1,8

AT+QBAND=1,8
OK

Swicht off radio functionality: AT+CFUN=0

AT+CFUN=0
OK

Setup the default APN: AT+QCGDEFCONT="IP","APN-Address""

AT+QCGDEFCONT="IP","cdp.iot.t-mobile.nl"
AT+QCGDEFCONT="IP","iot.telekom.net"
AT+QCGDEFCONT="IP","iot.1nce.net"

Restart device after network setup
Some configurations of the network setup take only effect after the device has been restarted.

Restart device: AT+QRST=1

AT+QRST=1 
F1: 0000 0000
V0: 0000 0000 [0001]
00: 0006 000C
01: 0000 0000
U0: 0000 0001 [0000]
T0: 0000 00B4
Leaving the BROM

Don't forget to disable auto-sleep and enable echo of inputs:

AT+QSCLK=0
OK

ATE1
OK

If everything works fine you shoul get displayed after 10-45 seconds the IP address which the device gets assigned by the network

+IP: 10.0.0.239

👍

Yeah!! If you see the IP address on the console after starting up the device you did everything perfect and your are ready now to send and receive data.

In case of an failure and the device doesn't get an IP address the problem can be fixed sometimes by defining local operator explicity.

Configure operator manually: AT+COPS=1,2,"26201"

AT+COPS=1,2,"26201"
AT+COPS=1,2,"20416"
AT+COPS=1,2,"23203"
