This Hardware Reference documents how the BlueMod+SR/AI and BlueMod+SR/AP can be integrated into customer systems. It addresses hardware specifications of the BlueMod+SR/AI and /AP and requirements of the hardware environments for the BlueMod+SR/AI and BlueMod+SR/AP. Notation: The term BlueMod+SR refers to both the BlueMod+SR/AI and the BlueMod+SR/AP.
BlueMod+SR/AI BlueMod+SR/AP Hardware Reference 1.2 Applications The BlueMod+SR can be used in different applications. Regardless if the application requires high throughput or low energy consumption, BlueMod+SR offers the best of both worlds. Some typical applications are described in this chapter.
BlueMod+SR/AI BlueMod+SR/AP Hardware Reference 1.2.5 Sports and Fitness In the sports and fitness segment Bluetooth 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.
BlueMod+SR/AI BlueMod+SR/AP Hardware Reference 3 Application Interface 3.1 Power Supply BlueMod+SR require a power supply with the following characteristics: Typical: 3,3V , min.: 2,5V , max.: 3.6V , > 80mA peak For optimal performance a stable supply is recommended. If a regulator is to be used, it should be a fast linear regulator placed as close as possible to the VSUP pins (E-6, F-6).
BlueMod+SR/AI BlueMod+SR/AP Hardware Reference By holding pin B-1 (EXT-RES#) at ≤ 0,5V for ≥ 5ms, an external reset is generated. This pin has a fixed internal pull-up resistor (R = 30kΩ ... 50kΩ) and a capacitor to GND (100n) which acts as debounce filter.
BlueMod+SR/AI BlueMod+SR/AP Hardware Reference The following table shows the pin states of BlueMod+SR during reset active. Pin Name State: BlueMod+SR and 100n to GND – use open drain EXT-RES# I/O with pull-up SLCK Input with weak pull-down UART-TXD Input floating...
BlueMod+SR/AI BlueMod+SR/AP Hardware Reference 3.5 Serial Interface The serial interface of BlueMod+SR 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).
BlueMod+SR/AI BlueMod+SR/AP Hardware Reference 3.5.1 3-Wire Serial Interface When using only GND and UART-RXD, UART-TXD serial lines, leave UART-RTS# and UART- CTS# open. Note: It is strongly recommended to use hardware flow control. Not using flow control can cause a loss of data. When RTS/CTS is not used (3-wire interface) the DTE may sent a limited number of Bytes (depending on buffer size) to the UART interface of the BlueMod+SR without losing data (e.g.
Hardware Reference 3.5.2 Baud Rate Deviation The information on how to set standard or custom baud rates can be found in [5] Stollmann: BlueMod+SR AT Command Reference. Assumed that on both sides the TX and RX baud rates are nominally equal, the total baud rate deviation is the sum of the host baud rate deviation and the BlueMod+SR baud rate deviation.

The BlueMod+SR/AP presents no integrated ceramic antenna whereas provides a 50 RF interface. It is highly recommended that you follow the design rule given in the Stollmann Application Note on Antenna design [4]. 3.11 WLAN Coexistence Interface For implementing WLAN Coexistence with CSR’s Wi-Fi solution the Unity 3e scheme could be implemented on request.
A communication protocol is defined with a specific command set and sequences. The firmware upgrade will be done by either a Stollmann provided firmware update tool. This is a Windows™ program that contains the firmware and uses a PC with a serial port for the update implementing the system memory boot mode protocol on the host system.
The Trace UART TXD interface provides firmware internal trace information and is normally not used in a customer’s product. In cases where customer support by Stollmann is requested it may provide useful information about BlueMod+SR internal states and processes while in operation.
BlueMod+SR/AI BlueMod+SR/AP Hardware Reference Notes: a discrete pull-up resistor is used a discrete pull-down resistor is used function depends on firmware DNU: Do Not Use, Do Not Connect If TRACE feature should be used, this signal has to be made accessible in customer hardware NFC support will be available with SPP FW version V1.500 and higher.

BlueMod+SR/AI BlueMod+SR/AP Hardware Reference 5.7.5 Antenna-Gain and Radiation Pattern If BlueMod+SR/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.
BlueMod+SR/AI BlueMod+SR/AP Hardware Reference 5.8 Power-Up Time The time until the BlueMod+SR is able to accept link requests or serial data depends on the firmware version. In the SPP firmware the module is command ready and Bluetooth links are accepted at least 1,1 s after signal EXT-RES# is de-asserted or VSUPx is in a valid range..
BlueMod+SR/AI BlueMod+SR/AP Hardware Reference 6.3 Re-flow Temperature-Time Profile The data here is given only for guidance on solder and has to be adapted to your process and other re-flow parameters for example the used solder paste. The paste manufacturer provides a re- flow profile recommendation for his product.
BlueMod+SR/AI BlueMod+SR/AP Hardware Reference 6.4 Placement Recommendation To achieve best radio performance for BlueMod+SR/AI, it is recommended to use the placement shown in Figure 19. This is a “corner placement” meaning the BlueMod+SR 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).
BlueMod+SR/AP Hardware Reference BlueMod+SR/AP routes the antenna signal to pin A-8 The gain of the external antenna shall not exceed +2dBi. When using an external Antenna the antenna must be fixed and shall not be removable or replaceable by the end user. In any case, the performance of the antenna (whether it is internal or external) has to be checked within the final integration environment.
BlueMod+SR/AI BlueMod+SR/AP Hardware Reference 7 Application Diagram The following schematic shows a typical application of BlueMod+SR. The module is connected to some MCU running the application layer. MCU and BlueMod+SR use the same 3,3V power supply. Provisions are made for upgrading the firmware (BOOT0 and EXT-RES# are managed by the MCU).
