4: Interfaces Specification 4.1 Overview This section describes the interfaces supported by the AirPrime BX310x embedded module and provides specific voltage, timing, and circuit recommendations for each interface. 4.2 UART The AirPrime BX310x provides one UART interface for asynchronous communication between the AirPrime BX310x module and a host device (e.g.
Hardware Integration Guide · Common baud rates are supported—any baud rate in the supported range can be selected via AT+IPR=<uart_baud_rate> command. The device automatically configures the clock dividers appropriately for the chosen baud rate. · Baud rates are persistent post-reset. ·...
Interfaces Specification 4.4 I C Interface The AirPrime BX310x module provides two I C (Inter-Integrated Circuit) dedicated serial ports (bus interface) based on [2] The I2C Bus Specification, Version 2.1, January 2000 (Phillips Semiconductor document number 9398 393 40011). The interfaces use the pins indicated in Table 4-4.
Hardware Integration Guide 4.5 I2S Interface (Digital Audio) Note: Interface support is forthcoming. The AirPrime BX310x provides a 4-wire I S (digital audio) interface that can be used to transfer serial digital audio to or from an external stereo DAC/ADC, and supports the following features: •...

Hardware Integration Guide SDIO is particularly susceptible to tracking impedance and length variations between the SDIO tracks. Ensure that controlled impedance tracking is used, and minimize tracking length between the module and SD slave device. Add series resistor footprints at the host end to decrease the drive current and reduce potential interference, and match the length of all the SD tracks to within 1 mm.
5: General Layout Recommendations In addition to specific requirements for the antenna implementation and clearance of the BX3105 detailed in this document, good mixed-signal layout practices should be followed: • Avoid tracking of high frequency signals near the RF sections of the module. •...
• Bluetooth SIG Additional certifications and details on specific country approvals may be obtained upon customer request — contact your Sierra Wireless account representative for details. Additional testing and certification may be required for the end product with an embedded BX3100/BX3105 module and are the responsibility of the OEM. Sierra Wireless offers professional services-based assistance to OEMs with the testing and certification process, if required.
