After you have setup your devkit successfully you learn in this chapter how you can attach your device with the NB-IoT network.
The basic NB-IoT configuration parameter which you need during your journey through the network attach you can find on the page IoT Configuration Parameter
Good Luck !!
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 scroll to the end of this document under the header "AT Commands to setup Network Configuration".
In case you are looking for any documentation documents go to 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:
Restart device after network setup
Some configurations of the network setup will only take effect after the device has been restarted.
AT+QRST=1 F1: 0000 0000 V0: 0000 0000  00: 0006 000C 01: 0000 0000 U0: 0000 0001  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 you should get an IP address displayed after 10-45 seconds which the device has been assigned by the network.
Yeah!! If you can see the IP address on the console after starting up the device you did everything perfect and your are now ready to send and receive data.
If that is not the case and the device doesn't get an IP address the problem can be fixed sometimes by defining local operator explicity.
