Scope of the Document l e t l c a e i t u n Q ide f n o C This document presents the AT Commands Set for Quectel cellular engine UC15. 1.2. AT Command Syntax The “AT” or “at” prefix must be set at the beginning of each command line. To terminate a command line enter . Commands are usually followed by a response that includes “ ”. Throughout this document, only the responses are presented, “ ” are omitted intentionally. The AT Commands Set implemented by UC15 is a combination of 3GPP TS 27.007, 3GPP TS 27.005 and ITU-T recommendation V.25ter and the AT Commands developed by Quectel. All these AT commands can be split into three categories syntactically: “basic”, “S parameter”, and “extended”. They are listed as follows: Basic syntax These AT commands have the format of “AT ”, or “AT& ”, where “ ” is the command, and “ ” is/are the argument(s) for that command. An example of this is “ATE ”, which tells the DCE whether received characters should be echoed back to the DTE according to the value of “ ”. “ ” is optional and a default will be used if it is missing. S parameter syntax These AT commands have the format of “ATS = ”, where “ ” is the index of the S register to set, and “ ” is the value to assign to it. Extended syntax These commands can be operated in several modes, as following table: UC15_AT_Commands_Manual Confidential / Released 9 / 234 UMTS/HSPA Module Series UC15 AT Commands Manual Table 1: Types of AT Commands and Responses Test Command AT+ =? This command returns the list of parameters and value ranges set by the corresponding Write Command or internal processes. Read Command AT+ ? This command returns the currently set value of the parameter or parameters. Write Command AT+ =<…> This command sets the user-definable parameter values. Execution Command AT+ This command reads non-variable parameters affected by internal processes in the UE l e t l c a e i t u n Q ide f n o C 1.3. Supported Character Sets The UC15 AT command interface defaults to the GSM character set. The UC15 supports the following character sets: GSM UCS2 IRA The character set can be configured and interrogated by using the “AT+CSCS” command (3GPP TS 27.007). The character set is defined in 3GPP TS 27.005. The character set affects transmission and reception of SMS and SMS Cell Broadcast Messages, the entry and display of phone book entries text field. 1.4. AT Command Interface The UC15 AT command interface includes two USB ports (USB MODEM port and USB AT port) and one main UART port. Both the USB MODEM port and the main UART port support AT command and data transfer. The USB AT port only supports AT command. UART Port Feature: The baud rates of 9600, 19200, 38400, 57600, 115200, 230400, 460800, 921600, 3200000, 3686400 and 4000000 are supported at present. The default is 115200. The main UART port supports hardware flow control lines RTS and CTS. But it is off by default. AT command “AT+IFC=2,2” is used to enable hardware flow control. UC15_AT_Commands_Manual Confidential / Released 10 / 234 UMTS/HSPA Module Series UC15 AT Commands Manual 1.5. Unsolicited Result Code As an Unsolicited Result Code and a report message, URC is not issued as part of the response related to an executed AT command. URC is issued by the UC15 without being requested by the TE and it is issued automatically when a certain event occurs. Typical events leading to URCs are incoming calls ("RING"), received short messages, high/low voltage alarm, high/low temperature alarm etc. For most of these messages, they will be outputted from USB AT port by default if CMUX function is disabled, and you can configure the interface for URC output by using the AT command "AT+QURCCFG" (This command only effects when CMUX function is disabled). If CMUX function is enabled, URCs will be outputted from CMUX2 port by default. While the interface used for URC output is reserved by an active data connection or a long running AT command, URCs are buffered internally and will be issued after the interface becomes idle status. l e t l c a e i t u n Q ide f n o C 1.6. Turn off Procedure It is recommended to execute AT+QPOWD command to turn off the module, as it is the safest and best way. This procedure is realized by letting the module log off from the network and allowing the software to enter into a secure and safe data state before disconnecting the power supply. After sending AT+QPOWD, do not enter any other AT commands. The module outputs message “POWERED DOWN” and sets the STATE pin as low to enter into the shutdown state. In order to avoid data loss, it is suggested to wait for 1s to switch off the VBAT after the STATE pin is set as low and the URC “POWERED DOWN” is outputted. If “POWERED DOWN” has not been received after 65s, you should force to switch off the VBAT.
