User manual TELTONIKA TM2 AT COMMANDS MANUAL

[. . . ] TM2 AT Commands Manual History Company was established on 15th of April 1998. In 2001 company expanded its fields of activity by starting design and manufacturing of electronical systems for wireless data transfer. In 2002 contract of partnership and collaboration was signed with company Pro-Sign GmbH (Germany), considering design and representation of graphic programming interface iCon-L in Eastern Europe. In 2003 Teltonika and NOKIA became partners and started integration of NOKIA M2M technology using NOKIA N12 module. [. . . ] 14. 3. 2 Syntax Command syntax: AT&C[<value>] Command AT&C Possible responses OK or +CME ERROR: <error> 94 TM2 AT Guide 14. 3. 3 Defined values <value> indicates the behaviour of circuit 109 as follows: - 0: the DCE always presents the ON condition on circuit 109 - 1: circuit 109 changes in accordance with the underlying DCE, which may include functions other than the physical layer functions If the parameter is not inserted, the value is set to 0. 14. 4 Circuit 108/2 behavior &D 14. 4. 1 Description This command determines how the DCE responds when circuit 108/2 is changed from ON to OFF condition during on-line data state. This behaviour is provided for the CSD data calls in conformance to the V25-ter spec[20]. Please note that for a GPRS data transfer session with a context activated and a PPP L2 protocol, when circuit 108/2 is changed from ON to OFF condition, the data transfer is terminated and the context is deactivated. 14. 4. 2 Syntax Command syntax: AT&D[<value>] Command AT&D1 Possible responses OK or +CME ERROR: <error> 14. 4. 3 Defined values <value> may be: - 0: the DCE ignores circuit 108/2 - 1: upon an ON-to-OFF transition of circuit 108/2, the DCE enters online command state and issues an OK result code - 2: upon an ON-to-OFF transition of circuit 108/2, the DCE instructs the underlying DCE to perform an orderly cleardown of the call. If the parameter is not inserted, the value is set to 0. 14. 5 ~+++ behaviour in GPRS &D A special meaning of the &D value is provided for the ~+++ sequence during a GPRS data transfer (this is outside the V25-ter specification scope). The ~+++ lead to a context deactivation during a GPRS data transfer session for the AT&D0, AT&D1 values (please note that the +++ return to on-line command mode is provided for each &D value during a CSD data call [20]). A different implementation for the ~+++ is done with the &D2 value: GPRS data transfer is escaped and system returns in the on-line command state. During the on-line command mode different AT commands can be sent but some limitations are present: - data calls in GPRS on-line command mode cannot be granted (please activate the AT+CRC=1 mode in order to identify the kind of call and reject data incoming calls if GPRS is in the on-line command mode); - if provided, the MUX functionalities cannot be used in cooperation with the GPRS on-line command mode (please note that the MUX is a specific feature, not available in all the platforms) Circuit 108/2, +++ behaviour for the different &D: summarizing table 95 TM2 AT Guide CSD +++ &D0 &D1 &D2 Command mode Command mode Command mode DTR On to Off in data state Data state Command mode Cleardown call ~+++ GPRS DTR On to Off in data state Context deactivation Context deactivation Context deactivation Context deactivation Context deactivation Command mode (with limitations) 14. 6 DSR override &S 14. 6. 1 Description This command selects how the modem will control DSR (V. 24 control line 107). 14. 6. 2 Syntax Command syntax: AT&S[<value>] Command AT&S Possible responses OK or +CME ERROR: <error> 14. 6. 3 Defined values <value> indicates the behaviour as follows: - 0: sets the DSR line to ON - 1: sets the DSR line to OFF 14. 7 Flow control &K 14. 7. 1 Description This command controls the flow control mechanism. 14. 7. 2 Syntax Command syntax: AT&K[<value>] Command AT&K3 Possible responses OK or +CME ERROR: <error> 14. 7. 3 Defined values <value> may be: - 0: disable DTE flow control 96 TM2 AT Guide - 3: enable RTS/CTS DTE flow control (default for data modems) - 4: enable XON/XOFF DTE flow control - 5: enable XON/XOFF DTE flow control - 6: enable XON/XOFF DTE flow control If the parameter is not inserted, the value is set to 0. 14. 8 Store current configuration &W 14. 8. 1 Description This command stores the current active configuration into one of the two user profiles in NVRAM as denoted by the parameter value. The profile is stored for the terminal where the storing is requested. The AT commands with the related parameters that are stored in the user profiles are reported in the following: - AT&C: Circuit 109 behavior; - AT&D: Circuit 108 behavior; - AT&K: Flow control; - ATE: Echo mode; - ATQ: Response Suppression Mode; - ATV: Response Formatting Mode; - ATX: Call Progress Monitoring Control; - ATS0: Automatic answer; - ATS2:Escape character; - ATS3: Command line termination character; - ATS4: Response formatting character; - ATS5: Command line editing character; - ATS7: Connection completion timeout; - AT+CBST: Data Rate, Bearer Service, Connection Element; - AT+CRLP: RlpIws (IWF to MS window size), RlpMws (MS to IWF window size), Rlp96T1 (acknowledgement timer T1), RlpN2 (retransmission attempts N2); - AT+CR: Service Report Control Mode; - AT+CRC: Cellular Result Mode; - +BR (+IPR saved value): Baud Rate; - AT+COPS: Cops mode, Cops PLMN to Register; - AT+NMGC: Microphone Gain Control; - AT+NSGC: Speaker Gain Control; - AT+NSTN: Sidetone; - AT+NUBF: Uplink Biquad Filters; - AT+NDBF: Downlink Biquad Filters; - AT+NHFP: Hand Free Parameters; - AT+ICF: DTE-DCE character framing; - AT+NPSV: Power saving control. 97 TM2 AT Guide 14. 8. 2 Syntax Command syntax: AT&W[<value>] Command Set command AT&W<value> Possible responses OK or +CME ERROR: <error> 14. 8. 3 Defined values <value> may be: - 0: selects profile 0 - 1: selects profile 1 If the parameter is not inserted, the value is set to 0.
