The following string will be output after booting the module: l e t l c a e i t u n Q ide f n o CNeul OK After this string has been received, the AT command processor is ready to accept AT commands. 1.1. Definitions : Carriage return character; : Line feed character; <..>: Parameter name. Angle brackets do not appear on command line; [..]: Option parameter. Square brackets do not appear on the command line. 1.2. AT Command Syntax Table 1: AT Commands Syntax Test Command AT+ =? Check possible sub-parameter values Read Command AT+ ? Check current sub-parameter values AT+ =p1[,p2[,p3[.....]]] Set command AT+ Execute command Set Command Execute Command 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. BC95_AT_Commands_Manual Confidential / Released 6 / 58 NB-IoT Module Series BC95 AT Commands Manual 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 „=?‟. They can be used to make the input more human-readable. On input, at least a carriage return is required. A newline character is ignored so it is permissible to use carriage return/line feed pairs on the input. For B600, the AT command processor uses carriage return/line feed pairs (\r\n, 0x0D0A) to end lines on its output. l e t l c a e i t u n Q ide f n o C 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 1.4. 3GPP Compliance 3GPP commands are complied with the 3GPP TS 27.007 v13.5.0 (2016-06). For clarification on 3GPP commands, please refer to this document.

The Active Time value is coded as one byte (octet 3) of the GPRS Timer 2 information element coded as bit format (e.g. “00100100” equals 4 minutes). For the coding and the value range, please refer to the GPRS Timer 2 IE in 3GPP TS 24.008 Table 10.5.163/3Gpp TS 24.008, 3GPP TS 23.682 and 3GPP TS 23.401. String type; one byte in an 8 bit format.

BC95_AT_Commands_Manual Confidential / Released 16 / 58 NB-IoT Module Series BC95 AT Commands Manual 3.6. AT+CSCON Signalling Connection Status This command gives details of the terminal‟s perceived radio connection status (i.e. to the base station). It returns an indication of the current state. Please note that this state is only updated when radio events, such as sending and receiving, take place. This means that the current state may be out of date. The terminal may think it is "Connected" yet cannot currently use a base station due to a change in the link quality. The set command controls the presentation of an unsolicited result code +CSCON. If =1, +CSCON: is sent from the MT when the connection mode of the MT is changed. If =2 and there is a state within the current mode, +CSCON: [, ] is sent from the MT. If =3, +CSCON: [, [, ]] is sent from the MT. If setting fails, an MT error, +CME ERROR: is returned. Refer to Chapter 6 for possible values. l e t l c a e i t u n Q ide f n o C When the MT is in UTRAN or E-UTRAN, the mode of the MT refers to idle when no PS signalling connection and to connected mode when a PS signalling connection between UE and network is setup. When the UE is in GERAN, the mode refers to idle when the MT is in either the IDLE state or the STANDBY state and to connected mode when the MT is in READY state. The value indicates the state of the MT when the MT is in GERAN, UTRAN connected mode or E-UTRAN. The read command returns the status of result code presentation and an integer which shows whether the MT is currently in idle mode or connected mode. State information is returned only when =2. Radio access type information is returned only when =3. Test command returns supported values as a compound value.

This functionality will be added in a future release. Only =0 and =1 are supported. =0 is the default value. l e t l c a e i t u n Q ide f n o C 3.7. AT+CLAC List Available Commands This command lists the available AT commands. Execution command causes the MT to return one or more lines of AT commands. Refer to Chapter 6 for possible values. Please note that this command only returns the AT commands that are available for the user. AT+CLAC List Available Commands Execute Command AT+CLAC Response [ [...]] OK +CME ERROR: AT+CLAC=?

Text shall not contain the sequence 0 or OK OK BC95_AT_Commands_Manual Confidential / Released 19 / 58 NB-IoT Module Series BC95 AT Commands Manual 3.8. AT+CSQ Get Signal Strength Indicator The terminal will provide a current signal strength indicator of 0 to 255 where larger is generally better. This information is based on a single measurement so can be expected to change greatly over short periods of time and may never use all possible (or even the majority) of the entire possible range or codes. Execution command returns received signal strength indication and channel bit error rate from the MT. Refer to Chapter 6 for possible values. l e t l c a e i t u n Q ide f n o C Test command returns values supported as compound values.

AT+CGPADDR Show PDP Addresses This command returns the IP address of the device. The execution command returns a list of PDP addresses for the specified context identifiers. If no is specified, the addresses for all defined contexts are returned. Refer to Chapter 6 for possible values. l e t l c a e i t u n Q ide f n o C The test command returns a list of defined s. These are s that have been activated and may or may not have an IP address associated with them. AT+CGPADDR Show PDP Addresses Execute Command AT+CGPADDR[= [, [,...]]] Response [+CGPADDR: [, [, ]]] [ +CGPADDR: ,[ [, ]] [...]] OK IPv4: The string is given as dot-separated numeric (0-255) parameter of the form: a1.a2.a3.a4 IPv6: The string is given as colon-separated hexadecimal parameter.
