3 Application Interface
3.1 Power Supply
BlueMod+S require a power supply with the following characteristics:
Typical: 3,0VDC, min.: 1,8VDC, max.: 3,6VDC, thereby delivering > 25 mA peak
BlueMod+S is designed to be powered from 3V coin cell batteries e.g. CR2032 directly, or any
other power source complying with the given requirements. For optimal performance a stable
supply is recommended. Furthermore it is recommended to place a capacitor in parallel to the
CR2032 3V coin cell battery in order to prolong battery lifetime, by compensating the effects of the
rising source resistance of the battery to pulsed loads. Since the isolation resistance of this
capacitor will discharge the battery in a not insignificant scale, the capacitor should be chosen
under consideration of the following rules:
- capacitance as small as necessary
- nominal voltage as high as possible
- case size as large as possible
- use X7R instead of X5R

3.3 Reset
BlueMod+S are equipped with circuitry for generating power-up reset from the supply voltage
VSUP, as well as brownout detection.
During power-up, reset is kept active until the supply voltage VSUP has reached the minimal
operating voltage. VSUP rise time has to comply with Table 1 for power-up reset to function
properly. A reset is also generated when VSUP falls below the threshold of the brownout detector
(1,6V .. 1,7V with a hysteresis of about 30mV), and is released when VSUP rises above that
threshold.
By holding pin B-1 (EXT-RES#) at ≤ VSUP*0,3V for tHOLDRESETNORMAL ≥ 0,2µs, an external reset (pin
reset) is generated. This pin has a fixed internal pull-up resistor (RPU = 11kΩ ... 16kΩ). EXT-RES#
may be left open if not used.
Note:
The reset-functionality associated with pin EXT-RES# is shared with the serial wire debug
feature (refer to 3.12). Inside the BlueMod+S module, EXT-RES# is connected to SWDIO via a
150R resistor. During a debug session the external reset function is not available; asserting of
EXT-RES# to any level should be avoided.

3.4 Serial Interface
The serial interface of BlueMod+S 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; see chapter 5.4.1).
Transmission speeds are 9600 – 921600 bps and 1Mbps (asynchronous)
Character representation: 8 Bit, no parity, 1 stop bit (8N1)
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#) and GND. 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 5.5.1) 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 (see Figure 4: Serial Interface
Signals) and may be mapped to DSR and DTR, if an RS232-style (DTE-type) interface is used
(see Figure 6).

Figure 5: Five Wire Interface supporting UICP (Minimum Signals needed)
Figure 5 shows the minimal configuration to use UICP for both directions RxD and TxD. To use this
scheme, the user has to implement UICP on host side for the transmitter only to wake up the
BlueMod+S receiver.
When using the TIO 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.
3.4.1 4-Wire Serial Interface
If the host in question is sufficiently fast, a four-wire scheme may be successful. Connect the serial
lines UART-RXD, UART-TXD as well as UART-RTS# and GND; leave UART-CTS# open. The
host is required to stop sending data within a short time after de-assertion of UART-RTS# (there is
room for up to 4 more characters at the time RTS# drops).
Attention: UICP has to be deactivated permanently in this configuration, because signal UART-
CTS# and IUR-IN# become inputs with no PU or PD if UICP is active. This would cause floating
CMOS inputs.
Note: It is strongly recommended to use hardware flow control in both directions. Not using flow
control can cause a loss of data.

3.4.4 Dynamic I/O Signal Type Changes depending on the UICP status
In order to allow customers to use the serial interface with the minimal signal count on the one side
and to reduce current consumption when using UICP on the other side, the BlueMod+S FW
supports the following dynamic I/O signal type changes depending on the UICP activated resp.
deactivated status.
Signal
UICP deactivated
UICP activated
UART-CTS#
I-PD
I-FLOAT
IUR-IN#
I-DIS
I-FLOAT
IUR-OUT#
I-DIS
O-PP
Legend: I-PD = Input with pull-down resistor, I-DIS = Input disconnected,
I-FLOAT = input floating, O-PP = Output push-pull
Signal types I-PD, I-DIS and O-PP may be left open. I-FLOAT has to be driven to GND or VCC to
avoid open CMOS input oscillation.
If UICP is deactivated the pull-down resistor on UART-CTS# helps to keep the serial interface
active if UART-CTS# is open.
If UICP is active and the serial interface is down, UART-CTS# has to be held at VCC and the pull-
down would cause an unwanted constant current drain. Therefore it is switched off in this mode.

3.5 GPIO Interface
It is possible to use the programmable digital I/Os GPIO[0:14] on the BlueMod+S. Their behavior
has to be defined project specific in the firmware.
Unused GPIO pins shall be left unconnected to stay compatible. There may be functions assigned
to some in future versions of the firmware.
3.6 I2C Interface
1
The I2C bus interface serves as an interface between the internal microcontroller and the serial I2C
bus. BlueMod+S is the master and controls all I2C bus specific sequencing, protocol and timing. It
supports standard (100kHz) and fast (400kHz) speed modes. The BlueMod+S as an I2C master
must be the only master of the I2C bus (no multimaster capability). Clock stretching is supported.
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.

The serial peripheral interface (SPI) allows for full-duplex, synchronous, serial communication with
external devices. The interface can be configured as the master and then provides the
communication clock (SCK) to the external slave device(s), or as the slave. The SPI Interface
supports SPI-modes 0 through 3. Module pins are used as follows:
GPIO[2]: SPI-MOSI
GPIO[5]: SPI-MISO
GPIO[8]: SPI-SCK
GPIO[8]/SPI-SCK

3.9 Slow Clock Interface
Even though an external slow clock is not required for BLE operation, consumption of power during
power-down modes can be reduced by feeding the module with an optional 32,768 kHz slow clock
at pin XL-IN/SLCK, or connecting an XTAL (32,768kHz) and two capacitors C1, C2 at pins XL-IN
and XL-OUT.
3.9.1 SLCK Specification (External Supplied Signal)
32,768 kHz +/-250ppm; duty cycle 30...70%.
Signal may be a sine wave, a clipped sine wave, a square wave or a rail-to-rail digital
signal. The amplitude must be at least 200mVpp. DC offset is not an issue as long as the
input voltage is between VSS and VSUP at all times.
connect signal SLCK to XL-IN/SLCK (A6) and leave XL-OUT (A5) open

3.9.3 Connection of an External 32,768 kHz Crystal
Connect the 32,768 kHz crystal and two capacitors C1, C2 at pins A-6 (XL-IN/SLCK) and A-5 (XL-
OUT). The crystal has to comply with specifications given in Table 1. The exact value of C1 and C2
depends on the crystal and the stray capacitance of the layout. Select C1, C2 such that the slow
clock oscillator operates at the exact frequency at room temperature (25°C). C1 and C2 shall be of
equal capacity. The crystal and the capacitors shall be located close to pins A-5, A-6. Avoid long
signal traces.
CL = (C1+Cpin+Cs) * (C2+Cpin+Cs) / (C1+C2+2*Cpin+2*Cs), or
C1, C2 = (2*CL - Cpin - Cs)
Cpin: see Table 4
Cs: stray capacitance, depends on layout

3.10 Test Mode
For homologation purposes the ability of test mode operation like "BlueMod+S_Testmode" or
"Direct two wire UART Testmode" (DTM) is mandatory. The Direct Test Mode (as defined by the
Bluetooth SIG) and BlueMod+S_Testmode are part of the BlueMod+S TIO-Firmware. Please refer
to [6] and [7].
For enabling the different test modes the BlueMod+S provides two IO pins.
The pin Testmode is low active. Active in the following table means connect to GND.
The pin Boot0 is high active. Active in the following table means connect to VDD.
The other two combinations start the bootloader for firmware update of the programmed
firmware. These two modes are not scope of this document.

To enter and use BlueMod+S Testmode or DTM, access to the following signals is required:
BOOT0
TESTMODE#
UART-RXD
UART-TXD
UART-RTS#
UART-CTS#
GND
These pins shall be routed to some test pads on an outer layer, but can be left open during normal
operation when not used.
Please note the UART is required for operation of test modes. During the homologation process,
UART-RXD, UART-TXD, UART-RTS# and UART-CTS# must be freely accessible.
3.11 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 9, the voltage on any I/O pin must not exceed VSUP by more than 0,3V at any
time. Otherwise some current IINJ flows through the internal protection diodes. This may damage
the module (please refer to chapter 5.1 for limits).
There is no problem if the application circuit design and programming can assure that all signals
directed towards BlueMod+S 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 each 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 appli-
cations, that gate off these signals while VSUP is not present.

3.12 Serial Wire Debug Interface
The Serial Wire Debug (SWD) interface (signals 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 them for debugging purposes,
make them available. Please be aware of the nRF51822 pin sharing SWDIO/nRESET (refer to [1]).
On the BlueMod+S module, pin EXT-RES# is decoupled from SWDIO by a 150 Ω resistor; SWDIO
is connected directly to pin SWDIO/nRESET of the nRF51822 chip. Nevertheless, avoid driving
EXT-RES# to any logic level while in debug mode, since EXT-RES# will also be driven by the
BlueMod+S or the debugger, when SWDIO is driven by either of these.
During any debugging session the external pushbutton reset functionality is not available. Please
use the correct reset options of your serial wire debugger. Alternatively, power-off the system,
remove the debugger and power-up again (refer to [1], Chapter 10 Debugger Interface (DIF)).

3.13 DC/DC Converter
The product variant BlueMod+S/DC-DC with FW > V2.003 supports a buck DC/DC converter for
supplying the radio circuit. Used with a 3V coin-cell battery, the peak current drawn from the
battery is reduced by approximately 25%.
The DC/DC converter only works in the supply voltage range 2,1VDC to 3,6VDC, whereas the
BlueMod+S/DC-DC is specified to operate in the supply voltage range of 1,8VDC to 3,6VDC. In order
to fulfill this requirement the DC/DC converter is switched off automatically by FW if the supply
voltage drops below 2,3VDC with 5% tolerance. In this situation a LDO regulator will supply the
radio circuit. The DC/DC converter is switched on again after a RESET sequence if the supply
voltage is > 2,3DC.±5%.
In chapter 5.5 Power Consumption and Power-Down Modes the parameters will be given for
operation with and without the DC/DC converter enabled.
Switching off the DC/DC converter, when the supply voltage drops below 2,3VDC, doesn’t reduce
power efficiency significantly, because the DC/DC conversion factor is close to 1 in this supply
voltage region.
Figure 11: DC/DC Conversion Factor FDCDC versus Supply Voltage
The DC/DC conversion factor FDCDC is the ratio between the supply current drawn by the radio
circuit with DC/DC enabled versus LDO(DC/DC disabled). FDCDC = IRADIO(DCDC)/IRADIO(LDO).
FDCDC = 1 means that the DC/DC converter has no effect, whereas FDCDC = 0,7 means 30% less
current consumption. If FDCDC becomes > 1, the operation of the DC/DC converter causes more
current consumption.

5.4 DC Parameter
All Module I/O pins are connected directly to the Nordic nRF51822 chip without signal conditioning
except for some pull-up/pull-down resistors (as indicated). Therefore the electrical characteristics
are as documented in the Nordic nRF51822 data sheet [2].

The following table is applicable if an external slow clock signal is fed into XL-IN/SLCK. This may
be a square wave, a clipped sine wave, a sine wave or a rail-to-rail digital signal. Frequency must
be 32,768kHz +/-250ppm (refer to 3.9). DC offset is not an issue as long as the input voltage is
between VSS and VSUP at all times. Firmware will detect presence of external slow clock signal at
startup; signal has to stay active as long as the BlueMod+S is powered.

5.4.4 Analog Digital Converter (ADC)
5.4.4.1 Input Voltage Range
It is very important to configure the ADC, so the input voltage range and the ADC voltage range
are matching.
If the input voltage range is lower than the ADC voltage range, the resolution will not be
fully utilized.
If the input voltage range is higher than the ADC voltage range, all values above the
maximum ADC voltage range will be limited to the maximum value, also called the
saturation point.
Input voltage range and saturation point depend on the configured ADC reference voltage (see
5.4.4.2) and the chosen prescaling.
Input Voltage Range = ADC Reference Voltage / Prescaler
Limitation for maximum input voltage is described in 5.4.4.3
5.4.4.2 ADC Reference Voltage
ADC Reference voltage can be obtained from:
Internal band gap reference: 1,2V ± 1,5%
or
External reference pin AREF: min. 0,83V typ. 1,2V max. 1,3V
Source Impedance: <5kΩ
5.4.4.3 Analog ADC Input AIN
When the ADC is not sampling the AIN input pin has very high impedance and can be regarded as
open circuit.
Table 15 shows the internal impedance for AIN during sampling for different prescaler settings.
This impedance has to be taken into account when using additional external voltage dividers.

5.6.3 Antenna-Gain and Radiation Pattern
If BlueMod+S/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. Typical antenna gain is about +2dBi.

5.7 Power-Up Time
The time until the BlueMod+S is able to accept link requests or serial data depends on the
firmware version and on the source for the slow clock. Using TIO firmware version V1.009, the
device is ready (as indicated by GPIO IOA, measured from the release of EXT_RES# or VSUP
rising above 1,8V) as follows:
tDeviceReady 0,7s (typ.) if an external slow clock signal is provided.
tDeviceReady 0,9s (typ.) if an external 32,768kHz crystal is connected.
tDeviceReady 1,7s (typ.) if no external signal is provided so the internal RC is used.

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+S resides
on the PCB side looking up. Heat above the solder eutectic point while the BlueMod+S is mounted
facing down may damage the module permanently.

6.4 Placement Recommendation
To achieve best radio performance for BlueMod+S/AI, it is recommended to use the placement
shown in Figure 19. This is a “corner placement” meaning the BlueMod+S/AI 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 6.5).
Please note that for best possible performance the antenna should be directed away from the
application PCB as shown in Figure 19.

6.5 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
6.6 Antenna Issues
BlueMod+S/AI comprises a ceramic antenna which as a component is soldered to the circuit
board. This solution is functional for a BlueMod+S/AI integrated into a plastic housing.
The performance of the antenna 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.

6.7 Safety Guidelines
According to SAR regulation EN 62479:2010 the BlueMod+S 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+S are to be classified as SELV circuitry. OEM’s implementing the
BlueMod+S 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.
6.8 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.

7 Application Diagram
The following schematic shows a typical application of BlueMod+S. The module is connected to
some MCU running the application layer. MCU and BlueMod+S use the same 3,3V power supply.
The serial interface has RTS/CTS flow control and UICP support in this example. The optional
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.
