MC35i AT Command Set

MC35i AT Command Set8.2 AT+COPS8.2 AT+COPS Operator SelectionAT+COPS queries the present status of the MC35i's network registration and allows to determine whether automaticor manual network selection shall be used.Three operator selection modes are available:• AutomaticMC35i searches for the home operator automatically. If successful the MC35i registers to the home network.If the home network is not found, MC35i goes on searching. If a permitted operator is found, MC35i registersto this operator.If no operator is found the MC35i remains unregistered.• ManualDesired operator can be determined using the AT+COPS write command. If the operator is found, MC35i registersto it immediately. If the selected operator is forbidden, the MC35i remains unregistered.• Manual/automaticThe ME first tries to find the operator determined via AT+COPS write command. If the ME fails to register tothis operator, then it starts to select another (permitted) operator automatically.The AT+COPS test command lists sets of four parameters, each representing an operator present in the network.A set consists of• an integer indicating the availability of the operator,• long alphanumeric format of the operator's name and• numeric format representation of the operator.Any of the parameters may be unavailable and will then be an empty field (,,). The list of operators comes in thefollowing order: Home network, networks referenced in SIM and other networks.The operator list is followed by a list of the supported s and s. These lists are delimited fromthe operator list by two commas.If the test command is used during an ongoing GPRS transfer, traffic will be interrupted for up to one minute.The AT+COPS read command returns the current and the currently selected operator. If no operator isselected, and are omitted.The AT+COPS write command forces an attempt to select and register to the GSM network operator (see notebelow). If the selected operator is not available, no other operator will be selected (except =4). Theselected operator name will apply to further read commands, too.Command settings are effective over all serial interfaces of the MC35i.SyntaxTest CommandAT+COPS=?Response(s)+COPS: [list of present operators (, long alphanumeric s,,numeric s ], , (list ofsupported s), (list of supported s)OKERROR+CME ERROR: Read CommandAT+COPS?Response(s)+COPS:[, [, ]]OKERROR+CME ERROR: MC35i_ATC_V02.00nConfidential / ReleasedPage 148 of 3909/10/08
