Here's yet another announcement that promises to ease OEM development of Bluetooth-compatible products. Considering the protocol's complexity, that's welcome news.
SMART Modular Technologies, Inc. (Fremont, Calif.) is rolling out a product the company calls a Bluetooth PMG-connectivity module (CM). Designed for OEM applications, the CM is a Class-2 Bluetooth-compliant device that has a footprint of just 0.52 x 0.8 inches, with a Z-height of 120 mils (13-mm x 20-mm x 3-mm).
The CM relies on IXI-Sleek software from California-based software developer IXI Mobile, Inc. IXI Mobile designed this Personal Mobile Gateway (PMG) to let both wide-area cellular networks as well as Bluetooth communicate with thin-client devices in so-called personal area networks (PANs).
Acting as a bridge between mobile and PANs, the SMART rendition of the PMG module combines cellular and short-distance wireless connectivity, with micro-router and micro-server functions. As such, it can work as the point of connection between a wireless network and mobile devices such as "smart" watches, pens, messaging terminals, gaming devices, and cameras.
The PMG-CM Bluetooth product uses one pin of its BGA-packaged (ball grid array) RF chip to feed a small antenna. Receiver sensitivity is claimed to be better than -82 dBm (assuming a raw bit-error-rate of 0.1%). On the transmit side of life, the module delivers an RF output of +3dBm (typical).
On the digital side, the unit's interface connector dishes up PCM (pulse-code modulation) signals, a serial stream from a UART, and power. The digital interface also includes a JTAG (Joint Test Action Group) port. Two general-purpose I/O pins are also available.
"The PMG-CM lets OEMs create communication peripherals without compromising time-to-market or adding overhead for product development," contends Robert Ragusano, VP and general manager of SMART's communication products division.
