BT900-Sx Hardware Integration Guide Intelligent BTv4.0 Dual Mode Module 5 FUNCTIONAL DESCRIPTION The BT900 Dual Mode (BT/BLE) module is a self-contained Bluetooth Low Energy product and requires only power and a user’s smartBASIC application to implement full BLE functionality. The integrated, high performance antenna combined with the RF and Base-band circuitry provides the Bluetooth Low Energy wireless link, and any of the SIO lines provide the OEM’s chosen interface connection to the sensors.
BT900-Sx Hardware Integration Guide Intelligent BTv4.0 Dual Mode Module Refer to the smart BASIC user manual. 5.3 Memory for smartBASIC Application Code User has up to 4Kbytes (TBD) of data memory available for smart BASIC application script. 5.4 RF 2402–2480 MHz Bluetooth4.0 Dual Mode (BT and BLE) (1Mbps to 3Mbps over the air data rate). TX output power of +8 dBm programmable (via smartBASIC command) to -20 dBm in steps of 4 dB.
BT900-Sx Hardware Integration Guide Intelligent BTv4.0 Dual Mode Module Note: The BT900 serial module output is at 3.3V CMOS logic levels (tracks VCC). Level conversion must be added to interface with an RS-232 level compliant interface. Some serial implementations link CTS and RTS to remove the need for handshaking. Laird does not recommend linking CTS and RTS other than for testing and prototyping.
BT900-Sx Hardware Integration Guide Intelligent BTv4.0 Dual Mode Module An I2C interface allows multiple masters and slaves to communicate over a shared wired-OR type bus consisting two lines which normally sit at VCC. The BT900 module can only be configured as an I2C master with additional constraint that it be the only master on the bus. The SCL is the clock line which is always sourced by the master and SDA is a bi-directional data line which can be driven by any device on the bus.

Note, the frequency driving each of the x SIO pins is the same but the duty cycle can be independently set for each pin. FREQ output signal frequency can be set over a range of 0Hz to xMHz (with 50% mark-space ratio). 5.

BT900-Sx Hardware Integration Guide Intelligent BTv4.0 Dual Mode Module 6 HARDWARE INTEGRATION SUGGESTIONS 6.1 Circuit The BT900-series module is easy to integrate requiring no external components on the customer’s board apart from those required by customer for development and in customers end application. Checklist (for Schematic): VCC External power source within the operating range, rise time and noise/ripple specification of BT900.
BT900-Sx Hardware Integration Guide Intelligent BTv4.0 Dual Mode Module nAutoRUN pin and operating mode selection nAutoRUN pin needs to be externally held high or low to select between the two BT900 operating modes at power-up: - Self-contained Run mode (nAutoRUN pin held at 0V). - Interactive / development mode (nAutoRUN pin held at VCC). Make provision to allow operation in the required mode. Add jumper to allow nAutoRUN pin to be held high or low (via 10K resistor) OR driven by host GPIO.
BT900-Sx Hardware Integration Guide Intelligent BTv4.0 Dual Mode Module 6.3 PCB Layout on Host PCB for BT900-SA 6.3.1 Antenna keep-out on host PCB The BT900-SA has an integrated chip antenna and its performance is sensitive to host PCB. It is critical to locate the BT900-SA on the edge of the host PCB (or corner) to allow the antenna to radiate properly. Refer to guidelines in section PCB land pattern and antenna keep-out area for BT900-SA. Some of those guidelines repeated below.

BT900-Sx Hardware Integration Guide Intelligent BTv4.0 Dual Mode Module 7.2 Host PCB Land Pattern and Antenna Keep-out for BT900-SA Dimensions in mm. APPLICATION NOTES 1. Ensure there is no copper in the antenna ‘keep out area’ on any layers of the host PCB. Also keep all mounting hardware or any metal clear (Refer to 6.3.2) on of the area to reduce effects of proximity detuning the antenna and to help antenna radiate properly. 3.
