Application Interface
3.1
Power Supply
BlueMod+S42 require a power supply with the following characteristics:
Typical: 3,0VDC, min.: 1,7VDC, max.: 3,6VDC, thereby delivering > 25 mA peak
BlueMod+S42 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
In case of using an NFC antenna in conjunction with batteries attend to chapter 3.7.1 Power
Back feeding.

Reset
BlueMod+S42 are equipped with circuitry for generating reset from three sources:
•
A reset is held active, when VSUP falls below the threshold of the brownout detector
(VBOR = 1,2V … 1,7V), and is released when VSUP rises above VBOR + VHYST .
The brownout detector also holds the reset active during power up, until VSUP >
VBOR.
•
A reset is generated, when VSUP is > VBOR and increases 300 mV or more, within
300 ms or less.
•
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 = 11kΊ ... 16kΊ). EXT-RES# may be left open if not used.

Serial Interface
The serial interface of BlueMod+S42 is a high-speed UART interface supporting RTS/CTS
flow control and interface-up/down mechanism according to the UICP+ protocol (refer to
UICP_UART_Interface_Control_Protocol, 30507ST10756A). 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
BlueMod+S42\Central AT Command Reference for further information.

The basic serial interface (with RTS/CTS flow control) uses only four signal lines (UARTRXD, 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 UICP_UART_Interface_Control_Protocol, 30507ST10756A). 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).

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 BlueMod+S42\Central AT
Command Reference for a functional specification. GPIO[4] can be left unconnected if this
feature is not used.
3.3.1
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.

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+S42 FW supports the following dynamic I/O signal type changes depending on the
UICP activated resp. deactivated status.

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
thus the pull-down would cause an unwanted permanent current drain. Therefore the pulldown is switched off in this mode.
3.4
GPIO Interface
It is possible to use the programmable digital I/Os GPIO[0:14] on the BlueMod+S42. 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.
3.5
I2C Interface 1
The I2C bus interface serves as an interface between the internal microcontroller and the serial
I2C bus. BlueMod+S42 is the master and controls all I2C bus specific sequencing, protocol
and timing. It supports standard (100kHz) and fast (400kHz) speed modes. The
BlueMod+S42 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.

Power Back feeding
𝐶𝑖𝑖𝑖 = 𝐶𝑖𝑖𝑖1 = 𝐶𝑖𝑖𝑖2 = 4𝑝𝑝
If the NFC antenna is exposed to a strong NFC field, power back feeding may occur. That
means, current may flow in the opposite direction on the supply due to parasitic diodes and
ESD structures.
If a battery is used that does not tolerate return current, a series diode must be placed between
the battery and the BlueMod+S42 in order to protect the battery. An ultra-low forward voltage
schottky diode should be chosen to keep the battery life reduction as small as possible.

Test Mode
For homologation purposes the ability of test mode operation like “BlueMod+S42_Testmode”
or “Direct two wire UART Testmode” (DTM) is mandatory. The Direct Test Mode (as
defined by the Bluetooth SIG) and BlueMod+S42_Testmode are part of the BlueMod+S42
TIO-Firmware. Please refer to tbd.
For enabling the different test modes the BlueMod+S42 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.

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+S42are 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 applications, 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.

DC/DC Converter
The BlueMod+S42 contains a buck DC/DC converter and an LDO for supplying the radio
circuit.
Switching between DC/DC converter and LDO is done automatically based on load to
maximize efficiency.
Used with a 3V coin-cell battery, the peak current drawn from the battery is reduced by at
least 25% by use of the DC/DC converter.

Leave open (1)(2)
If neither flow control nor UICP is used:
•
IUR-OUT#, IUR-IN#
If UICP is not used: leave open
•

purposes.
Leave open. Only needed for debug
Please note, to keep compatibility with future feature enhancements, unused signals shall not
be connected directly to VSUP or GND. Leave open.
Notes:
(1)
Signals must be accessible during the homologation process, refer to 3.9 Test Mode.
(2)
It is strongly recommended to use hardware flow control in both directions.
Not using flow control can cause a loss of data.

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) and the chosen prescaling.
Input Voltage Range = ADC Reference Voltage / Prescaler
Limitation for maximum input voltage is described in 5.4.5
5.4.4
ADC Reference Voltage
ADC Reference voltage can be obtained from:
•
Internal band gap reference: 1,2V Âą 1,5%
•
External reference pin AREF: min. 0,83V
or
typ. 1,2V max. 1,3V

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 14 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.

Antenna-Gain and Radiation Pattern
If BlueMod+S42/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.
Antenna patterns will be updated in final document

Power-Up Time
The time until the BlueMod+S42is 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 , the
device is ready (as indicated by GPIO IOA, measured from the release of EXT_RES# or
VSUP rising above 1,7V) as follows:
•
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+S42resides on the PCB side looking up. Heat above the solder eutectic point while
the BlueMod+S42is mounted facing down may damage the module permanently.
Placement Recommendation
To achieve best radio performance for BlueMod+S42/AI, it is recommended to use the
placement shown in
Figure 19. This is a “corner placement”
meaning the BlueMod+S42/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).
20
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
6.6
Antenna Issues
BlueMod+S42/AI comprises a ceramic antenna which as a component is soldered to the
circuit board. This solution is functional for a BlueMod+S42/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+S42is 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+S42are to be classified as SELV circuitry. OEM’s
implementing the BlueMod+S42in their products should follow the isolation rules given in
regulation EN 60950-1: 2006.
The PCB material of the BlueMod+S42 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.

Application Diagram
The following schematic shows a typical application of BlueMod+S42. The module is
connected to some MCU running the application layer. MCU and BlueMod+S42use 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 an external slow clock crystal may be used. The 32,768kHz crystal can be placed on
customers HW or may be optionally on module. Contact Telit sales. All other module pins
may be left unconnected.
