Dual stack IPv4/IPv6
The modules support both Internet Protocol version 4 and Internet Protocol version 6.
For more details about dual stack IPv4/IPv6, see the u-blox AT commands manual

Smart temperature management
☞
Not supported by the “00” product version.
Cellular modules – independently from the specific model – always have a well-defined operating
temperature range. This range should be respected to guarantee full device functionality and long life
span.
Nevertheless there are environmental conditions that can affect operating temperature, e.g. if the
device is located near a heating/cooling source, if there is/isn’t air circulating, etc.
The module itself can also influence the environmental conditions; such as when it is transmitting at
full power. In this case, its temperature can increase very quickly and can raise the temperature
nearby.
The best solution is always to properly design the system where the module is integrated.
Nevertheless, having an extra check/security mechanism embedded into the module is a good
solution to prevent operation of the device outside of the specified range.
Smart temperature supervisor (STS)
The smart temperature supervisor is activated and configured by a dedUSTS AT command
(for more details, see the u-blox AT commands manual
). A URC indication is provided once the
feature is enabled and at the module power-on.
The cellular module measures the internal temperature (Ti) and its value is compared with predefined
thresholds to identify the actual working temperature range.
☞
The temperature measurement is done inside the module: the measured value could be different
from the environmental temperature (Ta).
