• We strongly recommend the modules not being soldered more than 1 time after shipping from connectBlue and that the modules are mounted just before the host product is being soldered the last time. Although, connectBlue devices will withstand up to two reflows to an absolute maximum temperature of 250°C.
Page 29: Antenna Issues
Section 5.5 - Mounting Information.Antenna Issues ANTENNA ISSUES The unit cannot be mounted arbitrary, because of the radio communication. The unit with an internal surface mounted antenna (cB-OZS311i) cannot be mounted in a metal enclosure. No metal casing or plastics using metal flakes should be used, avoid also metallic based paint or lacquer.
Page 30: Regulatory Information
Mats Andersson CTO of connectBlue AB If a cB-OZS311 is used within EU a notification must be made to each of the national authorities responsible for radio spectrum management of the intention to place radio equipment that uses frequency bands whose use is not harmonized throughout the EU, on its national market.

Page 36: Appendix A - Application Notes
Section A.1 - Application Notes.Step-by-Step Guide Appendix A - Application Notes Usually only a subset of the available functionality is of interest to the designer. In addition, depending on the host system, the electrical interface can be designed in many ways. The designer can use the step-by-step guide in this chapter as an aid in the design process.
Page 37: Design Examples
Section A.2 - Application Notes.Design Examples A.2 DESIGN EXAMPLES This section contains design examples for all interfaces on J2, J3, and J6. The connector type that suits a specific application depends on the needed signal and the preferred interface type (board-to-board or SMD).
Page 38 Section A.2 - Application Notes.Design Examples A.2.2 Serial Interface The serial interface of the module is Logic Level logic levels and the module can be connected to an external CPU (see section A.2.2.1). An external driver is needed if the module should be on another physical interface like RS232 (see section A.2.2.2 - A.2.2.3).
Page 39 Section A.2 - Application Notes.Design Examples A.2.2.2 External RS232 driver An external RS232 driver is needed if the module should have a RS232 serial interface. See Figure 14 for a complete design example that could be connected to the serial port of standard PC.
Page 40 Section A.2 - Application Notes.Design Examples A.2.2.3 External RS422 driver An external RS422 driver could be used in a point-to-point (full duplex) application (see Figure 15). Figure 15: A complete RS422 interface. Version 1.3 - 2009-12...
Page 41 Section A.2 - Application Notes.Design Examples A.2.2.4 External RS422/RS485 transceiver Note: This function is currently not supported A complete RS422/RS485 transceiver design connected to a bus system need to control the en- able signals of the transceiver. The SerialSelect signals are used for this purpose (see Table 12). The module need to be software configured to the corrected interface, see the Serial Port Adap- ter AT Commands document how to configure the module to the correct serial interface.
Page 42 Section A.2 - Application Notes.Design Examples A.2.3 LED and Switch Design A.2.3.1 BLUE Signal The BLUE logic LED signal is not multiplexed with any other functionality, which makes the design more straightforward (for more information see Figure 17). There are two important notes: A blue LED requires about 3.5V forward voltage drop (cannot be used in a 3.3V system).
Page 43 The RED signal pin is also used to select Logic Level mode (instead of RS232) for connectBlue product with internal RS232 driver e.g. cB-OEMSPA312. The mode functionality is not applicable on cB-OZS311 because there is no internal RS232 driver available. To be compatible with these products check this signal in their Electrical and Mechanical datasheet.
Page 44 Note! The internal 20kΩ Ω Ω Ω pull-up is smaller than on previous product generations from connectBlue. This requires a smaller pull-down resistor (4.7kΩ Ω Ω Ω ) for a low state. If a LED is used and a switch is required to be able to restore the settings, a high impendence buffer need to prevent the signal from being pulled-up via the LED.
Page 45 Section A.2 - Application Notes.Design Examples Figure 23: No restore switch used but a green Figure 24: No restore switch used but a green LED in a 3.3V host system. The status of the LED in a 5V host system. The status of the signal can also be used as input to a host signal can also be used as input to a host controller.
Page 46 Section A.2 - Application Notes.Design Examples Figure 27: A low resistance function switch Figure 28: If the resistance in the switch is not used. guaranteed to be low enough, a safer design can be used. A.2.4 Reset RESET pin can be connected to an external reset source, see Figure 29 for a switch example.
Page 47 Section A.2 - Application Notes.Design Examples A.2.5 A Complete 5V Host System Interface This is a complete 5V host system interface example with an RGB LED and two switches (except the serial interface, see section A.2.2 for information). The design is based on the LM339 Quad OP-amp instead of logic gates.
