4. APPLICATION INTERFACE
Power Supply
BlueMod+SR require a power supply with the following characteristics:
Typical: 3,3VDC, min.: 2,5VDC, max.: 3,6VDC, > 80mA peak
For optimal performance a stable supply is recommended. If a regulator is to be used, it
should be a fast linear regulator placed as close as possible to the VSUP pins (E-6, F-6).
Functionality has been verified with the following type: TOREX: XC6204x332xx.
If the regulator cannot be placed close to the BlueMod+SR, it is recommended to place an
additional low ESR capacitor with at least 1µF as close as possible to the VSUP pins (E-6,
F-6 or C-1).

Reset
BlueMod+SR are equipped with circuitry for generating Power ON Reset from the internal
core voltage. A reset is generated when the core voltage falls below typically 1,88V and is
released when it rises above typically 1,92V.
By holding pin B-1 (EXT-RES#) at ≤ 0,5V for ≥ 5ms, an external reset is generated. This
pin has a fixed internal pull-up resistor (RPU = 30kΩ ... 50kΩ) and a capacitor to GND
(100n) which acts as debounce filter. If EXT-RES# is not used, it may be left open.
EXT-RES# pin can also be output. Use an open drain device or push
button to drive it low. EXT-RES# must not be connected to VSUP or
driven to logic high-level directly. Provide for a 1kΩ series resistor
when driving EXT-RES# from a CMOS output.

The pin states as indicated in Table 2 are kept until hardware initialization has started.
Supply Voltage Monitor
Supply-under-voltage detection is implemented using the STM32 embedded supply voltage
monitor PVD. When VSUP falls below a threshold VPVD (programmed to 2,38V ± 0,1V), a
system reset will be asserted.

1VV0301276 Rev. 14 Page 19 of 84 2017-06-07
Serial Interface
The serial interface of BlueMod+SR is a high-speed UART interface supporting RTS/CTS
flow control and interface-up/down mechanism according to the UICP+ protocol (refer to
[3]). Electrical interfacing is at CMOS levels (defined by VSUP).
Transmission speeds are 9600 – 921600 bps (asynchronous)
Character representation: 8 Bit, no parity, 1 stop bit (8N1)
Hardware flow-control with RTS and CTS (active low)
Transmission speed may be limited by firmware. See corresponding
command reference [4] for further information.

Figure 4: Serial interface signals
The basic serial interface (with RTS/CTS flow control) uses only four signal lines (UART-
RXD, UART-TXD, UART-CTS#, UART-RTS#). IUR-IN#, IUR-OUT# and GPIO[4] (see
below) can be left unconnected.
A substantially saving of power during idle phases can be achieved (see 6.6.1) when the
UICP protocol is used (refer to [3] ). This protocol should be implemented on the host side
as well. Signals IUR-IN# and IUR-OUT# should be connected to the host and may be
mapped to DSR and DTR, if an RS232-style (DTE-type) interface is used (see Figure 5).
When using the SPP firmware and applications, call control can be supported by GPIO[4].
Driving GPIO[4] to logic High level during a data transfer phase will “hang up” the connection
and disconnect the Bluetooth link. This signal may be mapped to DSR, if an RS232-style
(DTE-type) interface is used. Please refer to [4] for a functional specification. GPIO[4] can
be left unconnected if this feature is not used.

4.5.1. 3-Wire Serial Interface
When using only GND and UART-RXD, UART-TXD serial lines, leave UART-RTS# and
UART-CTS# open.
It is strongly recommended to use hardware flow control. Not using
flow control can cause a loss of data. When RTS/CTS is not used (3-
wire interface) the DTE may sent a limited number of Bytes (depending
on buffer size) to the UART interface of the BlueMod+SR without losing
data (e.g. 1 kByte by using firmware version 1.310).

4.5.3. Baud Rate Deviation
The information on how to set standard or custom baud rates can be found in [4]
BlueMod+SR AT Command Reference.
Assumed that on both sides the TX and RX baud rates are nominally equal, the total baud
rate deviation is the sum of the host baud rate deviation and the BlueMod+SR baud rate
deviation. The total baud rate deviation shall not exceed 2.5% to prevent loss of data. Some
margin should be considered to cover deviations through the transmission line, e.g. due to
asymmetry in low to high and high to low transitions.
The following table shows the BlueMod+SR baud rate deviation in percent of the standard
baud rates caused by the baud rate generator granularity. Add 50ppm for the tolerance of
the local oscillator over the full temperature range.
Table 3: Standard baud rates and deviations

19200
38400
57600
115200
230400
460800
921600
Custom baud rates (CBR) are generated by a fractional divider according to the formula
Where data types are for MANTISSA unsigned int12 and for FRACTION unsigned int4.
These values will be programmed to the fractional baud rate generator registers.
BR is the resulting baud rate which might not exactly be the targeted CBR due to the
granularity error of the fractional baud rate generator.
BlueMod+SR Hardware User Guide
1VV0301276 Rev. 14 Page 23 of 84 2017-06-07
Therefore the baud rate deviation can be calculated by the following procedure:
If FRACTION > 15
MANTISSA := MANTISSA + 1
FRACTION := 0
Explanation of used functions and expressions:
math.floor(x) returns the largest integer less than or equal to x
math.round(x) returns a number of x rounded to the nearest integer
math.abs(x) returns the absolute value of x

CBR targeted customer baud rate
BR actual resulting baud rate

FRACTION unsigned int4 baud rate register value
GPIO Interface
It is possible to use the programmable digital I/Os GPIO[0:8] on the BlueMod+SR. Their
behavior has to be defined project specific in the firmware.
Unused GPIO pins can be left unconnected.

I2C Interface
1
The I2C bus interface serves as an interface between the internal microcontroller and the
serial I2C bus. It provides multimaster capability, and controls all I2C bus specific
sequencing, protocol, arbitration and timing. It supports standard (100kHz) and fast
(400kHz) speed modes.
GPIO[1]/I2C-SDA and GPIO[0]/I2C-SCL can be used to form an I2C interface. It is required
to connect 4k7 pull-up resistors on I2C-SCL and I2C-SDA when this interface is used.

SPI Serial Peripheral Interface
3
The serial peripheral interface (SPI) allows half/full-duplex, synchronous, serial
communication with external devices. The interface can be configured as the master and in
this case it provides the communication clock (SCK) to the external slave device. The
interface is also capable of operating in multi master configuration. It may be used for a
variety of purposes, including simplex synchronous transfer on two lines with a possible
bidirectional data line or reliable communication using CRC checking.
Module pins are used as follows:
GPIO[2]: SPI-MOSI
GPIO[5]: SPI-MISO
GPIO[8]: SPI-SCK

If this interface is not used, these signals should be left unconnected.
If your application needs to use these signals, ask Telit for support.
Slow Clock Interface
Consumption of power during power-down modes can be reduced by feeding the module
with an optional 32,768 kHz slow clock at pin SLCK.
SLCK specification:
32,768 kHz typ., 30 kHz min., 35 kHz max. Duty cycle 30...70%.
Signal must be square wave, at VSUP-level (see note below) and present as long
as VSUP is powered.
The module’s firmware will detect the presence of a slow clock during the boot process and
switch behavior appropriately. This check does only apply for presence of some clock; it is
not checked if the clock frequency is in the valid range required by CSR8811 (30kHz ...
35kHz).
If this signal is not used, to minimize risk of erroneous pulse detection in noisy environments,
Telit recommends the connection of A-6 to GND (direct connection or pull-down resistor).
Since SLCK is fed to both the STM32 and the CSR8811, the electrical
characteristics as described in Table 11 (VLSEH) and Table 12 (VIH)
apply both at the same time.

Test Mode
This functionality is reserved. Leave pin TESTMODE# open.
Pin Strapped System Memory Boot Mode Invocation
Asserting BOOT0 “high” will invoke the system memory bootloader at start-up. This is
required for firmware update. Thus, access to this signal and a means to drive it at high
level should be foreseen by the customer’s hardware. While not in use, this signal can be
left open or driven to logic low level.
To connect to the module during system memory boot mode, an RS232 serial interface has
to be directly linked to the UART-TXD (F-4) and UART_RXD (D-2) pins.
The bootloader is stored in the internal boot ROM memory (system memory) of MCU. It is
programmed during production. Its main task is to upgrade the firmware to the internal Flash
memory. A communication protocol is defined with a specific command set and sequences.
The firmware upgrade will be done by either
a Telit provided firmware update tool. This is a Windows™ program that contains
the firmware and uses a PC with a serial port for the update
implementing the system memory boot mode protocol on the host system.
If firmware update shall be performed from a host MCU, signals BOOT0 and EXT-RES#
both must be controlled by that host MCU (GPIO ports). Please note that EXT-RES# must
not be driven directly from a push-pull signal (see chapter 4.3).
Operating in a Power Switched Environment
A potential "back feeding" problem may arise, if the module is operated in an environment
where its power supply (VSUP) is switched off by the application. This might be done to
save some power in times Bluetooth is not needed.
As stated in Table 6, the voltage on any I/O pin must not exceed VSUP by more than 0,4V
at any time. Otherwise some current IINJECT flows through the internal protection diodes. This
may damage the module.
There is no problem if the application circuit design and programming can assure that all
signals directed towards BlueMod+SR are set to low (U < 0,3V) before and while VSUP is
turned off. If this is not guaranteed, at least a series resistor (about 1k) must be inserted
into the signal path. This does protect the module but obviously cannot prevent from an
unwanted, additional current flow in case of such signal being at high-level. It may be
necessary to use driver chips in such applications, that gate off these signals while VSUP
is not present.

Serial Wire Debug Interface
The Serial Wire interface SWDIO, SWCLK is normally not used in a customer’s product. It
is reserved for debugging purposes.
Leave SWDIO, SWCLK unconnected. Only if you intend to use it for debugging purposes,
make it available and connect SWDIO via a pullup resistor 100kΩ to VSUP (refer to [1]).
Trace Interface
5
The Trace UART TXD interface provides firmware internal trace information and is normally
not used in a customer’s product. In cases where customer support by Telit is requested it
may provide useful information about BlueMod+SR internal states and processes while in
operation. We recommend leaving GPIO[6] unconnected but allowing access to the signal
(e.g. by routing it to a via or a header).

Opposite side re-flow is prohibited due to module weight.
Devices will withstand the specified profile and will withstand up to 1 re-flows to a maximum
temperature of 260°C. The reflow soldering profile may only be applied if the BlueMod+SR
resides on the PCB side looking up. Heat above the solder eutectic point while the
BlueMod+SR is mounted facing down may damage the module permanently.

Placement Recommendation
To achieve best radio performance for BlueMod+SR/AI, it is recommended to use the
placement shown in Figure 19. This is a “corner placement” meaning the BlueMod+SR is
placed such that the antenna comes close to the corner of the application PCB (red area).
So, the yellow area is outside the PCB and regards to the housing, too (refer to 7.5).
Please note that for best possible performance the antenna should be directed away from
the application PCB as shown in Figure 19.

Housing Guidelines
The individual case must be checked to decide whether a specific housing is suitable for
the use of the internal antenna. A plastic housing must at least fulfill the following
requirements:
Non-conductive material, non-RF-blocking plastics
No metallic coating
ABS is suggested
BlueMod+SR Hardware User Guide
1VV0301276 Rev. 14 Page 59 of 84 2017-06-07
Antenna Issues
BlueMod+SR is shipped with 2 different antenna designs:
BlueMod+SR/AI comprises a ceramic antenna which as a component is soldered to
the circuit board. This is functional for a BlueMod+SR/AI integrated into a plastic
housing. No additional antenna is required.
For an external antenna to be set in, e.g. because the BlueMod+SR is integrated into a
metal housing, the ceramic antenna is replaced.
BlueMod+SR/AP routes the antenna signal to pin A-8.
The gain of the external antenna shall not exceed +2dBi.
When using an external Antenna the antenna must be fixed and shall not be removable or
replaceable by the end user. In any case, the performance of the antenna (whether it is
internal or external) has to be checked within the final integration environment. Adjacent
PCBs, components, cables, housings etc. could otherwise influence the radiation pattern or
be influenced by the radio wave energy.
It must be ensured that the antenna is not co-located or operating in conjunction with any
other antennas, transmitters, cables or connectors. When the internal ceramic antenna is
used, certain restrictions are to be considered.
Safety Guidelines
According to SAR regulation EN 62479:2010 the BlueMod+SR is not intended to be used
in close proximity to the human body. Please refer to above mentioned regulation for more
specific information.
In respect to the safety regulation EN60950-1: 2006 + A11: 2009 + A1: 2010 + AC:2011 all
conductive parts of the BlueMod+SR are to be classified as SELV circuitry. OEM’s
implementing the BlueMod+SR in their products should follow the isolation rules given in
regulation EN 60950-1: 2006.
The PCB material of the BlueMod+SR is classified UL-94V0.
Cleaning
In general, cleaning the modules mounted on the host board is strongly discouraged.
Residues between module and host board cannot be easily removed with any cleaning
method.
Cleaning with water or any organic solvent can lead to capillary effects where the
cleaning solvent is absorbed into the gap between the module and the host board.
The combination of soldering flux residues and encapsulated solvent could lead to
short circuits between conductive parts. The solvent could also damage any labels.
Ultrasonic cleaning could damage the module permanently. Especially for crystal
oscillators the risk of damaging is very high.

8. APPLICATION DIAGRAM
The following schematic shows a typical application of BlueMod+SR. The module is
connected to some MCU running the application layer. MCU and BlueMod+SR use the
same 3,3V power supply. Provisions are made for upgrading the firmware (BOOT0 and
EXT-RES# are managed by the MCU). The serial interface has RTS/CTS flow control but
no UICP support in this example. The Hangup feature to close down the link is provided.
As an option to save power, there is an external slow clock oscillator. All other module pins
may be left unconnected.
