1 Functional description

1.1 Overview

The TOBY-R2 series comprises LTE Cat 1 / 3G / 2G multi-mode modules in the small TOBY LGA form factor (35.6 x 24.8 mm, 152-pin) that are easy to integrate in compact designs.

TOBY-R2 series modules support up to six LTE bands, up to four 3G UMTS/HSPA bands and up to four 2G GSM/(E)GPRS bands for voice and/or data transmission.

TOBY-R2 series modules are form-factor compatible with u-blox SARA, LISA and LARA cellular module families and are pin-to-pin compatible with u-blox TOBY-L cellular module families: this facilitates easy migration from the u-blox GSM/GPRS, CDMA, UMTS/HSPA, and LTE high data rate modules, maximizes the investments of customers, simplifies logistics, and enables very short time-to-market.

The modules are ideal for applications that are transitioning to LTE from 2G and 3G, due to the long term availability and scalability of LTE networks.

With a range of interface options and an integrated IP stack, the modules are designed to support a wide range of data-centric applications. The unique combination of performance and flexibility make these modules ideally suited for medium speed M2M applications, such as smart energy gateways, remote access video cameras, digital signage, telehealth and telematics.

TOBY-R2 series modules include product versions supporting Voice over LTE (VoLTE) and voice over 3G or 2G (CSFB) for applications that requiring voice, such as security and surveillance systems.

TOBY-R2 series - Data sheet

UBX-16005785 - R18 Functional description Page 9 of 46 C1-Public

Feature

Description

GNSS via modem 9

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 Software 9

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

® 9

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 CellLocate® is available via a set of AT commands for CellLocate® service configuration and position

request.

Hybrid Positioning 9

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 modem 10

Full access to 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.

DTMF decoder

During a voice call, the Dual-Tone Multi-Frequency detector analyses the RX speech (coming from remote party). The detected DTMF symbols can be output via the related URC.

The feature can be enabled and configured through the +UDTMFCFG and +UDTMFD AT commands.

Smart Temperature Supervisor

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.

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.

Fast Dormancy

The Fast Dormancy feature, defined in 3GPP Rel.8, allows reduction of current consumption and network utilization during periods of data inactivity. It can be activated and configured by +UFDAC and +UDCONF=61 AT commands.

LTE cDRX

Both the Long DRX Cycle and the Short DRX cycle are supported for LTE Connected Discontinuous Reception, allowing reduction of current consumption and LTE network utilization during periods of data inactivity

Table 3: Some of the main features supported by TOBY-R2 series modules

☞ 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.

UBX-16005785 - R18 Interfaces Page 10 of 46 C1-Public

2 Interfaces

2.1 Power management

2.1.1 Module supply input (VCC)

TOBY-R2 series modules must be supplied through the three VCC pins by a DC power supply. Voltage must be stable, because during operation the current drawn from VCC can vary by some order of magnitude, especially due to the surging consumption profile of the GSM system (described in the TOBY-R2 series system integration manual [2]). It is important that the system power supply circuit is able to support peak power.

TOBY-R200 modules provide separate supply inputs over the three VCC pins:

• VCC pins #71 and #72 represent the supply input for the internal RF power amplifier, demanding

most of the total current drawn by the module when RF transmission is enabled during a voice/data call

• VCC pin #70 represents the supply input for the internal baseband Power Management Unit and

the internal transceiver, demanding minor part of the total current drawn by the module when RF transmission is enabled during a voice/data call

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-R2 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 / 3G Rx diversity configuration.

2.2.2 Antenna detection

The ANT_DET pin is an Analog to Digital Converter (ADC) input with a current source provided by TOBY-R2 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-R2 series system integration manual [2] and the u-blox AT commands manual [1].

2.3 System functions

2.3.1 Module power-on

TOBY-R2 series can be switched on in one of the following ways:

• Rising edge on the VCC pins to a valid voltage for module supply, i.e. applying module supply: the

modules switch on if the VCC supply is applied, starting from a voltage value of less than 2.1 V, with a rise time from 2.3 V to 2.8 V of less than 4 ms, reaching a proper nominal voltage value within VCC operating range.

Alternately, in case for example the fast rise time on VCC rising edge cannot be guaranteed by the application, TOBY-R2 series modules can be switched on from not-powered mode as following:

• RESET_N input pin is held low by the external application during the VCC rising edge, so that the

modules will switch on when the external application releases the RESET_N input pin from the low logic level after the VCC supply voltage stabilizes at its proper nominal value within the operating range

• PWR_ON input pin is held low by the external application during the VCC rising edge, so that the

modules will switch on when the external application releases the PWR_ON input pin from the low logic level after the VCC supply voltage stabilizes at its proper nominal value within the operating range

When the TOBY-R2 series modules are in the power-off mode (i.e. properly switched off as described in section 2.3.2, with valid VCC module supply applied), they can be switched on as follows:

• Low pulse on the PWR_ON pin, which is normally set high by an internal pull-up, for a valid time

period (see section 4.2.8). The PWR_ON line should be driven by open drain, open collector or contact switch.

• Rising edge on the RESET_N pin, i.e. releasing the pin from the low level, normally set high by an

internal pull-up. 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-R2 series can be properly switched off, saving current parameter settings in the module’s nonvolatile memory and performing a proper network detach, by:

• AT+CPWROFF command (see the u-blox AT commands manual [1]).

• Low pulse on the PWR_ON pin, which is normally set high by an internal pull-up, for a valid time

period (see section 4.2.8). The PWR_ON line should be driven by open drain, open collector or contact switch.

An abrupt under-voltage shutdown occurs on TOBY-R2 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 nonvolatile memory and to perform the proper network detach.

An abrupt shutdown occurs on TOBY-R2 series modules when a low level is applied on the RESET_N pin, which is normally set high by an internal pull-up. If this occurs, it is not possible to store the current parameter settings in the module’s non-volatile memory and to perform the proper network detach.

An over-temperature or an under-temperature shutdown occurs on TOBY-R2 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-R2 series system integration manual [2] and the u-blox AT commands manual [1], +USTS AT command.

UBX-16005785 - R18 Interfaces Page 12 of 46 C1-Public

2.3.3 Module reset

TOBY-R2 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 entire module, including the integrated power management

unit, except for the RTC internal block: the V_INT generic digital interfaces supply is switched off and all the digital pins are tri-stated, but the V_BCKP supply and the RTC block are enabled. 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 / host configuration selection

☞ Selection of module / host configuration over HOST_SELECT0 and HOST_SELECT1 pins is not

supported.

TOBY-R2 series modules include two pins (HOST_SELECT0, HOST_SELECT1) for the selection of the module / host application processor configuration.

2.4 SIM

2.4.1 SIM interface

A SIM 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

TOBY-R2 series modules provide the SIM detection function over the GPIO5 pin to sense the SIM card physical presence (as an optional feature) when the pin of the module is properly connected to the mechanical switch of the SIM car holder (for more details, see the TOBY-R2 series system integration manual [2]).

2.5 Serial communication

TOBY-R2 series provides the following serial communication interfaces:

• UART interface: Universal Asynchronous Receiver/Transmitter serial interface available for the

communication with a host processor (AT commands, data communication, FW update by means of FOAT), for FW update by means of the u-blox EasyFlash tool and for diagnostic.

• USB interface: Universal Serial Bus 2.0 compliant interface available for the communication with

a 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

compatible u-blox short range radio communication Wi-Fi modules.

TOBY-R2 series - Data sheet

UBX-16005785 - R18 Interfaces Page 13 of 46 C1-Public

2.5.1 UART interface

TOBY-R2 series modules include a 9-wire unbalanced Universal Asynchronous Receiver/Transmitter serial interface (UART) for communication with an application host 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.

UART features are:

• Complete serial port with RS-232 functionality conforming to the ITU-T V.24

recommendation [14], 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

• 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 DTR input can be enabled via AT+UPSV command

(for more details, see the u-blox AT commands manual [1] and TOBY-R2 series system integration manual [2])

• The following baud rates are supported: 9600, 19200, 38400, 57600, 115200 (default baud rate

when autobauding is disabled), 230400, 460800, 921600, 3000000, 3250000, 6000000 and 6500000 bit/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 following frame format are supported: 8N2, 8N1 (default format when automatic frame

recognition is disabled), 8E1, 8O1, 7E1 and 7O1

• One-shot automatic frame recognition is supported and it is by default enabled in conjunction with

automatic baud rate detection (autobauding): the detection is performed only once, at module start up. After the detection, the module works at the detected frame format and it can only be changed via AT command (see u-blox AT commands manual [1], +ICF).

UART serial interface can be conveniently configured through AT commands: see the u-blox AT commands manual [1] (+IPR, +ICF, +IFC, &K, \Q, +UPSV AT commands) and TOBY-R2 series system integration manual [2].

2.5.1.1 Multiplexer protocol

TOBY-R2 series modules include multiplexer functionality as per 3GPP TS 27.010 [10] 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 available (for details, see mux implementation application note [6]):

• Channel 0: Multiplexer control

• Channel 1 – 5: AT commands / data connection

• Channel 6: GNSS data tunneling

☞ The GNSS data tunneling channel is not supported by the TOBY-R200-02B-00 and the

TOBY-R202-02B-00 type numbers.

2.5.3 DDC (I2C) interface

☞ Communication with u-blox GNSS receivers over DDC (I2C) interface is not supported by the

TOBY-R200-02B-00 and TOBY-R202-02B-00 type numbers.

TOBY-R2 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-R2 module acts as an I2C host which can communicate with I2C local devices in accordance with the I2C bus specifications [16].

For more details regarding the DDC (I2C) interface usage and the integration with a u-blox GNSS receiver, see the TOBY-R2 series system integration manual [2], the GNSS implementation application note [5], 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 "02B", "42B", "82B", and "03B" modules product versions.

TOBY-R2 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 external compatible

u-blox short range radio communication Wi-Fi modules.

2.6 Audio

TOBY-R2 series modules support Voice over LTE (VoLTE) as well as Circuit-Switched Fall-Back (CSFB) from LTE to 3G or 2G radio bearer for providing audio services.

TOBY-R2 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 in PCM mode (short synchronization signal) or in normal I2S mode (long synchronization signal) to transfer digital audio data to/from an external device as an audio codec.

For more details regarding internal audio processing system capabilities, I2S digital audio interface possible configurations, usage and guideline for the integration with an external digital audio device as an audio codec, see the TOBY-R2 series system integration manual [2] and the audio sections in the u-blox AT commands manual [1].

2.7 Clock output

TOBY-R2 series modules provide a digital clock output function on the GPIO6 pin, which can be configured to provide a 13 MHz or 26 MHz square wave. This is mainly designed to feed the clock input of an external audio codec, as the clock output can be configured in “Audio dependent” mode (generating the square wave only when the audio path is active), or in “Continuous” mode.

For more details, see the u-blox AT commands manual [1], +UMCLK AT command.
