Page 17 of 62 3 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.

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 = 11kΩ ... 16kΩ). EXT-RES# may be left open if not used.

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.

Page 20 of 62 BlueMod+S42 Host UART-RXD UART-TXD UART-CTS# UART-RTS# IUR-IN# IUR-OUT# GND 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 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).

To use this scheme, the user has to implement UICP on host side for the transmitter only to wake up the BlueMod+S42 receiver.

Page 21 of 62 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.

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 pull-down 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 Interface1 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. 1 subject to firmware support, contact Telit for current status

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.

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.

Page 30 of 62 To enter and use BlueMod+S42 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+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.

Page 40 of 62 5.4.3 Analog Digital Converter (ADC) 5.4.3.1 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) 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 ± 1,5% or • External reference pin AREF: min. 0,83V typ. 1,2V max. 1,3V Source Impedance: <5kΩ

Heat above the solder eutectic point while the BlueMod+S42is mounted facing down may damage the module permanently. 6.4 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). Please note that for best possible performance the antenna should be directed away from the application PCB as shown in Figure 19. max.0,5 4,51010max.0,51015no bare copper (exept solder pads for module)no copper and components on any layerno components on any layerprovide solid ground plane(s) as large as possible around17do not place any conductive parts in this area202040areaApplic.

Page 51 of 62 Figure 19 : BlueMod+S42/AI Placement Recommendation 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+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.
