TOBY-L2 series - Data Sheet UBX-13004573 - R07  Objective Specification  Functional description   Page 9 of 47 1.6 Supported features Table 3 lists the main features supported by  TOBY-L2 modules. For more details see TOBY-L2 / MPCI-L2 series System Integration Manual [2] and u-blox AT Commands Manual [1].  Feature Description Network Indication4 GPIO configured to indicate the network status: registered home network, registered roaming, voice or data call enabled, no service. The feature can be enabled through the +UGPIOC AT command. Antenna Detection5 The ANT_DET pin provides antenna presence detection capability, evaluating the resistance from ANT1 and ANT2 pins to GND by means of an external antenna detection circuit implemented on the application board.  The antenna detection feature can be enabled through the +UANTR AT command. Jamming detection5 Detects “artificial” interference that obscures the operator’s carriers entitled to give access to the radio service and reports the start and stop of such conditions to the application processor (AP). The AP can react appropriately by e.g. switching off the radio transceiver to reduce power consumption and monitoring the environment at regular intervals. The feature can be enabled and configured through the +UCD AT command. Embedded TCP and UDP stack6 Embedded TCP/IP and UDP/IP stack including direct link mode for TCP and UDP sockets. Sockets can be set in Direct Link mode to establish a transparent end to end communication with an already connected TCP or UDP socket via serial interface. FTP6, FTPS5 File Transfer Protocol as well as Secure File Transfer Protocol (SSL encryption of FTP control channel) functionalities are supported via AT commands. HTTP6, HTTPS5 Hyper-Text Transfer Protocol as well as Secure Hyper-Text Transfer Protocol (SSL encryption) functionalities are supported via AT commands. HEAD, GET, POST, DELETE and PUT operations are available. GNSS via modem5 Full access to u-blox positioning chips and modules is available through a dedicated DDC (I2C) interface. This means that from any host processor a single serial port can control the cellular module and the positioning chip or module. For more details see the GNSS Implementation Application Note [5]. Embedded AssistNow Software5 Embedded AssistNow Online and AssistNow Offline clients are available to provide better GNSS performance and faster Time-to-First-Fix. An AT command can enable / disable the clients. CellLocate®5 Enables the estimation of device position based on the parameters of the mobile network cells visible to the specific device based on the CellLocate® database:  Normal scan: only the parameters of the visible home network cells are sent  Deep scan: the parameters of all surrounding cells of all mobile operators are sent CellLocate® is available via a set of AT commands for CellLocate® service configuration and position request. Hybrid Positioning5 The current module position is provided by a u-blox positioning chip or module or the estimated position from CellLocate® depending on which method provides the best and fastest solution according to the user configuration. Hybrid positioning is available via a set of AT commands that allow the configuration and the position request. Wi-Fi via modem7 Full access to u-blox short range communication Wi-Fi modules is available through a dedicated SDIO interface.  This means that from any host processor a single serial port can control the cellular module and the short range communication module.  All the management software for the Wi-Fi module operations runs inside the cellular module in addition to those required for cellular-only operation: Wi-Fi driver, Web User Interface (WebUI), Connection Config Manager. For more details see the Wi-Fi / Cellular Integration Application Note [8]. Firmware update Over AT commands (FOAT) Firmware module update over AT command interfaces (UART, USB). The feature can be enabled and configured through the +UFWUPD AT command. Firmware update Over The Air (FOTA)6 Firmware module update over the LTE/3G/2G air interface.

TOBY-L2 series - Data Sheet UBX-13004573 - R07  Objective Specification  Functional description   Page 10 of 47 Feature Description Smart Temperature Supervisor8 Constant monitoring of the module board temperature:  Warning notification when the temperature approaches an upper or lower predefined threshold  Shutdown  notified  and  forced  when  the  temperature  value  is  outside  the  specified  range  (shutdown suspended in case of an emergency call in progress) The Smart Temperature Supervisor feature can be enabled and configured through the +USTS AT command.  The sensor measures board temperature, which can differ from ambient temperature. SIM Access Profile (SAP)8 Allows access and use of a remote SIM card/chip instead of the local SIM card/chip directly connected to the module SIM interface. The module acts as an SAP client establishing a connection and performing data exchange to an SAP server directly connected to the remote SIM. The modules provide a dedicated USB SAP channel and dedicated multiplexer SAP channel over UART for communication with the remote SIM card. In-Band Modem8 In-Band modem solution for eCall and ERA-GLONASS emergency call applications over cellular networks implemented according to the 3GPP TS 26.267 specification [13] When activated, the in-vehicle eCall / ERA-GLONASS system (IVS) creates an emergency call carrying both voice and data (including vehicle position data) directly to the nearest Public Safety Answering Point (PSAP) to determine whether rescue services should be dispatched to the known position. Power saving The power saving configuration is by default disabled, but it can be enabled and configured using the +UPSV AT command. When the power saving is enabled, the module automatically enters the low power idle-mode whenever possible, reducing current consumption. During idle-mode, the module processor core runs with the RTC 32 kHz reference clock, which is generated by the internal 32 kHz oscillator. SMS via IMS9 Allows SMS via embedded IP Multimedia Subsystem Table 3: TOBY-L2 series main supported features   u-blox  is  extremely  mindful  of  user  privacy.  When  a  position  is  sent  to  the  CellLocate®  server  u-blox  is unable to track the SIM used or the specific device.                                                        8 Not supported by “00”, “01” and “50” product versions. 9 Not supported by “00” and “50” product versions.
TOBY-L2 series - Data Sheet UBX-13004573 - R07  Objective Specification  Interfaces   Page 11 of 47 2 Interfaces 2.1 Power management 2.1.1 Module supply input (VCC) TOBY-L2 series modules must be supplied through the VCC pins by a DC power supply. Voltage must be stable, because during operation the current drawn from VCC can vary significantly, based on the power consumption profile of the LTE/3G/2G technologies (described in the TOBY-L2 / MPCI-L2 series System Integration Manual [2]). 2.1.2 RTC supply input / output (V_BCKP) When VCC voltage is within the valid operating range, the internal Power Management Unit (PMU) supplies the Real Time Clock (RTC) and the same supply voltage is available on the V_BCKP pin. If the VCC voltage is under the minimum operating limit (e.g. during not powered mode), the V_BCKP pin can externally supply the RTC. 2.1.3 Generic digital interfaces supply output (V_INT) TOBY-L2 series modules provide a 1.8 V supply rail output on the V_INT pin, which is internally generated when the module is switched on. The same voltage domain is used internally to supply the generic digital interfaces of the modules. The V_INT supply output can be used in place of an external discrete regulator.  2.2 Antenna interfaces 2.2.1 Antenna RF interfaces The  modules  have  two  RF  pins  with  a  characteristic  impedance  of  50  .  The  primary  antenna  pin  (ANT1) supports  both  Tx  and  Rx,  providing  the  main  antenna  interface,  while  the  secondary  antenna  pin  (ANT2) supports Rx only for the LTE MIMO 2x2 and 3G Rx diversity configurations. 2.2.2 Antenna detection  The antenna detection is not supported by “00”, “01” and “50” product versions. The  ANT_DET  pin is  an  Analog to  Digital  Converter  (ADC)  input  with  a  current  source  provided  by TOBY-L2 modules  to  sense  the  antenna  presence  (as  an  optional  feature).  It  evaluates  the  resistance  from  ANT1  and ANT2 pins to  GND  by means of  an  external  antenna detection circuit  implemented on  the  application board. (For more details, see the TOBY-L2 / MPCI-L2 series System Integration Manual [2] and the u-blox AT Commands Manual [1].)  2.3 System functions 2.3.1 Module power-on  TOBY-L2 series can be switched on in one of the following ways:  Rising edge on the VCC pin to a valid voltage for module supply, i.e. applying module supply  Low  level  on  the  PWR_ON  pin,  which  is  normally  set  high  by  an  internal  pull-up,  for  a valid  time  period when  the  applied  VCC  voltage  is  within  the  valid  operating  range  (see  section  4.2.8).  The  PWR_ON  line should be driven by open drain, open collector or contact switch.
TOBY-L2 series - Data Sheet UBX-13004573 - R07  Objective Specification  Interfaces   Page 12 of 47  Low  level  on  the  RESET_N  pin,  which  is  normally  set  high  by  an  internal  pull-up,  for  a  valid time  period when  the  applied  VCC  voltage  is  within  the  valid  operating  range  (see  section  4.2.9).  The  RESET_N  line should be driven by open drain, open collector or contact switch.  RTC alarm, i.e. pre-programmed scheduled time by AT+CALA command  2.3.2 Module power-off TOBY-L2 series can be properly switched off by:  AT+CPWROFF  command  (see  the  u-blox  AT  Commands  Manual  [1]).  The  current  parameter  settings  are saved in the module’s non-volatile memory and a proper network detach is performed. An abrupt under-voltage shutdown occurs on TOBY-L2 series modules when the VCC supply is removed. If this occurs,  it  is  not  possible  to  store  the  current  parameter  settings  in  the  module’s  non-volatile  memory  or  to perform the proper network detach. An abrupt shutdown occurs on TOBY-L2 series modules when a low level is applied on the RESET_N pin, which is normally set high by an internal pull-up, for a valid time period (see the section 4.2.9). This causes an abrupt shutdown of the module: the current parameter settings are not saved in the module’s non-volatile memory and a proper network detach is not performed. An  over-temperature  or  an under-temperature  shutdown  occurs  on  TOBY-L2  modules  when  the  temperature measured within the cellular module reaches the dangerous area, if the optional Smart Temperature Supervisor feature is enabled and configured by the dedicated AT command. For more details see the  TOBY-L2 / MPCI-L2 series System Integration Manual [2] and the u-blox AT Commands Manual [1], +USTS AT command.   Smart Temperature Supervisor is not supported by “00”, “01” and “50” product versions.  2.3.3 Module reset TOBY-L2 series modules can be reset (rebooted) by:  AT+CFUN  command  (see  the  u-blox  AT  Commands  Manual [1]).  This  causes  an  “internal”  or  “software” reset of the module. The current parameter settings are saved in the module’s non-volatile memory and a proper network detach is performed. An  abrupt  “external”  or  “hardware”  reset  occurs  when  a  low  level  is  applied  to  the  RESET_N  pin,  which  is normally set high by an internal pull-up, for a valid time period (see the section 4.2.9). This causes an “external” or “hardware” reset of the module. The current parameter settings are not saved in the module’s non-volatile memory and a proper network detach is not performed. The RESET_N line should be driven by open drain, open collector or contact switch.  2.3.4 Module configuration selection by host processor  The  selection  of  the  module  configuration  by  the  host  application  processor  over  HOST_SELECT0  and HOST_SELECT1 pins is not supported by “00”, “01” and “50” product versions.  TOBY-L2  series  modules  include  two  input  pins  (HOST_SELECT0,  HOST_SELECT1)  for  the  selection  of  the module configuration by the host application processor.
TOBY-L2 series - Data Sheet UBX-13004573 - R07  Objective Specification  Interfaces   Page 13 of 47 2.4 SIM 2.4.1 SIM interface A  SIM  card  interface  is  provided  on  the  VSIM,  SIM_IO,  SIM_CLK,  SIM_RST  pins:  the  high-speed  SIM/ME interface is implemented as well as the automatic detection of the required SIM supporting voltage. Both 1.8 V and 3  V SIM types are supported  (1.8 V and 3 V ME).  Activation and deactivation with automatic voltage  switch  from  1.8  V  to  3  V  is  implemented,  according  to  ISO-IEC  7816-3  specifications.  The  SIM  driver supports the PPS procedure for baud-rate selection, according to the values proposed by the SIM card/chip. 2.4.2 SIM detection  The SIM detection is not supported by “00”, “01” and “50” product versions.  TOBY-L2 series modules provide the SIM detection function over GPIO to sense the SIM card physical presence (as  an  optional  feature)  when  the  specific  GPIO  pin  of  the  module  is  properly  connected  to  the  mechanical switch of the SIM car holder (for more details see the TOBY-L2 / MPCI-L2 series System Integration Manual [2]). 2.5 Serial communication TOBY-L2 series provides the following serial communication interfaces:  UART interface: asynchronous serial interface available  for the communication with a DTE host application processor (AT commands, data communication, FW update by means of FOAT) and for diagnostic   USB  interface:  High-Speed  USB  2.0  compliant  interface  available  for  the  communication  with  a  USB  host application processor (AT commands, data communication, FW update by means of the FOAT feature), for FW update by means of the u-blox EasyFlash tool and for diagnostic   DDC interface: I2C bus compatible interface available for the communication with u-blox GNSS positioning chips/modules and with external I2C devices as an audio codec  SDIO interface: Secure Digital Input Output interface available for the communication with an external Wi-Fi chip or module 2.5.1 UART interface  The UART interface is not supported by TOBY-L200-00S and TOBY-L210-00S modules versions.  The DTR, DSR and DCD signals are not supported by TOBY-L200-50S, TOBY-L210-50S modules versions.  TOBY-L2  series  modules  include a  9-wire  unbalanced  asynchronous  serial interface  (UART)  for communication with  an  application  host  processor  (AT  commands,  data  communication,  FW  update  by  means  of  the  FOAT feature) and for diagnostic purpose. UART features are:  Complete  serial  port  with  RS-232  functionality  conforming  to  the  ITU-T  V.24  Recommendation  [17],  with CMOS compatible signal levels (0 V for low data bit or ON state and 1.8 V for high data bit or OFF state)  Data lines (RXD as output, TXD as input), hardware flow control lines (CTS as output, RTS as input), modem status and control lines (DTR as input, DSR as output, DCD as output, RI as output) are provided  Hardware flow control (default value), software flow control, or none flow control are supported   Software flow control is not supported by “00”, “01” and “50” module product versions.
TOBY-L2 series - Data Sheet UBX-13004573 - R07  Objective Specification  Interfaces   Page 14 of 47  Power saving indication available on the  hardware flow  control output (CTS  line): the  line is driven to the OFF state when the module is not prepared to accept data by the UART interface  Power saving control over the RTS input or the DSR input can be enabled via AT+UPSV command (for more details see u-blox AT Commands Manual [1] and TOBY-L2 / MPCI-L2 series System Integration Manual [2])  The  following  baud  rates  are  supported:  9600,  19200,  38400,  57600,  115200  (default  baud  rate  when autobauding is disabled or not supported), 230400, 460800 and 921600 b/s   One-shot autobauding is supported and it is by default enabled: automatic baud rate detection is performed only once, at module start up. After the detection, the module works at the fixed baud rate (the detected one) and the baud rate can only be changed via AT command (see u-blox AT Commands Manual [1], +IPR).   The automatic baud rate recognition (autobauding) is not supported by “50” module product version.   Frame format can be: o 8N2 (8 data bits, no parity, 2 stop bits) o 8N1 (8 data bits, no parity, 1 stop bit), default frame configuration o 8E1 (8 data bits, even parity, 1 stop bit) o 8O1 (8 data bits, odd parity, 1 stop bit) o 7N2 (7 data bits, no parity, 2 stop bits) o 7N1 (7 data bits, no parity, 1 stop bit) o 7E1 (7 data bits, even parity, 1 stop bit) o 7O1 (7 data bits, odd parity, 1 stop bit)   Automatic frame format recognition is not supported by “00”, “01” and “50” module product versions.  UART serial interface can be conveniently configured through AT commands. For more details see the u-blox AT Commands Manual [1]  (+IPR, +ICF, +IFC,  &K, \Q,  +UPSV  AT command)  and TOBY-L2 /  MPCI-L2  series System Integration Manual [2].  2.5.1.1 Multiplexer protocol   The  GNSS tunneling and  the  SIM  Access Profile  (SAP)  multiplexer  virtual channels  are  not  supported by “00”, “01” and “50” modules product version.  TOBY-L2 series modules include multiplexer functionality as per 3GPP TS 27.010 [12] on the UART physical link. This  is  a  data  link  protocol  which  uses  HDLC-like  framing  and  operates  between  the  module  (DCE)  and  the application processor (DTE), allowing a number of simultaneous sessions over the physical link (UART): the user can concurrently use AT interface on one MUX channel and data communication on another MUX channel. The following virtual channels are defined (for more details, see the Mux Implementation Application Note [6]):  Channel 0: control  Channel 1 – 5: AT commands / data connection  Channel 6: GNSS tunneling  Channel 7: SIM Access Profile (SAP)
TOBY-L2 series - Data Sheet UBX-13004573 - R07  Objective Specification  Interfaces   Page 15 of 47 2.5.2 USB interface TOBY-L2 series modules include a high-speed USB 2.0 compliant interface with maximum 480 Mb/s data rate, representing the main interface for transferring high speed data with a host application processor. The module itself acts as a USB device and can be connected to any USB host equipped with compatible drivers. The  USB_D+ / USB_D-  lines  carry  the  USB  data  and  signaling,  providing  all  the  functionalities  for  the  bus attachment, configuration, enumeration, suspension or remote wakeup according to USB 2.0 specification [18].  The additional VUSB_DET input is available as an optional feature to sense the host VBUS voltage (5.0 V typical).   The VUSB_DET functionality is not supported by “00”, “01” and “50” product versions: the pin should be  left  unconnected  or  it  should  not  be  driven  high  by  any  external  device,  because  a  high  logic  level applied to the pin will represent a module switch-on event (additional to the ones listed in section 2.3.1) and will prevent reaching the minimum possible consumption with power saving enabled.  TOBY-L2 series modules provide by default the following set of USB functions:  CDC-ACM modem: AT commands interface is available over this modem COM port  RNDIS network adapter: Ethernet-over-USB connection is available over this network adapter  The USB of TOBY-L2 series modules can be configured by the AT+UUSBCONF command to select different sets of USB functions available in a mutually exclusive way. The configured USB profile can thus consist of a specific set of functions with various capabilities and purposes, such as:  CDC-ACM for AT commands and data  CDC-ACM for GNSS tunneling  CDC-ACM for SIM Access Profile (SAP)  CDC-ACM for diagnostic  RNDIS for Ethernet-over-USB  CDC-ECM for Ethernet-over-USB  CDC-NCM for Ethernet-over-USB  MBIM for Ethernet-over-USB   CDC-ACM  for  GNSS  tunneling,  CDC-ACM  for  SIM  Access  Profile  (SAP),  CDC-NCM  and  MBIM  are  not supported by “00”, “01” and “50” product versions.  For  more  details  regarding  the  USB  configurations  and  capabilities,  see  the  TOBY-L2  /  MPCI-L2  series  System Integration Manual [2] and the u-blox AT Commands Manual [1], +UUSBCONF AT command.  USB drivers are available for the following operating system platforms:  Windows Vista  Windows 7  Windows 8  Windows 8.1  Windows Embedded Compact 7 TOBY-L2 series modules are compatible with standard Linux/Android USB kernel drivers.
TOBY-L2 series - Data Sheet UBX-13004573 - R07  Objective Specification  Interfaces   Page 16 of 47 2.5.3 DDC (I2C) interface  The DDC (I2C) interface is not supported by “00”, “01” and “50” product versions.  TOBY-L2 series modules include an I2C-bus compatible DDC interface (SDA, SCL) available to communicate with a  u-blox  GNSS  receiver  and  with  external  I2C  devices  as  an  audio  codec:  the  TOBY-L2  module  acts  as  an  I2C master which can communicate with I2C slaves in accordance with the I2C bus specifications [19]. For more details regarding the DDC (I2C) interface usage and the integration with a u-blox GNSS receiver see the TOBY-L2 / MPCI-L2 series System Integration Manual [2], the GNSS Implementation Application Note [7], and the I2C and GNSS AT commands description in the u-blox AT Commands Manual [1].  2.5.4 SDIO interface  The SDIO interface is not supported by “00”, “01” modules product versions.  TOBY-L2  series modules  include  a 4-bit Secure Digital Input Output  interface (SDIO_D0, SDIO_D1, SDIO_D2, SDIO_D3, SDIO_CLK, SDIO_CMD) designed to communicate with an external u-blox short range Wi-Fi module: the TOBY-L2 cellular module acts as an SDIO host controller which can communicate over the SDIO bus with a compatible u-blox short range Wi-Fi module acting as SDIO device. The SDIO interface is the only one interface of TOBY-L2 cellular modules available for communication between the u-blox cellular module and the u-blox short range Wi-Fi module. The AT commands interface is not available on the SDIO interface of TOBY-L2 series modules. The SDIO interface supports 50 MHz bus clock frequency, which allows a data throughput of 200 Mb/s. For  more  details  regarding  the  SDIO  interface  usage  and  the  integration  with  a  u-blox  Wi-Fi  module  see  the TOBY-L2  / MPCI-L2  series System  Integration  Manual  [2], the  Wi-Fi  / Cellular  Integration Application  Note [8], and the Wi-Fi AT commands description in the u-blox AT Commands Manual [1].  2.6 Audio  Audio is not supported by “00”, “01” and “50” product versions.  TOBY-L2 series modules include a 4-wire I2S digital audio interface (I2S_TXD, I2S_RXD, I2S_CLK, I2S_WA) that can be configured by AT command to transfer digital audio data with an external device as an audio codec. For more details regarding the I2S digital audio interface usage and the integration with an external digital audio device  as  an  audio  codec  see  the  TOBY-L2  /  MPCI-L2  series  System  Integration  Manual  [2]  and  the  audio  AT commands description in the u-blox AT Commands Manual [1].
