SARA-R4/N4 series - AT Commands Manual 1 AT command settings u-blox cellular modules provide at least one physical serial interface that is compliant to V.24 [26]. When the module is powered on, it enters the command mode. For more details on command mode, see Chapter 1.1. For module and hyper terminal connection and settings see the corresponding evaluation kit user guide. 1.
SARA-R4/N4 series - AT Commands Manual The command description defines each named parameter with its type, its range (valid / acceptable values), the default value (when available) and the factory-programmed value (when applicable). For default value it is intended the value automatically set if the parameter is omitted and at the module power-on (if the command setting is not stored in NVM/profile).
SARA-R4/N4 series - AT Commands Manual 1.1.4.1 Concatenation of AT commands More than one AT command can be entered on the same command line. The "AT" prefix must be provided only at the beginning of the command line. Each command must be separated by using a semicolon as delimiter only if the command has a "+" character as prefix.

SARA-R4/N4 series - AT Commands Manual 2 General operation 2.1 Start up and initialization The characteristics of the boot of the cellular device vary from module to module and are described in the corresponding System Integration Manual; during this phase the module might be not responsive on the AT interface until all necessary SW modules have been installed (e.g. USB drivers); monitoring of the greeting text, where supported, can help in detecting the successful end of the boot phase.
SARA-R4/N4 series - AT Commands Manual 2.2.2 Set command A set command configures the preferred settings for the specified command. The set command is the only way to set the preferred settings in the DCE. For some commands it is possible to store the current settings in the profile or in the non volatile memory and retrieve them in another connection. 2.2.3 Read command A read command provides the current setting of the command parameters. It is used to find out the current command configuration. 2.2.
SARA-R4/N4 series - AT Commands Manual transmit the buffered URCs. Otherwise the collision of the URCs with the subsequent AT command is still possible. In case multiple AT interfaces are available, it should be advisable to use one of the different AT interfaces to manage all the user enabled URCs, while use the others ones to send AT commands and receive their responses. Anyway URCs related to external causes (e.g. RING) are issued on all interfaces. 2.2.

SARA-R4/N4 series - AT Commands Manual The reload of the AT command profile from the NVM also results in the re-application of the +UPSV setting, which is a shared "AT interface configuration". This must be kept in mind, since the change could have impacts on the communication over the UART interface. As mentioned in Definitions, generally there is not difference in the execution of an AT command among the interfaces. But, there are some exceptions due to interface restrictions.
