DB (Cellular Signal Strength)
Reads the absolute value of the current signal strength to the cell tower in dB. If DB is blank, the XBee
Smart Modem has not received a signal strength from the cellular component.
DB only updates when the modem is registered with the celllular tower. It is updated periodically, and
not when read.
Parameter range
0x71 - 0x33 (-113 dBm to -51 dBm) [read-only]
Default
N/A
AN (Access Point Name)
Specifies the packet data network that the modem uses for Internet connectivity. This information is
provided by your cellular network operator. After you set this value, applying changes with AC (Apply
Changes) or CN (Exit Command mode) triggers a network reset.
See Network connection issues if the XBee Smart Modem is not joining the network.
Parameter range
1 - 100 ASCII characters
Default
-
CP (Carrier Profile)
Configures the cellular component to select network operator settings (RF bands, packet data
configuration) for various networks.
The default setting of 0 (autodetect) increases the boot time.
The 1 (No Profile) setting should be used if the module is not able to join the network because the
underlying cellular modem does not have a predefined profile that supports the inserted SIMcard. The
1 (No Profile) setting does not use any predefined profiles, which forces the module to attempt to
join an appropriate network based on the module's current configuration.
Changes to the value only take effect on boot so a reboot or power cycle is required for any changes
to become active.
Parameter range
0 - 3
Value Description
0 Autodetect from inserted ICCID (SIM) [default]
