BlueMod+S42 Hardware User Guide

1VV0301303 Rev.3 – 2016-08-22

2.3 General Cable Replacement

In case there is no standardized application specific profile available the BlueMod+S42 offers Telit’s Terminal I/O profile, which allows transparent data transfer over UART and supports Secure Simple Pairing, making the pairing process easy and the connection secure. Terminal I/O is available for iOS and Android as well as implemented in Telit’s dual mode module BlueMod+SR.

2.3.1 Industry

BlueMod+S42 can be used to monitor and control motors, actuators, values and entire processes.

2.3.2 POS/Advertising

BlueMod+S42 supports iBeacon or similar applications.

2.3.3 Healthcare and Medical

Usage of Bluetooth is aimed mainly at devices that are used for monitoring vital data. Typical devices are blood glucose meter, blood pressure cuffs and pulse ox meters. Bluetooth BR/EDR and low energy were chosen by the Continua Health Alliance as transports for interoperable end to end communication.

2.3.4 Sports and Fitne ss

In the sports and fitness segment the BlueMod+S42 is used in devices for positioning as well as monitoring vital data. Typical devices in this market are heart rate monitors, body temperature thermometers, pedometers, cadence meters, altimeter, positioning / GPS tracking and watches displaying information from sensors.

Typical: 3,0V

, 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 sca le, th e capaci tor 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.

3.3 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 chapte r 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.
