Scope of the Document This document presents the AT Commands Set for Quectel BG96 series module which includes the following variants: BG96: Multi-mode (LTE Cat M1/NB1/EGPRS) module BG96-M: LTE Cat M1 only module BG96-N: LTE Cat NB1 only module Hereinafter, BG96 series is collectively called BG96 unless otherwise specified. 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 BG96 is a combination of 3GPP TS 27.007, 3GPP TS 27.005 and ITU-T recommendation V.25ter as well as 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. BG96_AT_Commands_Manual 8 / 208 LTE Module Series BG96 AT Commands Manual Extended syntax These commands can be operated in several modes, as following table: 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. 1.3. Supported Character Sets BG96 AT command interface defaults to the GSM character set. BG96 module supports the following character sets: GSM format UCS2 IRA The character set can be configured and interrogated by using the AT+CSCS command (3GPP TS 27.007) and it is defined in 3GPP TS 27.005. The character set affects transmission and reception of SMS and SMS Cell Broadcast Messages, as well as the entry and display of phone book entries text field. 1.4. AT Command Interface BG96 AT command interface includes two USB ports (USB MODEM port and USB AT port) and one main UART port. The main UART port and two USB ports support AT command communication and data transfer. 1.5. Unsolicited Result Code As an Unsolicited Result Code and a report message, URC is not issued as part of the response related BG96_AT_Commands_Manual 9 / 208 LTE Module Series BG96 AT Commands Manual to an executed AT command. URC is issued by BG96 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. 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 POWERED DOWN and sets the STATUS 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 STATUS pin is set as low and the URC POWERED DOWN is outputted. If POWERED DOWN cannot be received within 65s, the VBAT shall be switched off compulsorily. BG96_AT_Commands_Manual 10 / 208 LTE Module Series BG96 AT Commands Manual 2 General Commands 2.1.
