3.1
Power Supply
BlueMod+SR require a power supply with the following characteristics:
Typical: 3,3VDC, min.: 2,5VDC, max.: 3.6VDC, low noise (≤ 10mVrms), > 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 types: TOREX: XC6204x332xx or XC6401xx42xx.
If the regulator cannot be placed close to the BlueMod+SR, it is recommended to place an
additional low ESR capacitor with at least 10µF 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.
Note:
EXT-RES# pin can also be output. Use an open drain device or push button to drive it low. EXTRES# must not be connected to VSUP or driven to logic high-level directly. Provide for an 1kΩ
series resistor when driving EXT-RES# from a CMOS output.

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
•
Hardware flow-control with RTS and CTS (active low)
Note: Transmission speed may be limited by firmware. See corresponding command reference
[5] 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 5.6.1) when the UICP
protocol is used (refer to [3] ). This protocol has to be complemented 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 [5] for a functional specification. GPIO[4] can be left unconnected
if this feature is not used.

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 2
3.8
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:

3.10 WLAN Coexistence Interface 3
For implementing WLAN Coexistence with CSR’s Wi-Fi solution the Unity 3e+ solution is
implemented. For non-CSR WiFi solutions only the 3 Signals BT_ACTIVE (BT-ACT), BT_STATUS
(BT-STAT) and WLAN_DENY (WLAN-DNY) are used.

If this interface is not used, these signals may be left unconnected.
If your application needs to use these signals, ask Stollmann for support.
3.11 Slow Clock Interface
Consumption of power during power-down modes can be reduced by feeding the module with a
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,
Stollmann recommends the connection of A-6 to GND (direct connection or pull-down resistor).
Note: 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 at the same time.

3.13 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 Stollmann 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 3.3).
3.14 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.

Notes:
(2)
connection parameters are setup by the central device when connection is established
(3)
no data to be transmitted, central device sends an empty packet (80 bit) then peripheral device answers (empty
packet: 80 bit)
(4)
these are a typical connection parameters used by an iPhone, iPad or iPad mini device in the central device role

Antenna-Gain and Radiation Pattern
If BlueMod+SR/AI is integrated into an end product while the recommendations depicted in 6.4
Placement Recommendation are maintained, the following typical antenna radiation patterns can
be expected.
Radiation Pattern will depend on the end products PCB size, masses in the antenna environment,
housing material and geometrics.

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.

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 is fixed and cannot be removed or replaced by the
end user. The performance of the internal antenna respectively the external antenna has in any

case 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.

7 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.

In this example BlueMod+SR is connected to an MCU supporting RTS/CTS flow control and Hangup.
Firmware update is supported (BOOT0, EXT-RES# connected).
The slow clock oscillator (32,768kHz ) is optional; it helps to save power during power down states.
