Check for cellular registration and connection
In the following examples, proper cellular network registration and address assignment must occur
successfully. The LED on the development board blinks when the XBee Smart Modem is registered to
the cellular network; see The Associate LED. If the LEDremains solid, registration has not occurred
properly.
Registration typically takes 5 - 6 minutes the first time a device is connected to the network.
Note Make sure you are in an area with adequate cellular network reception or the XBee Smart
Modem will not make the connection.
Note Check the antenna connections if the device has trouble connecting to the network.
In addition to the LED confirmation, you can check the AT commands below in XCTU to check the
registration and connection. To view these commands:
1. Open XCTU and Add a device.
2.
Click the Configuration working mode button.
3. Select a device from the Radio Modules list. XCTU displays the current firmware settings for
that device.
4. Update to the latest firmware.
Note To search for an ATcommand in XCTU, use the search box .
The relevant commands are:
n AI (Association Indication) reads zero when the device successfully registers to the cellular
network. If it reads 23 it is connecting to the Internet; 22 means it is registering to the cellular
network.
n MY (Module IPAddress) should display a valid IPaddress. If it reads 0.0.0.0, it has not
registered yet.
Note To read a command's value, click the Read button next to the command.
Update to the latest firmware
Firmware is the program code stored in the device's persistent memory that provides the control
program for the device. Use XCTU to update the firmware.
Note If you have already updated the firmware in a previous step, this process is not necessary.
1.
Click the Configuration working modes button .
