Definitions : Carriage return character; : Line feed character; <..>: Parameter name. Angle brackets do not appear on command line; [..]: Optional parameter. Square brackets do not appear on the command line. 1.2. AT Command Syntax Table 1: AT Command Syntax 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+ =p1[,p2[,p3[... ..]]] This command sets the user-definable parameter values. Execution Command AT+ This command reads non-variable parameters affected by internal processes in the Module engine. Multiple commands can be placed on a single line using a semi-colon (“;”) between commands. Only the first command should have AT prefix. Commands can be in upper or lower case. When entering AT commands spaces are ignored except in the following cases: Within quoted strings, where they are preserved; Within an unquoted string or numeric parameter; Within an IP address; Within the AT command name up to and including a ‘=’, ‘?’ or ‘=?’. BC26_LwM2M_AT_Commands_Manual 6 / 24 NB-IoT Module Series BC26 AT Commands Update If no command is entered after the AT token, "OK" will be returned. If an invalid command is entered, “ERROR” will be returned. Optional parameters, unless explicitly stated, need to be provided up to the last parameter being entered. 1.3. AT Command Responses When the AT Command processor has finished processing a line, it will output either "OK" or "ERROR" indicating that it is ready to accept a new command. Solicited informational responses are sent before the final "OK" or "ERROR". Unsolicited information responses will never occur between a solicited informational response and the final “OK” or “ERROR”. Responses will be of the format: +CMD1: OK Or OK BC26_LwM2M_AT_Commands_Manual 7 / 24 NB-IoT Module Series BC26 AT Commands Update 2 Implementation Status Table 2: Types of AT Commands and Implementation Status AT Command Description Implementation Status AT+QLWSERV Configure the IoT Platform Address and Port R01A04 AT+QLWCONF Configure the IoT Platform Parameters R01A04 AT+QLWADDOBJ Add a LwM2M Object R01A04 AT+QLWDELOBJ Delete a LwM2M Object R01A04 AT+QLWOPEN Send a Register Request R01A04 AT+QLWUPDATE Send an Update Request R01A04 AT+QLWCLOSE Send a Deregister Request R01A04 AT+QLWDATASEND Send Data with Mode R01A04 AT+QLWDATASTATUS Query CON Messages Sent Status R01A04 AT+QLWDEL Delete the LwM2M Configuration R01A04 AT+QLWRD Receive Data from Buffer R01A04 AT+QLWCFG Configure Optional Parameters R01A05 NOTE "*" means the commands listed in this chapter are under development.
