Check for cellular registration and connection

The cellular network registration and address assignment must occur successfully. To verify the network connection, you can view the LED on the development board or check the status of the relevant commands in XCTU.

Registration typically takes 5 - 6 minutes the first time a device is connected to the network.

Before you begin

A working SIM card is required. See Determine cellular service and acquire a SIM card.
Make sure you have added the device to XCTU. See Add a device to XCTU.
Make sure you are in an area with adequate cellular network reception.
Verify that the antennas are connected properly to the device.

View LED action

The LED on the development board blinks when the XBee is registered to the cellular network; see Associate LED functionality. If the LED remains solid, registration has not occurred properly.

View commands in XCTU

Launch XCTU .
Click the Configuration working mode button.
Select a device from the Radio Modules list. XCTU displays the current firmware settings for that device.
Verify the status of your network connection using the following commands:
- AI (Association Indication) reads 0 when the device successfully registers to the cellular network and the LED is blinking. If it reads 23 it is connecting to the Internet; 22 means it is registering to the cellular network.
- MY (Module IP Address) should display a valid IP address. If it reads 0.0.0.0, it has not registered yet.
